potential bug layer fx / clip canvas


Recommended Posts

Hi,

when adding 2 outlines

  • first inside,
  • second outside after adding a group,
  • clip canvas overshoots and reveals 4 transparent pixels on every side (alpha = 0 for every pixel)

The document has a snapshot just before hitting clip canvas, so you can try it on your own.

Windows 10,

  • 1.9.2.1035, OpenCL ON and OFF same result
  • 1.9.4.1065 beta, OpenCL ON and OFF same result

Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

Same on Mac, APh beta 1.9.4.243

The bug is already within the simple Outline effect itself:

  • 0 px (!) Outline effect on the inside adds 1 px alpha border on the outside
  • 1 px Outline effect on the inside adds 2 px alpha border on the outside
  • and so on…

I.e. just having the checkbox "Outline" active without doing anything else will add a 1 px alpha border

Another way Affinity helps the creatives. 50% off the price, and get up to 4 transparent pixel for free ;-)
