Knife Tool - image disappears


Recommended Posts

I "placed" an image and tried to practice using the knife tool.  I'm new at this. Once I dragged the knife tool across the image, the image disappeared completely.  Does anybody know where the image went, and how I can see it again?  Affinity Designer V2 on Windows 10 PC.

Thanks!

Seems a bug.

works if you convert the image layer into curves.

after cutting, you need to re-adjust the fill, as the fill gets wrong dpi and position.

The knife tool cuts vector objects not raster images. You can duplicate the image and then nest each image into the newly created sections to get a pseudo fragmented image.

a simple solution:

  1. create a rectangular shape in same size as the image
  2. nest the image to the rectangle
  3. use knife tools on rectangle

Then you get a perfect result.

In essence: don't use knife tool on image layer. Use on vector shapes, which have the image nested as child layer.
