Cairo won't be truly suitable for a print workflow until it has proper colourspace support. Squeezing, eg, a cmyk pdf to srgb to print on a colour-managed ps printer is harmful. In addition to minimizing rasterization a la cairo, there are a couple of other tricks which would help. In many cases it would be good enough to approximate transparency by just multiplying the colourants by alpha. That isn't true transparency, of course, but is enough for many files which use argb or acmyk purely for convenience. Longer term, both poppler and cairo could benefit from rasterizing to a shading rather than to a pixmap. OpenGL apps likely have suitable algorithms for rasterizing to triangles which p & c could borrow. Rasterizing to a tensor product shading, though, should be able to replicate anything pdf can do without loss of precision. Ghostscript's ps2writer also has unfortunate limitations. Notably, since it only targets level2 ps, it converts CIDFonts to bitmap type 3 fonts¹. 1] from a comment posted today to gs-devel or to their bugzilla -JimC -- James Cloos <[email protected]> OpenPGP: 1024D/ED7DAEA6 _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler
