Ahoi,

in my current project I must include a bunch of illustrations in my layout, and the text should flow around their irregular shapes (side placement in single text column only). I got the pictures as TIFFs with alpha channel, but of course I can change that.

I’m quite sure I remember that it was possible to let text flow around shapes somehow, but I can’t find documentation or a sample. I’d be thankful for hints.

The metafun manual should have a few examples.

See https://tex.stackexchange.com/a/32308/323 which is based on an example in the metafun manual.

Thank you all! I guess I can reduce the flow cases to <10 and use \parshape directly; thinking in lines looks a bit easier than the MetaPost way. Calculating the MP path from the TIFF alpha channel would be interesting, but is way above my head. I guess it would work like: * preprocessing: - find the outer contour of the image (after some threshold value of color value or alpha channel) - simplify and vectorize that (I remember there were different OS tools/libraries used with FontForge or Inkscape) - convert this outline (SVG or EPS I guess) into MP * within the ConTeXt run: - place the (scaled) picture - preliminary page/paragraph breaking to find where there might be overlaps - calculate the fitting paragraph shape (rectangle minus overlapping part of the scaled outline) - probably some new line/paragraph breaking?
