Why not any other color? > Because the code is buggy I'd happily try to fix the code, if somebody tells me what the startPage method is supposed to do. >> - Apparently the method is rarely called: The renderToArthur method >> in file poppler-page.cc, for example, does not call it. > Are you sure about that? renderToArthur calls displayPageSlice that calls displaySlice that calls createGfx that calls Gfx constructor with pagenum that calls startPage Well, I said 'rarely', not 'never'. :-) In particular, I had to make the renderToImage method fill the page with the page color, to get a background at all (in 7e844eae94bc4eda1c6dcc3460840b25f4ca7898) The code in startPage didn't seem to have any effect. But I readily admit that I was never quite sure what the proper location is for the code that initializes the page background. Tangentially related: What is the precise meaning of the IgnorePaperColor flag? Does it mean 'make the background transparent'? >> - Most importantly: We want to use ArthurOutputDev to render type3 >> glyphs. But they should have a transparent background, or rather, >> no background at all. > I don't understand this reasoning. The type3 code in the attached patch is partially cargo-culted from the cairo backend. It creates new ArthurOutputDev and Gfx objects for each glyph, and uses them to render a single glyph into a QPicture. The cairo backend calls startPage on the output device, which in the case of the ArthurOutputDev leads to the effect that each glyph has a white rectangular background. You will notice that when rendering type3 text on a non-white background.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
