Generally the resize step will do something, but will do it in a way you won't like. It would distort any image you apply it to that does not have the same aspect ratio as the image you used when recording the macro. And that probably is not what you want. The usual recommendation for resizing images using macros is to use Filters > Distort > Equations which will not have that problem. You can find more on doing that in the Resources section of the forums: https://forum.affinity.serif.com/index.php?/search/&q=macro resize&type=forums_topic&quick=1&nodes=11&search_and_or=and&sortby=relevancy If your macro is truly doing nothing, I'm not sure what might be going on.

Macros record the final numeric results, and thus actions like that kind of resizing can only be applied to images of the same aspect ratio. You will need to use the Filters > Distort > Equations function to do that kind of resizing. Luckily, other users have already provided macros for that which you could use directly or as a model A search for these (and more): https://forum.affinity.serif.com/index.php?/search/&q=macro resize&quick=1&type=forums_topic&nodes=11

Recording a Resize Document (or Canvas) iin a macro records the absolute value that you used, and that will be applied whenever you run the macro. You need to use Filter > Equations to perform the resize operation, so a calculation is performed when the macro runs. Try one of these: or

You can specify the resampling algorithm using Document > Resize in a macro, but the saved macro always uses the original image propeties when running, not those of the image you apply it to. Using Equations avoids this problem, but you cannot specify the resampling algorthm. John

Resizing canvas is a pita in a macro. Transforms are hopeless, Duplicate and Equations are useful but although equations can increase an object's size it will be clipped by the canvas so that needs to be increased first. You can use John's advice to resize to a large number but here is another way. If you duplicate a pixel layer rotate 90° around its centre unclip canvas you will generate a square canvas Then use a fill layer rasterise rotate 45° unclip canvas you will generate a canvas increased by a bit less than x root2 so it's greater than your 20% (Do that step again and the canvas will be almost double the original etc.) The attached macro does this but I'm a bit foxed. The resized fill layer will have partial transparent pixels at the edges I tried a procedural texture of =ROUND(A/255)*255 for the Alpha but that failed I tried applying a curves layer to boost the alpha and that worked a couple of times but fails in the macro So, you can resize, for example, an 800x600 image to either 958 (x1.1975) or 962 (x1.2025) wide, I can't get it to be exactly x1.2 ResizeCanvas120pc.afmacro

Hi Happen to come across this issue as well. Wanted to create a batch making all documents with same height and maintain proportions in each document with their differences in lenghts. Would require a Macro batch setting only in height value, and let lenght value automatically adjust. So far this has not been working. And from what I read here, a Macro batch with Resize Document can not do this. Looked at similar posts here, as well as this one with Walts suggestion using Distort - Equations. This did unfortunately not make much sense as a replacement for Resize Document. But appreciate if you are able to elaborate on this Walt. Cleay, you mentioned something about a workaround, you able to elaborate? As it's 100s of images, manual workaround is not an option. Affinity, if you read this, please look into this. As I understood from this post, this behaviour is "by design", and if so, Macro with Resize Document batch could be in need of an upgrade. Thank you.

@KFreshDetroit, Sorry for the delay. You can easily amend the first part of the macro to resize to 1500px. However, you will need to set the background colour to black before you run the macro (unless any Affinity guru can tell me otherwise). Here is the resizing macro: Layer > Unlock Layer > Rasterize and TrimFilter > Distort > Equations (Enter the following in the x and y fields, then Apply) (x/1500)*max(h,w) (y/1500)*max(h,w)Document > Clip Canvas Layer > RasterizeSelect > Alpha Range > Select Partially Transparent Edit > Fill> Inpainting Select > Deselect The second part would be: Document > Resize Canvas Unlock the link between width and height, set both to 1500. Click on [Resize]. Layer > New Fill Layer (This creates a Black Fill Layer on top of your image, assuming your background colour is set to black. ) Arrange > Move Back One This moves the layer behind your image Here is the macro: Fit to 1500px square.afmacro John

Quickest way is to open a file, resize the canvas by 2 in both directions, run macro 4CopiesManual, assign your Gradient Maps Another way is to run 4CopiesAuto but note that this uses a canvas of 10000 x 10000px4CopiesManual.afmacro4CopiesManual.afmacro so an image size of 2500x2500 maximum. If you use larger images you can re-record the macro according to the following steps: Open a file Start recording Select top layer <ctrl>J Edit/Fill - any solid colour, this is the resizing layer Resize canvas to handle largest image Filters/Distort/Equations x=x/2, y=y/2 - note that this causes partial transparency on the edges and the width will be slightly larger than 2x Select/Alpha range/Select fully transparent - resizing layer Grow selection by 1px Delete key <ctrl>D Clip canvas Delete resizing layer Press V Add Gradient map <ctrl>J Align right Select/Select all layers <ctrl>J Align bottom End recording Manual won't upload, I'll try later though there should be enough in the text above to reduild it 4CopiesAuto.afmacro

Attached is a resizing macro with a slider that allows you to dynamically resize your image's height from 1000px to 100px in 100px increments The slider values goes from 0 to 1.0 Where... 1.0 = 1000px for the height 0.8 = 800px for the height 0.7 = 700px for the height 0.2 = 200px for the height etc etc You can use the CTRL + Arrow keys in the Slider adjustment box to quickly change increments in 0.1 (100px) values But for those of you that prefer using the slider to change the value, the macro has been written so that any values after the first decimal place are effectively ignored. So you do not have to move the slider to precisely 0.600 to get a 600px high image. Any value from 0.600 to 0.699 will always result in an image size of 600px Likewise moving the slider to any value from 0.300 to 0.399 will always result in an image size of 300px, etc, etc, etc Once you have resized the image you would need to perform a Document > Clip Canvas command to get rid of the transparent pixels now surrounding the image Note: The macro has a clip canvas command at the end of it which I have disabled in this demo so you can see the macro working in "real time" but it can be reenabled by editing then resaving the macro if you prefer the macro to do this step for you automagically The Equations formula used in the macro is x*h/clampmax((rounddown(a*10)*100),h) y*h/clampmax((rounddown(a*10)*100),h) This macro has been tested but not exhaustively, it is here as a demo for others to use or adapt as required. The main purpose in writing it was to find a way for the slider to ignore any decimal points values after the first one, which was (eventually) achieved using the "rounddown" command. Note: There is either a bug or misinformation regarding the use of the "rounddown" command which I will file a separate bug report for and link to from this post at a later time Selectively resize image height from 1000px to 100px.afmacro EDIT: The link to the bug report can now be found here

It's not a bug, as far as I know, just the way that macros work. They record the final dimension, not just the action and the inputs. To resize without this issue you need to use Filters > Distort > Equations. There are several macros that use that approach available in the Resources section of the forums. This search should provide some good hints and the macros themselves: https://forum.affinity.serif.com/index.php?/search/&q=Macro resize equations&search_and_or=and

One way to increase an image by a fixed proportion is to use Equations. Use the following macro steps for a 10% increase (1.1-fold): Document > Resize Canvas Enter 5000 (or some arbitrarily large value) in the width box, Click in the central box in the choice of position. Click on [Resize] Filters > Distort > Equations For x enter x/1.1 For y enter y/1.1 Click on [Apply] Document > Clip Canvas (this removes the added blank area) Note that to enlarge the image 1.1-fold, you need to divide the x (or y) value by 1.1. Adding the 5000 pixel blank canvas is to give the image room to expand. You need it large enough to accomodate an arbitrarily-sized sourced image. You could replace the 1.1 by a parameterised version by replacing it by (1+a), where a is the first parameter. I can provide a (parameterised) macro if you wish. John

Generally, to resize a document in a macro, you need to use Filters > Distort > Equations rather than Document > Resize. There are some macros available in the Resources section of the forums to do that. Or, for another alternative: do the Resizing using File > New Batch Job, and have a macro that does the other operations that you run as part of the Batch Job.

I have modified my macro to perform an initial canvas enlargement to a width of 20000px by 15000px. The central lock must be unlocked and the position set to the centre. Note that whatever dimensions you specify here get baked into the macro. It then applies Equations using polar co-ordinates and r=r/3. This enlarges the image threefold. If one of your images is less than a third of the 3000x2000 frame, then you need to increase the 3 to (say) 4. The next steps simply trim the canvas and rasterise it. Now apply Equations again using the same scaling factor for each axis. This preserves the Aspect Ratio. The next steps are to trim and rasterise the image again. The actions with the alpha are to remove any stray blank areas around the edges. An optional final stage is to resize the canvas to 3000x2000 and add a white fill layer behind it. Here are the macro steps to create an image that will fit within a 3000x2000 frame: Layer > Unlock Layer > Rasterise Document > Resize Canvas Unlock, centre and set dimensions to 20000 x 15000 Filter > Distort > Equations Set Polar Co-ordinates and r=r/3, then Apply Document > Clip Canvas Layer > Rasterise and Trim Filter > Distort > Equations Enter the following in the x and y fields, then Apply x*max(w/3000,h/2000) y*max(w/3000,h/2000) Document > Clip Canvas Layer > Rasterise Select > Alpha Range > Select Partially Transparent Edit > Fill> Inpainting Select > Deselect If you want a white background, add the following steps to the Macro: Document > Resize Canvas Unlock and centre, set dimensions to 3000 and 2000 Layer > New Fill Layer This will be white by default Arrange > Move to Back Document > Flatten (Optional) Here is the macro without adding the final steps: Resize to 3000x2000 frame.afmacro EDIT: I have just tried my original macro above on a wider variety of sizes and shapes (orientation). It seems to work for many but not others. The problem seems to be that the canvas expansion in step 3 was insufficient. I have re-written the macro using a canvas expansion of 20000 x 15000. With this modification it works well. However, if you have original images greater than 20000/3=6666px by 15000/3=5000px, you will need to enlarge the canvas even more! I could make the macro to use an even bigger canvas, but the bigger the canvas, the slower it operates.

You cannot use Document > Resize Document in a Macro (well you can, but it does not behave as expected). You can, however, use batch process to do the resizing, or you can use Filter > Distort > Equations in a macro and it will work as expected. I have created a macro to resize an image to a fixed maximum size, see the thread here. The various maximum sizes included do not include 2048px, so here is the macro listing to perfoem that: Layer > Unlock Layer > Rasterize and Trim Filter > Distort > Equations Enter the following in the x and y fields, then Apply (x/2048)*max(h,w) (y/2048)*max(h,w) Document > Clip Canvas Layer > Rasterize Select > Alpha Range > Select Partially Transparent Edit > Fill> Inpainting Select > Deselect Here is a single macro to resize an image to 2048px maximum size: Resize to 2048 max.afmacro I will incorporate this size into my macro library and repost it. The only problem with resizing using equations is that the algorithm used for resizing is unknown. You might like to apply a little sharpening to the image following the resize. John

Resize operations recorded in a macro remember the final size, not the method used to calculate the size. You can use Filters > Distort > Equations as a workaround for specific sizes, but I'm not sure it will work for percentages. Both @John Rostron and @carl123 have posted macros that will resize to fixed values. Perhaps one of them will have more information about using percentages. You can find their existing macros using this forum search: https://forum.affinity.serif.com/index.php?/search/&q=Macro resize&quick=1&type=forums_topic&nodes=11

This is another example where an operation recorded in a macro remembers/records the result. You can use Filters > Distort > Equations in a macro to perform resizing, instead. There are examples of that in the forums; search for macro resize in the Resources forum and you'll find some, for example: or or

Use the following formulas in the W & H boxes of a New Batch Job (NBJ) to resize your images max (2560, min (w, 2560)) max (2560, min (h, 2560)) Then another NBJ applying a macro which converts to sRGB and sharpens as required. If you apply the sharpening macro in the first NBJ then it will be applied before resizing and that's the wrong way round Or, if you must do it in one pass then use Filter/Distort/Equations with the following x= x*max(w/2560,h/2560) y= y*max(w/2560,h/2560) If you wish you can record the sharpening in the same macro or make a separate one and apply both in the NBJ Trouble with Filter/Distort/Equations is that you cannot select the resampling method but if the results are accepteble then fine The attached macro resizes images to a max long dimension of 2560 EquationsResize2560.afmacro

At the moment it is AFAIK impossible to write image size independent macros if you want to use "resize canvas/document" because these operations work on pixels. Problem: Affinity photo should be 360 aware but it isn't really - local adjustment filters and tonemapping leave visible seams. Workaround: One easy way to get around that is to increase the canvas width by 20% (<- this is the problem), use equations to fill the right and left border, make the adjustment and resize the width of the canvas back to the original size - shrink width by 16.66% (<-again a problem) At them moment this can't really be done independent of the image size because a size increase/decrease will be calculated to pixels - so there will be a fixed pixel number in the macro Solutions: The easiest solution would be if Affinity Photo would support resize by percent properly - by that I mean also in macros support expressions in input fields also in macros -> if you put "*1.2" in an input field this expression will also be used in the macro support variables in macros - reading image size into variables which can be used in later operations To give an example - I have written a macro which increases a 360 panorama by 10% on each side and fills the properly BUT it will only work properly with a 10000 x 5000 px panorama (my main publishing size). Would be really good for Affinity photo if the macro capabilities got better - it can really speed up a workflow and make repetitive tasks a lot easier but for that it needs to be possible to do pretty much everything independent of the image size and in a way - that's where percentages come in really handy. 10kBy5kPlus10%eachSide.afmacro

Some time ago I created a set of macros to resize an image to a fixed maximum size, as described here. Recently @DanThePhotoMan asked about resizing to a fixed minumum size here. I have revisited these macros and created two sets, one resizing to fixed maximum size and the others to a fixed minimum size. They are all based on the following sequence for the maximum set: Layer > Unlock Layer > Rasterize and TrimFilter > Distort > Equations Enter the following in the x and y fields, substituting your own maximum size, then Apply (x/MAXSIZE)*max(h,w) (y/MAXSIZE)*max(h,w)Document > Clip Canvas Layer > RasterizeSelect > Alpha Range > Select Partially Transparent Edit > Fill> Inpainting Select > Deselect Where MAXSIZE is from the following pixel sizes: 640, 800, 1000, 1280, 1600, 2000. The set to resize to minimum is similar except that it uses min(w,h) instead of max(w,h) in step 3 (Equations). There is also a pair of macros to resize to an arbitrary size (up to 4000px). This macro pauses to allow you to enter a parameter a. It is convenient to enter this parameter in the form of MAXSIZE/4000, where MAXSIZE is the maximum (or minimum) required size. For example, if you wanted to resize to 3000px, you would enter 3000/4000, which evaluates to 0.75. (You could enter 0.75 if you wanted.) Note that the resizing algorithm in the Equations process is not defined. Here are the macros as a library (.afmacros) file. Resize.afmacros John @Traveler @Gnobelix @affwin @firstdefence

I can only speak for myself but that's not mathematics, it's merely sums. My mathematics ability expired during my final year at school with grad, div and curl, I still remember the headaches. I am certainly not a graphic artist but have had lots of fun over the years starting with Photoshop 4. Filters/Distort/Equations are not for everyone but a few stunts can be pulled with a bit/lot of effort. Using this approach to resize documents is a bit of a pavlova but it's the only way to do it within a macro owing to the way Photo works. One caveat, the resizing algorithm is unknown; I have compared the macro results with all of the options under document/resize and also resizing with the Transform panel but none match

That is a little disappointing, that there is no possibility to combine two layers with equations in a macro. It this a topic for a feature request. The behavior in macros are in other cases also inflexible, Not the input formular of the user is stored in a macro but the result of an equation. The effect is that in a macro no update of a calculation happens but the result which was calculated during macro recording will be used. Example is the resize function.

That's correct, in Macros certain resizing operations will record the actual (when recorded) size value, rather than the percentage or formula used in the macro If you want to resize by percentage in a macro you should look into the Equations filter (lots of examples in the forum)

You might want to consider File > New Batch Job, which provides the ability to resize multiple files as you'd like, and also provides the facility to let you run macros on the files. Just leave the resizing out of the macro, and let the batch job handle that. But if you want to have a macro that can resize images that have different aspect ratios, your macro will need to use Filters > Distort > Equations to accomplish it. There are examples of that in (I think) the Resources and/or Tutorials forum. However, there are also reports of macros using these functions in 1.6 that don't work in 1.7. So you might not be able to use such a macro directly; only as a model. For example: https://forum.affinity.serif.com/index.php?/topic/55541-macro-to-dynamically-resize-an-images-height-from-1000px-to-100px-in-100px-increments-using-the-equations-filter/&amp;do=findComment&amp;comment=282487 https://forum.affinity.serif.com/index.php?/topic/52019-resize-an-image-to-a-fixed-maximum-size/&amp;tab=comments#comment-262387

More as it happens folks! Thanks again for taking the time to use this beta - we couldn't do it without you :) Affinity Photo Team :ph34r: Here's a recap of the new features in Photo 1.5, along with beta versions of the (excellent, in my opinion) tutorial videos which will accompany the features... Focus Merge Support Focus merging allows you to generate a detailed composite image from a number of images focused at differing lengths. Use File -> New Focus Merge to get started. Video tutorials: Focus Merging Focus Merge Retouching Focus Merging Bracketed Images HDR Merge Support HDR merging lets you create a deep, unbounded 32-bit image from a number of exposure bracketed source images. Use File -> New HDR Merge to get started. Video tutorials: HDR: Merging and Tone Mapping HDR: Tone Map Presets HDR: Panoramas HDR: Preprocessing HDR: Advanced Editing HDR: Ghosts Removal New 32bit RGB Editing Mode Photo now offers a full compositing / editing environment for 32bit unbounded images. Video tutorials: HDR: 32-bit Editing 32bit Develop Photo can now Develop RAW files directly into a 32bit document - so all highlights / shadows are preserved and recoverable at any time. Video tutorials: 32-bit Raw Development OCIO (OpenColorIO) Support Photo now support end-to-end OCIO colour workflows. Video tutorials: OpenColorIO Setup OpenColorIO Adjustment Tone Mapping Persona Full tone mapping Persona for both HDR and LDR images. This is obviously best used with an image merged by HDR merge - although you can use it on any image. Video tutorials: Regular Tone Mapping OpenEXR / HDR (Radiance) / 32bit TIFF Import / Export Photo can now import and export .hdr (Radiance, RGBE) and .exr (OpenEXR) images. It correctly deals with 0-alpha cases (as per the OpenEXR spec) and generally operates in linear space. It support multi-layer EXR files and offers control (through Preferences) over alpha association and premultiplication. Video tutorials: OpenEXR Multichannel Import/Export OpenEXR Import Options Macros Using the View -> Studio -> Macro and View -> Studio -> Library menu items, you can access new panels which will allow you to record actions, save them, then play them back later. You can also store them in a handy gallery. Video tutorials: Macros Macros: Equations Batch Processing Using File -> New Batch job, you can queue up processing on a large number of files. You can resize, convert format and apply any number of macros to each file. The batch processing happens in the background - so you can continue working whilst the jobs are processed. Video tutorials: Batch Processing Live Projections Photo 1.5 contains a new mechanism which allows you to edit an image in different spatial domains - we currently support the “Equirectangular” domain (360 pano - Ricoh Theta, etc.). You can use all tools when editing - and you can convert back once you have edited. This is especially useful for cleaning up stitching artefacts, or artefacts at the zenith / nadir of the image. Use the options in Layer -> Live Projection to get started. Video tutorials: 360 Live Editing 360 Advanced Editing 360 Retouching 360 Multiple Views Live Perspective Projection Improved Pixel Tool The pixel tool is improved in 1.5 - you can hold shift when dragging to constrain the direction of painting (sorry we did not get this working sooner!). You can also select what happens when you hold Alt and drag - erase to transparent, erase to background colour, or erase to whatever the nominated snapshot / history location is (like in the Clone tool). New “Pixel Art” Document Resizing Photo now contains an alternative way to resize a document - using well known pixel-art resampling algorithms. If you work with pixel art and want to use this feature, it’s located under the Document menu. Video tutorials: Pixel Art Resize New “Accumulation” Brush Dynamics Many users have asked for “Opacity Jitter”. For us, opacity is a constant thing and will remain constant. However, we have added a new property to brushes - “Accumulation” - which should allow you to get what you need :) Text Styles Affinity Photo now has the same Text Styles support as Designer - it’s all shared code so it should work right out of the box :) New Marquee Modes (Polygonal, Magnetic) Photo now has 3 modes for the freehand selection tool - Freehand, Polygonal and Magnetic. Even more RAW cameras supported Over 70 new RAW cameras are supported. Improved Metadata Mining Our detection of RAW / JPEG / etc. metadata has been upgraded and some serious bugs have been fixed. Massive Improvements to Export Persona Our Export Persona has seen huge upgrades in this cycle - you now have total control of exactly what resolution sets get exported. You can also use our handy batch export builders to quickly generate content for external consumption - ie. Xcode .assets - even Spline compatible metadata can be generated! Layered TIFF Interop Users have constantly asked us to support “Layered TIFF”. Layered TIFF is not a thing. TIFF with embedded data is a thing - and I’m happy to report that we now import embedded PSD / Affinity data and can write TIFF with embedded Affinity data. Halftone Filter We have a marvellous new halftone pattern filter in 1.5 - it can approximate monochrome, colour, circular and line halftones. Video tutorials: Halftone Scanlines Effect Improved Apply Image Filter Users can how use the current layer as the source for Apply Image - or drag any layer from the layers tab into the dialog to use that as thr source. We also offer handy equations in the filter to control how channels are transferred - in an arbitrary colour source. Video tutorials: Apply Image Apply Image: Equations Improved Select Sampled Colour Filter You can now select by intensity in the select sampled colour tool. Equations Filter A new Equations Distortion filter allows users to create custom spatial filters. Video tutorials: Equations filter Macros: Equations Dust & Scratches Filter Many user have asked us for a “Dust & Scratches” filter - so we have made one. It’s extremely useful for removing sporadic small defects in images. Please let us know if it works for you. Video tutorials: Dust & Scratches Filter “Edit in Affinity Photo” Photos extension This is something which we didn’t think we could do - a Photos extension for Mac OS 10.9 and above which simply allows you to use the full Photo app to edit your images - and stores the changes you have made as a layered document. New Colour Picker Tool After literally thousands of requests, we have implemented a dedicated picker tool for colours. New Clone Sources Panel We now have a new studio panel which allows you to store up an unlimited number of global sources for the Clone / Healing brush - it even works across multiple documents. Video tutorials: Clone Sources Clone Sources: Texture Creation Direct PSD Write-Back One of the most requested features - direct write-back to PSD. A number of 3rd party DAM applications will happily deal in PSD - but until now, Photo required you to File -> Export for PSD. No longer! You can now just hit File -> Save! You will need to turn this on - in File -> Preferences - please read the warning there carefully! No Thumbnails Option This is more a Designer feature, but I promised it some time ago so here it is - you can choose (in Preferences) not to write out a thumbnail with your documents. This has the advantage of making your documents use less space - but obviously you won’t get Finder thumbnails, etc. Improved Vectorscope Our old HSL vectorscope is no more - replaced by a vastly more appropriate Rec.709 YUV scope with an improved graticule :) Improved Photoshop Plugin Support We have found a significant bug with our plugin code - it has been fixed :) We are now finding the majority of plugins work properly. Multi-monitor Colour Profile Support Sorry it took so long to get this fixed - we now can profile different on different monitors. Adjustment Performance Improvements Found and fixed a simple issue which made changing adjustment parameters appear to be slow. Fixed. This update also includes literally hundreds of fixes and small improvements, some of which are listed below: - User control over two pass rendering on Retina devices. - PSD import / export improvements. - PDF import / export improvements. - Snapping improvements - candidate-free snapping, gaps-and-spans (Alt key in Move Tool), so much more! - Performance and stability improvements for macOS Sierra. Download: 1.5 RC2

The final macro works, but slowly. The problem is the enlargement of the canvas followed by the enlargement of the image using equations on this large canvas. If the original image is larger than the target frame (3000 by 2000 in this case), then this prior enlargement is not necessary and could be omitted using my original macro. In that case it would run fairly quickly. I would recommend to @Franzi von Fragenfeld (the OP) that, if possible, you separate the larger images from the smaller images and use the appropriate macro. Alternatively, you could run the smaller images through a simple batch process which enlarges them sufficiently. You could even run a batch process on all your images, large and small, to resize everything to some convenient intermediate size which would guarantee that the aspect ratio is not compromised, perhaps 5000 width. The problem is that the Filter > Distort > Equations operations will only operate on the existing canvas. It cannot write to pixels outside this canvas. Thus the canvas smaller than the target needs to be enlarged prior to applying the filter. John
