Making some tests I found out that when not calling the generate_font_bitmap(), display_glyph_records() (in text.cpp) receive texture_glyphs for which is_renderable() returns false.
texture_glyph::is_renderable() is implemented as m_bitmap_info!=NULL. and the texture_glyph class exposes a set_bitmap_info() function. This seems intentionally like the solution I would have used for the bitmap_character_def, the only difference is that in current code the set_bitmap_info() functionis NOT called from within display, but only from fontlib::generate_font_bitmaps() or some other descendent function. So, if I understand your plan correctly, in order to fix this I should, whenever texture_glyph::m_bitmap_info is NULL, call the renderer to create it and cache it back to textur_glyph, correct ? --strk; On Mon, Oct 02, 2006 at 01:32:39PM +0200, Udo Giacomozzi wrote: > Hello strk, > > Monday, October 2, 2006, 12:34:55 PM, you wrote: > s> See bug https://savannah.gnu.org/bugs/?func=detailitem&item_id=17385. > s> I'm looking at it and I think this is related to what you're talking about. > > It seems that fontlib.cpp generates bitmaps for each glyph in the > movie.
