| enum SkFont::Flags |
| Enumerator | |
|---|---|
| kEnableAutoHints_Flag |
Use the system's automatic hinting mechanism to hint the typeface. This is a last resort hinting method applied only if other hinting methods do not apply. TODO: where to put auto-normal vs auto-light? |
| kEnableByteCodeHints_Flag |
If the typeface contains explicit bytecodes for hinting, use them. If both bytecode and auto hints are specified, attempt to use the bytecodes first; if that fails (e.g. there are no codes), then attempt to autohint. |
| kEmbeddedBitmaps_Flag |
If the typeface contains explicit bitmaps for hinting, use them. If both bytecode and auto hints are also specified, attempt to use the bitmaps first; if that fails (e.g. there are no bitmaps), then attempt to bytecode or autohint. |
| kUseNonlinearMetrics_Flag |
Use rounded metric values (e.g. advance). If either auto or bytecode hinting was used, apply those results to the metrics of the glyphs as well. If no hinting was applied, the metrics will just be rounded to the nearest integer. This applies to calls that return metrics (e.g. measureText) and to drawing the glyphs (see SkCanvas drawText and drawPosText). |
Return a font with the same attributes of this font, but with the specified size.
If size is not supported (e.g. <= 0 or non-finite) NULL will be returned.
