After some research, I figured out that italic version of a font can be done by matrix if I don't have a italic version of that font on my system. Like the following:
// italic float lean = 0.5f; FT_Matrix matrix; matrix.xx = 0x10000L; matrix.xy = 0x10000L*lean; matrix.yx = 0; matrix.yy = 0x10000L; FT_Set_Transform(face, &matrix, 0); Does gnash need this? Maybe I can create a patch about it. This is the SWF. The text is in Simplified Chinese. 2012/11/18, Sandro Santilli <s...@keybit.net>: > Could it be that Gnash is using device rather than embedded > fonts ?
