Thanks in xadvance!On lines 27 and 28, you see how I apply the offset. size is the pixel size of the font (note that I "normalize" the metrics by dividing by pixel size in the first place).This is how I render text at the moment (no kerning yet). (Additional question: is width, height, xadvance, yadvance, xoffset and yoffset all metrics I need to render text?)I have tried to use face->glyph->bitmap_left (and bitmap_top), and also face->glyph->metrics.horiBearingX / 64.0f (and Y), but the results always look arbitrary:// Set offset of glyphs accessing face->glyph here.Hi!I'm trying to render text, using FreeType 2. My problem is in offsetting each glyph with respect to their own origin. In this mail, with "offset", I refer to what is called bearingX and bearingY in this illustration.I first render all glyphs, storing necessary metrics, then use the results to render text.Given an unsigned char c, this is how I render glyphs, and need to obtain the correct offsets (C++):
FT_Face face;
if (!FT_Load_Char(face, c, 0)) {
if (!FT_Render_Glyph(face->glyph, FT_RENDER_MODE_NORMAL)) {
if (!FT_Get_Char_Index( face, c )) continue;
