how to apply water color filter to drawing inkscape

Illustrator uses a different kind of algorithm for tracing which processes the image in smaller bits at a time. I think you are on a right route with this already -the 256 colour limit and the approximate colours etc. The corresponding part in the manual is here. Makes sence if thinking of that covers the full lightness range available in the colour model used.Īs an artifact edges can be bit washed out at otherwise sharp lightness transitions and hue can be visibly off.Īlso the rendering gap issue can be prevalent -seeing through between separate path edges next to eachother.Ī cheap trick to handle that is running two scans.įirst, run one with multiple scans in colour mode at a lower number of scans, then put another scan above it with a higher number. Side effect that there is a 256 scan number limit (as far as I know). Then uses a process to average the colour of the given tone and uses that hue/saturation value on the output paths. Inkscape uses potrace which as far as I know captures the whole image in one, splits up the lightness channel and traces every tone value as a single scan, Multiple scans can give you a half decent result.

Although svg filters are generated only on the rendering level, they are live and theoretically they can be exported in a higher resolution -can generate a closeup blot texture. The other suggested route was to use a filter substitute. Can hardly imagine someone cutting out each layer of the trace with a vinyl cutter. If it doesn't need to be explicitely vector content.

Thus in my humble opinion it's a bit pointless to vectorise a paint blot texture. At some point you'll max out the rendering/processing resources so you'll have to stick with a direct output source.Īdditionally, by vectorising a raster image you won't get any 'unseen' details.Īs a result a vector substitute theoretically can look sharp only in a smaller resolution than the original raster image. That cannot be followed with the infinite details. Inkscape's svg -scalable vector graphics- and any other vector format means a theoretically infinite zoom range. Problem with such textures is the fractal-like nature=the more you zoom in the more details you (are supposed to) get.
