raster image conversion.
The changes include:
Reworked raster image processing
functions moved from Trace into Retouch page
image preprocessing visible in the Image preview mode
color reduction algorithms
(improved from the previous version)
tering in RBG and Lab

smoothing based on Bilateral Filtering algorithm alows to smooth the image

This option enables the color reduction algorithm. Reducing the number of colors can improve the
contour detection. Set to 0 to disable the color reduction or specify the desired number of colors
application provides different reducing algorithms:

Each algorithm might give a slightly different selection of colors for every picture.
