More … This also seems to depend on the font file. If I load Calibri (num_fixed_sizes == 6) then I get back a bitmap with certain sizes, but if I use SansSerif (num_fixed_sizes == 0), I always get back a FT_PIXEL_MODE_GRAY.
Also, if I set num_fixed_sizes in Calibri to 0, then it also always returns a FT_PIXEL_MODE_GRAY, so for the moment, I am good JLM When I set the char size to certain values, I get back a bitmap instead of a grayscale image and many of the values in the slot struct make no sense.
How can I force the system to always return a bitmap with the pixel_mode of FT_PIXEL_MODE_GRAY ? for ( n = 0; n < text.length(); n++ ) { char c = text.at(n); FT_Set_Transform( font, NULL, &pen ); FT_UInt index = FT_Get_Char_Index(font, c); if ( index == 0 ) { ZLOG_CRIT("char " << c << " index is zero"); continue; } error = FT_Load_Glyph(font, index, FT_LOAD_RENDER | FT_RENDER_MODE_NORMAL ); if ( error ) { ZLOG_CRIT("error " << error << " loading char " << c ); continue; } slot = font->glyph; if (c != ' ' ) draw_char( &slot->bitmap, slot->bitmap_left, m_height - slot->bitmap_top, color); pen.x += slot->advance.x; } |
