Yeah, i've downloaded it. 900 pages... you may have to wait a bit for my review.... (not that i'm going to read it whole, but anyway its a lot of material and i'm *really* busy (don't be surprised if i disappear from the lists for a couple of days) >> Since i suppose that quite a few devs may be in a similar situation, i >> think that adding some comments would be a good idea, >> even if they were completely >> obvious for people knowing PostScript. > > There is a reason this file is commented sparingly: it appears in > every PostScript file produced by LilyPond. Hmm. Does it appear in pdfs too? > PostScript is a rather idiosyncratic language, so one can't really > replace knowing the language with liberal amounts of commenting. Too bad. So, just from the description: i understand that there's some sort of strokeadjusted border drawn around the actual rectangle (i'm referring to the thing you called "clipping path"). This strikes me as suspicious: how are we to fit 3 "layers" (strokes or whatever) into something that renders at about 1 pixel width? I mean, when we have a stem (rounded rectangle), its usually ~1px on screen, and in that 1 pixel we squeze strokeadjusted left edge, the rectangle, and the strokeadjusted right edge? Isn't that too much, and isn't this what's causing this "disappearing lines" effect in poppler? >> By the way: do i understand correctly that a rounded rectangle is >> created as two objects - a "sharp" rectangle and a "rounded" line >> around it? > > There is no such things as a "rounded" line, but the corner join style > might be producing circles. That's what i meant by the "rounded line". Obviously you know the terminology better :) > At any rate, this kind of rendition is only used when all of width, > height, and corner diameter are non-zero. And calling painting > operations "objects" is a somewhat strange view. See the second sentence above. Anyway, thanks for explanation.
