NotMyFault

I would like to add 2 comments: If pixel perfect results are intended, please ensure you have snapping enabled when adding the bitmap fill and align the start and end node of the fill to integer pixel positions. Otherwise you will get a visible seam (thin line with lighter or darker colors). If you scale the fill, the alignment must be repeated to the actual target resolution. The shape looks like a part from either a larger circle, or a pyramid with round base, e.g. a projection of a 3D surface to a 2D shape. If this is the case then the pattern needs a perspective correction, probably a different for every tile depending on tile position. There is a special method to apply a fill to multiple layers in one step, so each tile gets the correct portion of the fill layer.

Use ellipse shapes rotated a bit with geometry subtract.

I often use the polygon tool set to 3 edges. As long you are keeping the bounding box at 1:1 aspect ratio it will provide the wanted triangle.

I can’t see anything making that this workaround superior to those given before. Try to sell it or build you own software company to find out.

Threshold works on RGB only, not on alpha. Brushes have one color and model opacity over alpha channel. by using a solid backfill layer, solid color + alpha gets transformed into greyscale color + 100% opacity

Thanks for the video. Really helps to clarify. To achieve the same effect in Photo: create a rectangle in canvas size in black color add the diffuse filter invert the inherent mask of filter paint in white over inherent mask with soft brush You can of course create a brush with has the noise pattern baked-in, but aliasing and semi-transparenzy would spoil the effect. Using view/resample mode neigtest neighbor could compensate to some extend. pure 1 bit pixel layers are unsupported in Affinity and Serif said consistently it has no intention to ever do so. You can achieve the same look with RGB/8 or GREY/8 documents but waist 8 to 24 times storage. Posterize adjustment can help, if you need it on alpha channel use the step function or the quantize function in PT filters.

Could you provide an example document (PNG export) showing the effect? you mention many topics who are probably well known in the Photoshop universe, but I never used Photoshop so unsure if I understand in correct. bitmap capabilities = 1 bit color formats? pure black or white (not greyscale)? a “hard” gradient = no clue I'm positive that the effects can be achieved with Photo, but it probably require a totally different workflow.

I Exported a test file having SRGB linear profile without embedding the profile, using ICC profile from document The export PNG shows a different profile BTU 2100. This seems like a bug.

I would love to see the ability to export PNG above 32767 pixel count in x/y direction. The current limit is very unfortunate. All pNG above 32767 will get silently downscaled.

I quickly broke the new function with heavy mis-usage: create a pixel layer with e.g. checkered box rotate layer by about 45° use selection brush to select area move selection with move tool now cycle through selection box. The selection box is located far away from the actual layer content. I don't know if this intentional or a bug, but the combination of the new selection box with pixel selections, rotation, and moving pixel content can get quite confusing.

Revised list of steps: open RAW file set lens correction / vertical to -100% develop in photo, use crop to increase canvas by factor 2 re-enter develop persona activate crop tool rotate cropped area I'm unable to provide a new video at this time as my mouse movements are not fit for video and would require too much cutting.

Some users request to get the blend mode dissolve. While waiting, you may use a simple procedural texture filter to achieve the same effect with more flexibility. Just add the filter from this document, and adjust the opacity parameter. The filter layer must be nested to masking position of the parent layer. Please note that I might have to delete the video at some time when I exceed my storage quota. You can create the PT filter from scratch: add formula step(noise(rx,ry),a)*A add input variable named a of type 0-1 You may use any of the noise functions, e.g. perlin noise. Bonus: you can adjust the point of origin. While the PT filter UI is open, use the mouse and click at the visible canvas. Then click-drag to move the origin.

Does this apply for pixel layers, too? If yes, can you reset the box again to unrotated to avoid blurriness (imagine You used it only temporary for some alignment with other layers)

In my experiments it does.

He did, but did not apply. it was reset in the second he started to rotate. In my video you see that I had extended the canvas via crop before starting the process.

You can access any channel of an RGBA pixel layer individually and convert it into a color or alpha channel. the channels panels does this „destructively“ by writing the data from a source channel to either spare channel or selected color / alpha channel of another layer. The color mixer channel allows to mix channels freely and non-destructively, i use it a lot for this purpose. there are some principal limitations which cannot be overruled at this time in Affinity apps: When you have layers atop of each other in layer stack, then layer blending will apply, you must choose one of the pre-defined blend modes, no option to define blend modes on your own you can choose blend gamma the equations filter allows to define own blend Formulars, but it is destructive only. The alpha channel is always treated differently in multiple aspects, e.g. Zero values in alpha will zero out RGB channels, too alpha blending cannot be adjusted in any way. Blend modes will modify mixing of RGB values, but except erase blend mode all other will mix upper and lower level based on alpha. Alpha channel does not use gamma correction, whereas RGB/8 and RGB/16 will always use gamma corrected blending. But you can adjust blend gamma from default 2.2 to 1.0 so all channels use same gamma. The blend profiles in blend options are the only exception (this is a bug) and use gamma correction by mistake. when you want to use alpha aware adjustments like channel mixer, levels adjustment, curves adjustment, there are multiple unfixed bugs since years, e.g. currently a nested levels adjustment does not work correctly on alpha channel so it is a game of lots of experimenting what works in Affinity and what does not work. As long as you are able to keep the layer structure very simple, you have a good chance.

great to hear. Can your share the actual solution in your case?

The document units are pt (points) in the video. you need to use px (pixel) to achieve a 100% accurate pixel matching. But it seems ok when i changed this in document setup. Which size of the placed image do you want to achieve? identical physical units (e.g. 10*6 cm): use zoom to 100%, and measure the size of the screenshot. identical pixel size (e.g. 1613*889px with the rectangle used to crop): use zoom to pixel https://affinity.help/publisher2/en-US.lproj/pages/GetStarted/zoom.html Note that some displays and/or screenshot tools do not report the correct DPI. Please use a ruler to measure the results for your test image and compare them to what Affinity apps are reporting. The Publisher document reports 96 DPI, and it is save to assume that you actually use a retina display with much higher DPI. This could explain the difference.

It is possible to achieve the same effect with help of procedural texture filters. Can someone please provide example images generated in PS (layer a, layer b, result of blending with alpha of layer a set to 25/33/50/66/75/90%)?

Pedanterie Mode: Affinity does not use premultiplied alpha, except the file format mandates such a format (I don’t know any). It only erases RGB values to zero whenever alpha gets to 0. And you probably know the workarounds. Instead of PT filter you can use any of channel mixer, levels adjustment, or curves adjustment.

Use rasterize after changing size to ensure the layer gets the document DPI in x/y axis. I think the rectangles intentionally show the aspect ratio of the stretched layer.

This bug is causing the issue. Wrong link removed: It is an unfixed bug in V1 and V2, or related to a fixing attempt creating new issues.

I assume a bug It in Photo V2.3. It only works when the adjustment layer is placed above the bitmap layer. Even using the Swiss knife trick by grouping the pixel layer dit not resolve the issue.
