![]() I overlap both to give a better idea of comparison. On the right side we have Hold! rendered and for the most part is consistent with the render. On the left, we have World! rendered, and the orld! is correctly placed, but the distance between W and o is too large now compared to the correct rendering. My render: I include the advance placements (red) and the starting position (yellow). So here are some rendering comparisons line by line:Ĭorrect render: Here are two different strings left and right, correctly rendered through I am using this Zapfino font, because it seems fairly complex and a good metric to test if things are rendering correctly. Maybe someone can shed some light, but I am not sure where to start.įrom my basic interpretation the font layout is composed of rendering the glyphs as lsb + width, and then the place to put the next character is called the advance and the advance width is composed of lsb, glyph width, rsb. While 99% of tests I have done seem to work, I am running into inconsistent spacing and I have no idea what is causing it. ![]() I am rendering each glyph using ID2D1RenderTarget.DrawTextLayout with WIC bitmaps. I am using DirectWrite with a IDWriteFontFace and using the GetGlyphIndices with GetDesignGlyphMetrics to get the metrics of the glyphs so I can take each glyph, store it as an image, then reconstruct the whole string using the glyph information (advance, lsb, rsb, etc). I am running into inconsistencies with how glyphs are spaced in some situations.
