  1. Affinity Photo 1.9.1 / macOS Big Sur 11.2.2 Custom input controls in the Procedural Texture panel are not displayed in Japanese environment. The layout of the delete button for custom input is also strange. It is displayed correctly when the application language is set to English.
  2. Hi all, I'm trying to figure out how to add new parameters to the Live Procedural Texture but I can't get my head around it. Basically I would like to use the Smoothed bars preset and add a rotation parameter and a way to control the thickness of the black bars and white bars independently, is this possible? Thanks in advance, Juan

  4. It would improve ease of use if the Procedural Texture Filter panel would resize to display more Custom Inputs (up to a reasonable limit) without requiring scrolling or resizing the panel. I am using a number of Dave’s macros which create Procedural Texture Filters with multiple Custom Inputs (up to 8). This either requires scrolling through the visible list three inputs or resizing the panel to almost screen to height due to the Equations region. The macros add significant attribute based selection capability to Affinity Photo, so hoping the team can make some accommodations for th
  5. Here's a funny thing. Load the attached RGB....jpg file. Procedural Texture. Add variable 0..1 called 'xx'. Put the following code (a snippet from some HSL tinkering) into R, G and B channels. var mx=max(R,G,B);var mn=min(R,G,B);var mr=mx-mn;var ms=mx+mn;var ifmo=roundup(mr-.001);var ll1=ifmo*ms/2;var iflo=roundup(.5-ll1);var ss1=ifmo*(iflo*mr/ms+(1-iflo)*mr/(2-ms+.001));var ifrx=1-roundup(mx-R-.001);var ifgx=1-roundup(mx-G-.001);var ifbx=1-roundup(mx-B-.001);var hr=ifrx*(1-ifgx)*(6*roundup(B-G)+(G-B)/mr);var hg=ifgx*(1-ifbx)*(2+(B-R)/mr);var hb=ifbx*(1-ifrx)*(4+(R-G)/mr);var hh1=i
  6. Hello, I want to get a color value of a pixel at (x, y) coordinates. Is there a color sampler function in Procedural Texture Filter similar to texture2D in GLSL? Thanks!
  7. Ctrl+C cause crash when a group has a procedural texture live filter. It seems that this happens when a group has a vector or an image layer together. Group that has only procedural texture or a pixel layer together is ok.
  8. Hi Everyone, I have been on a mission to fill the void in the Macro environment by the lack of gradient support. To this end I was introduced to Procedural Texture and saw some possibilities and started tinkering. The manifestation of this can be found in several working groupings of R,G,B Vignettes and Linear gradient macros uploaded in the Resource section that I will update as interesting developments occur. In this, I will attempt to break down some of the math and show you how I am attempting to work around my limited knowledge of geometry(has been a while since trig) to make
  9. Hello All, I have been inspired by a thread I started this morning on Basic Procedural Texture Deconstruction to allow beginners to see into the process and the math to be able to create their own Procedural Texture. I thought sharing some of my documentation would be a good place to start and fortunately videos are available at Graphicxtra.com. They are a great resource. Unfortunately, not how I got started, but, I am so happy to have found them that I will start seeing if I can work through an entire video at some point. For now, I am still figuring out that gradient macro
  10. With a little help from my friends, I offer a fresh look at linear gradient procedural texture formula. Yes, it happened in a flash this morning, so, examples will have to follow. This is complete with some exceptions that I was experimenting with a little last night... V1.0 Creates very controllable R,G,B linear gradient with edge hardness, contrast, tint, tone, etc. V1.0 needs wants desires 1) Point of gradient spread. (It should be represented as a fraction from location point rx, ry -/+.) 2) Scale controls.(push left/right/up/down) 3) Skew controls.(angular
  11. Is there a panel to input / edit the equations for the Procedural Texture filter in Affinity Photo on iPad? I can't figure out how to find it. Thanks.
  12. For your pleasure...I have been busy working this vignette thing again, and I think, this is getting somewhere. Completely different approach to achieve a more controllable experience in every way to the gradient macro workaround, and well, much, much, more. First, this macro/procedural texture is set up for a round gradient. Like the original, it applies perfectly to vertical and square images. To center the gradient on a horizontal image(should not be off by much), double click the procedural texture layer and use the crosshair over image to drag and reposition. The controls
  13. I'm working on isolating the maximum value colour in each pixel, so in Apply Image I'm successfully using: DR=SR*rounddown(1-(max(SR,SG,SB)-SR)) DG=SG*rounddown(1-(max(SR,SG,SB)-SG)) DB=SB*rounddown(1-(max(SR,SG,SB)-SB)) rounddown is effectively a boolean operator that reduces this expression to 1 or 0, which happens when the R, G or B value is the same as the maximum value. Implementing this in Procedural Texture I'm getting an illogical and different result. R: R*rounddown(1-(max(R,G,B)-R)) G: G*rounddown(1-(max(R,G,B)-G)) B: B*rounddown(1-(max(R,G,B)-B)) In
  14. Today, I was on a search for Procedural Texture formulas and I found one in the help menu, thanks Affinity! Instead of giving you a macro based on that alone, I added (0,1) controls for red, green, blue. This expands the versatility of the radial vignette to create color toning, blends, etc., as well, all in one. The controls are set up for a black round gradient vignette. When applied, the gradient is sized and centered to the image and will add a non-destructive layer above the layer stack. This can be applied from any selected layer or not. Double click on the Procedural
  15. It would be great if variables/custom inputs in Procedural Texture were selectable in macros, rather than just Opacity. Thanks!
  16. Hi, I start with with the procedural texture ( Filters> Colours> Procedural texture) It 's in Lab mode , ( I wanted see LCH if s the easiest way to " move" w color ), Before, I made an simple test. in 1.8 beta, play with channel save as a preset, close the file An reload with another test file BUT By default we have RVB option, sometimes very difficult to reload it , and impossible with live filter option I can export the preset, but I want re import, photo (beta and release) say me Sometimes I have difficu
  17. In the latest release, when creating a procedural, what you type in the equations field doesn't stay. For example: Open up an image Open up the procedural texture filter You should have no equation lines yet Click on the + to create a new equation line. It will just show a 0 in the field now. Change that 0 to x and hit enter or tab. Notice how the display goes back to 0 but the filter actually took effect? If you click back in the field it will show what the equation actually is (in this case just x). If you create another equation line by clicking the + butto
  18. Hi I just installed the new beta and gave it a bit of a whirl. so far the issues I`m seeing are as follows 1. using the square bracket keys to increase/decrease brush size is not working 2. redraw on blur, smudge etc brushes is very slow and resulted in a lock up 3.procedural texture needs sliders not equations. I can't figure out how to experiment with this at all! I suck at math and even simple algebra is very difficult for me but give sliders to visually experiment and this filter will become useful. as it is i can't use it at all. 4. Filter forge 7 works for me w
  19. Hi, would you be so kind and make Procedural Textures' Presets -> Live?
