[scribus-dev] lcms 2.8 and transparency flattening

[Leonard Rosenthol]

Lcms cant help with transparency flattening.

There are two ways to approach that operation – the easy way or the hard way

Easy way: rasterize the entire page containing transparency.  For extra credit, find the smallest bounding box for complete objects that are impacted and only rasterize those, leaving everything else intact.

Hard way: find the exact pieces that are impacted and rebuild new objects representing those, hopefully as vectors (but rasterizing as necessary)

The reason is, of course, that InDesign flattens transparencies automatically, whereas Scribus doesn't have a mechanism like this.
