I called *FT_Set_Pixel_Sizes(face, 40, 20); *hoping to get a glyph of 20x40
dimension in pixels, but when I used *face->glyph->bitmap *to access the
bitmap, its dimension is 26*14
Below is my code:
* FT_Library library;*
* if (FT_Init_FreeType(&library) != FT_Err_Ok) throw runtime_error("Failed
to load freetype library");*
* FT_Face face;*
* if (FT_New_Memory_Face(library, fontData, fontDataSize, faceIndex, &face)
!= FT_Err_Ok) throw runtime_error("Failed to load face from font file");*
* FT_Set_Pixel_Sizes(face, 40, 20);*
* int glyphIndex = FT_Get_Char_Index(face, 65); // 65 is 'A'*
* if (glyphIndex == 0) throw runtime_error("Character doesn't exist in
font");*
* FT_Load_Glyph(face, glyphIndex, FT_LOAD_DEFAULT);*
* if (face->glyph->format != FT_GLYPH_FORMAT_BITMAP)*
* FT_Render_Glyph(face->glyph, FT_RENDER_MODE_NORMAL);*
* FT_Bitmap bitmap = face->glyph->bitmap;*
* cout<<bitmap.rows<<' '<<bitmap.width<<endl;*
