v0.60.0

Import PNG/JPG/BMP/WebP images and trace them to cuttable vector layers. Posterize mode quantises the picture to a handful of colours and turns each colour region into its own coloured layer (holes included), so it fits the per-layer colour workflow. A preview dialog sets the number of colours, drops the background, and tunes detail and speckle removal before adding. Share a photo to Knutcut or pick one via 'Import image'. High-contrast art (logos, clipart) traces best; photos come out rough.
