...because the screen resolution is what counts.
But resampling while you resize sharpens the image, and - correct me if I'm wrong - it never creates artifacts.
An appropriate downsizing algorithm would probably sharpen an image. However, I would be reluctant to claim that it never created artefacts.
If you are upsizing, then it is much more dependant on the kind of image - and on the algorithm. It would also be more likely to cause artefacts because it has to create pixels which were not there before. Having said that, modern specialized upsizing software can do amazing things.

If you are using these images in a website, then the dpi is irrelevant. What counts is the xizein pixels.

Isn’t that what ‘flip horizontally’ plus ‘flip vertically’ does?
Yes, but it also allows all the angles in between.

So what you actually need to do is to rotate the map rather than flip or mirror it.

I have now re-installed Photo 1.6 and recorded my Change DPI macro for 120ppi.
It works OK with Photo 2.4.1
I attach below the macro Change DPI to 1201.6.afmacro
and the updated macro library to include this macro Change DPI 1.6.afmacrosJohn

I have recorded my macro to change dpi to 120ppi. I was just about to upload these when the Affinity site crashed! I will try again when I have had my tea!

I have been recording macros to change the dpi of an image without changing the physical size. These macros will not work in the current versions of Photo, but did work in version 1.6. I originally had a copy of the installation file for v1.6, but this was one of the casualties of me transferring to a new computer. I still have a licence for version 1, but I am told that version 1.6 is no longer available. Would it be possible to obtain a copy of the v1.6 installation files. The macros I originally recorded in v1.6 still work, but some users would like versions that create a different dpi to those I already provide.

If you first create your series of bars using Power Duplicate, you can then use equations on the entire image:
Filter > Distort > Equations
In the Equations box enter
x=x
y=y+150*sin(6*pi*x/w)Then click on Apply
It should give something like this:

Yes, impressive. The depth of field is narrow, but most is in foocus, notably the brakes on the antennae.
What is it? I could probably work out what it is from my key (written by my old boss), but I would guess something like a male common mosquito Culex pipiens.

I recorded those dpi-changing macros in V1.6 (I recall), the version before this error crept in. I have recently installed a new computer, so I currently cannot use this old version. When I do, I will record a 120dpi version.

When you download the installation files, the default is to use the MSIX version. You are given the option of an MSI version, but it offers it (unnhelpfully) as an EXE file - it does have an .exe suffix. Just read down few lines to find it.

I am about to transfer everything to a new computer. I have the information supplied by Affinity: I just re-install on the new computer. However, I seem to have lost my passcode for the V2 apps. (I do have them for V1).
How can I retrieve my passcode?

Hi,
I don't know if there is a more recent topic about this subject.
Is there now (2024) a way to resize an image AND specify the method (bilinear, bicubic, etc ..;) in a macro ?
ThanxYou 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.

Whilst in nitpicking mode, can I point out that scientific names have only the first word (the generic name) capitalised. The remaining words are all lower case. For example Homo erectus pekinensis.
The central skull should be named Homo habilis, not Homo habitus.
A very nice poster!

There are two ways of doing this.
Either: Locate the default plugin folder. You can find this from the Photoshop Plugins box. Copy your plugin to this folder.
Or: In the Photoshop Plugins box, Click on Add, then navigate to the installation folder for your plugin and select the folder where the plugin resides.
Have you done either of these?

I have come to this thread rather late, but would my macro to resize to a fixed maximum size work as part of a batch job?

You need to visit the Topaz forum for gigapixel. Just Google 'Topaz gigapixel forum'.

Hello @siarkie, and welcome to the forums.
When you say "no longer there", do you mean that it is no longer in your macros panel, or that it is no longer where you saved it on disk?

Have a look at this. My post is at the end of the thread.

Prefs → External Viewer → choose APh
Works for me with no problem on Windows. Note that this is from the VueScan menu system, not Photo.

How can I resize in an macro?

Could you clarify how you want your image resized? My macros work on absolute pixel sizes not percents. I could create a modified version if you tell me exactly what you want.
