SimSun, a Chinese font bundled to Microsoft Windows, uses the patented hinting instruction very heavily to stretch the glyphic component to form composed glyph shape. # Except of SimSun, there are several fonts # showing similar problems, but SimSun is # the most popular example. To rasterize such fonts to the shape which the font designer expect, the patented hinting technology is essential. To provide the liberated software products, many free softwares use a TrueType rasterizer without patented hinter. Thus, the shape of SimSun is very heavily broken. Fortunately, the known patents of TrueType hinter are expired recently, so the latest FreeType library enables TrueType hinter by default. Therefore, I recommend you to ask the system administrator to update FreeType library to the latest version. Or, you can use older FreeType with non-default configuration to enable TrueType rasterizer. Regards, mpsuzuki P.S. Albert, should I write some document for web page to explain about SimSun issue? I think the number of posts about SimSun issue in poppler list is more than that in FreeType list... _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler
