  1. Also please make the displacement map viewable / editable similar to a mask.
  2. You wanted to say "x_input = 2*x_output" I suppose
  3. He said "For *output* pixel x=25, apply equation x=x*2 to read from *input* pixel 50.." Since 50=25*2, so he meant InputX = OutputX * 2.
  4. Sounds like a re-occurring issue with understanding terminology used by many people. "Non-destructive" is often understood as having the ability to do steps A, B, C, then return to whatever changes/settings were applied at step A and being able to modify them withing having to redo steps B and C, and still get the same image as if you would have re-done steps B and C. You might say that "non-destructive" is not a good name for this ability, but you should understand that it is viewed as a benefit by many. Since Affinity obviously aspires to be non-destructive in this sense with the many live adjustments, so it makes sense to point out that neither of the solutions presented can achieve that. Consider step A to be the creation of the shape, step B being the creation of blur layer, and step C being the copy of the shape to be also a mask of the blur layer. You can not change the parameters or type of shape (step A) and get a consistent result, without also repeating step C and copy the new shape to be mask of the blur. Edit: Note that I am assuming that one would like to reproduce the original Background Blur, not just a blur masked to a shape. In proper background blur you have a shape/image with it's own colors and when that is blended in, the background color used for blending is blurred before blending. See the animation with the watch earlier where the layer with background blur has a darker gray color and text as well.
  5. Since the equations are used to determine what the input x and input y are, the x and y occurring within them will surely refer to output x and output y. I don't think they went and implemented an equation system solver!
  6. Please see screen-recording. This time a mask is applied to a shape, but not much difference.
  7. Results are consistent with the origin being at the top, and y being further and further negative going down.
  8. Using AP on Win10. When a pixel layer is alt-clicked, the layer contents are displayed in isolation. If in this state the pixel layer is deleted by dragging it into the bin in the layers panel, the image shown is refreshed and the deleted layer is no longer shown. However if you alt-click a mask of a layer, show the mask in isolation, and then delete the parent layer of the mask, thereby the mask as well, it still remains to be showed in the image area. It should refresh in the same way instead to not show the no-longer-existing mask.
  9. It is already answered. The feature is there in Affinity Designer. While editing your document in AD, you can create a text on a circle, then return to Affinity Photo to continue other edits in your document. This was obviously a conscious decision on the part of the devs. In order to be able to use the features of both Photo and Designer, you need to buy both Photo and Designer (DUH).
  10. This will again recolor the whole image. Anything not completely white would take on a shade of blue. I think you misunderstand OP. He has an image with many colors, with a black grid on top, all within a single pixel layer. And would like to recolor the pixels of the black grid.
  11. Won't this make any non-white area of the image partially transparent, and this partially effected by the blue coloration?

    LAB macros

    Hi, Here is a library of macros of various LAB operations. It can do - Selective desaturation of LAB channels - Separate LAB channels to greyscale layers without switching to LAB mode - Join back LAB greyscale layers to a composite image without switching to LAB mode - LAB color contrast boost Enjoy! As for the file size being 4MB for a few macros, I have no idea, it is probably a bug. SH LAB tools.afmacros
  13. Hi, After recording a macro you can make blend mode modifications in the macro customizable by clicking the corresponding eye icon. However, unlike the opacity adjustment customization in macros, you can not assign a label to the blend mode dropdown that is displayed when the macro is played back. This is not particularly helpful, the macro dialog may have multiple blend mode drop-downs with no way to communicate their purpose or role. Please add a modifiable text label for blend mode customization in macros the same way as for opacity.
  14. Steps to reproduce: 1) Load some raster photo 2) Record a macro which duplicates current layer, and modifies the opacity and blend mode of the copy 3) Make both opacity and blend mode adjustable in the macro by clicking the two corresponding eye icons 4) Remove the duplicate layer 5) Replay the macro 6) While the macro options dialog open try modifying the opacity and blend mode in it. The preview only refreshes when the opacity is changed, but not when the blend mode is changed.
  15. Serif says its ok to create threads for requests which were already mentioned before sometime (second paragraph)
  16. I would actually like to record making a pixel layer or even a layer group into a mask, not by Rasterize to Mask, but in the same way as dragging it into the mask position. Assistant doesn't help with this. All that would be needed is a menu item in Arrange menu, same as Mask to Below. Pretty minor request in my opinion.
  17. Hi MEB, This creates what looks like an Orton effect by varying the opacity of the blur. The middle portion is a blur with the contrasty image overlaid. If the radius of the blur would be varied that would make it possible to create a gradually out-of-focus effect. Maybe Field Blur better fits OP needs? (A further improvement of that filter would be support for blur radius driven by a pixel mask)
  18. @MEB , are monitor color profiles ignored for the Navigator panel? Because that doesn't have the yellow cast in the screenshot.
  19. Hi, When using Curves Adjustment layer and selecting LAB color space for the curves adjustment for an image in RGB space, the histogram shown behind the curve is incorrect. It still shows the RGB channel histograms behind, such that Lightness curve has the Red channel histogram, AOpponent has the Green channel histogram, and BOpponent has the Blue channel histogram. This is very misleading and even worse than not having a histogram. The same happens for CMYK curves.
  20. Besides "why you need this?", I wanted to point out the answer to the OP: Affinity does not provide the feature to turn any pixel image into curves or vectors. It can only go the other way. If one has a distressed mask in curves to start with, one can do the cutting out you are looking for.
  21. Both single-image defocus estimation and neural networks are possible solutions for this. I am just saying that Affinity doesn't provide the tools for us to do either, and I think also doesn't implement either of them itself. Remove Haze filter probably uses some simple heuristic of detecting grayish gradients and make them contrasty.
