Routine Description:
|
||
|
|
Translates a Unicode character into the corresponding font glyph.
|
||
|
|
If the Source was pointing to a non-spacing character, the next Source[*Index]
|
||
|
|
character will be parsed and OR'd to the GlyphBuffer until a spacing character
|
||
|
|
is found in the Source. Since non-spacing characters are considered to be the
|
||
|
|
same pixel width as a regular character their BitWidth will be reflected correctly
|
||
|
|
however due to their special attribute, they are considered to be zero advancing width.
|
||
|
|
This basically means that the cursor would not advance, thus the character that follows
|
||
|
|
it would overlay the non-spacing character. The Index is modified to reflect both the
|
||
|
|
incoming array entry into the Source string but also the outgoing array entry after having
|
||
|
|
parsed the equivalent of a single Glyph's worth of data.
