Hello,
I finally raped your code to achieve my end!
Into PDTrueTypeFont.java I have force the mapping of width to use the
choosen encoding:
Encoding e =
EncodingManager.INSTANCE.getEncoding(COSName.WIN_ANSI_ENCODING);
for( int i=0; i<widthValues.length ; i++ )
{
if(glyphToCCode[i]-firstChar < widths.size() &&
glyphToCCode[i]-firstChar >= 0
&& widths.get( glyphToCCode[i]-firstChar) == zero )
{
try {
widths.set( e.getCode(e.getNameFromCharacter(
(new StringBuilder()).appendCodePoint(
glyphToCCode[i]).toString().toCharArray()[0])),
widthValues[i]*scaling );
} catch (IOException x) {
widths.set( glyphToCCode[i]-firstChar,
widthValues[i]*scaling );
}
}
}
Then widths seems correct now.
Just notice that firstChar is hard coded to 0 in the original code, so I
think that you can remove it from.

Kévin
