I'd like to place some plain photos rotated (say 12°) and with a blurred shadow above some colored elements, i.e. the shadow must use transparency. I guess I could get such using ImageMagick, but is there a possibility using ConTeXt or one of its favourite friends? I'd prefer a solution that works with CMYK data.
Creating a semi-transparent backdrop with metapost is quite simple, but I am not sure whether that works with cmyk, you'll have to try yourself. Code goes something like this: \startuniqueMPgraphic{texthole} for dx = 0 upto 40: dy := dx; wa := 10 + dx; wb := \overlaywidth - dx - 10; ha := dy + 10; hb := \overlayheight - dy - 10; fill (wa,ha)--(wb,ha)--(wb,hb)--(wa,hb)--cycle withcolor transparent("normal", .04,white); endfor; \stopuniqueMPgraphic
If there isn't - is the transparency of PNG usable?
Sure, and may use less resources than mp drawings, but that is definitely RGB Best wishes, Taco
