CID fonts are not hinted, as they include no charmap and the auto-hinter |

- CHANGES TO THE RENDERER MODULES |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
the monochrome and smooth renderers are now in two distinct directories, |
|
|
|
|
namely "src/raster1" and "src/smooth". Note that the old "src/renderer" |
|
|
|
|
is now gone.. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
I ditched the 5-gray-levels renderers. Basically, it involved a simple |
|
|
|
|
#define toggle in 'src/raster1/ftraster.c' |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
FT_Render_Glyph, FT_Outline_Render & FT_Outline_Get_Bitmap now select |
|
|
|
|
the best renderer available, depending on render mode. If the current |
|
|
|
|
renderer for a given glyph image format isn't capable of supporting |
|
|
|
|
the render mode, another one will be found in the library's list. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
This means that client applications do not need to switch or set the |
|
|
|
|
renderers themselves (as in the latest change), they'll get what they |
|
|
|
|
want automatically... At last.. |
