Hi,
I tried to have GetHasGlyphs working and went through several issues :
* how a BFont is identified server side : should there be a ServerFont
object for every BFont ? If not, a lot of BFont properties have to be
sent server side for most FT computations. Is this the way to go ?
* BFont is using a Encoding()/SetEncoding() scheme, which makes me think
methods can accept character string in a non utf8 encoding. What are we
supposed to do ? (convert_to_utf8 client side, server side, let FT know
the encoding and handle) (the last point implies we pass a complete
character string to FT)
* ServerFont is sometimes implemented with this kind of code, which is
wrong :
for (int i = 0; i < numChars; i++) {
...
FT_Load_Char(face, charArray[i], FT_LOAD_NO_BITMAP);
}
nth char of charArray isn't charArray[i]. I would go with a
next_utf8_char() if we were sure about the UTF8 encoding.
* GetHasGlyphs needs to know when a glyph is available for a character :
do I have to call FT_Load_Char(face, charArray[i], FT_LOAD_NO_BITMAP);
and check for the return value ?
Bye,
Jérôme
