I think you are being too general in your reply. Of course it is possible to interpret embedded fonts that use custom mappings. If he creates a mapping for each font that maps the characters to the ascii character that corresponds to the letter drawn by each glyph. It's a simple substitution cypher where he can easily obtain the mapping by creating a pdf that displays all glyphs that he is interested in.
The downside is that you need to create the mapping for each font. /Klas 1T3XT info skrev 20:59: > On 6/09/2010 18:09, elyesl wrote: >> Now I don’t understand why would any tool (developer) associate ASCII >> characters with different glyphs. > > You should learn more about PDF instead of making assumptions. > >> Whatever the reason, we thought that it >> would be possible to use an API to interpret the mixed character/glyph >> mapping and continue to use the same code > > No, as Leonard rightly pointed out from the start: > OCR is your only option. > >> (since all the PDF readers still can). > > This allegation in contradiction with what you said earlier: > "But when parsing using iText, only strange characters appear. > Same behavior/result when copying the text to the clipboard and > pasting to notepad." > > PDF Readers CAN'T INTERPRET the characters correctly!!! > Pdf Reader can map a character to the code to draw a glyph > that is present in the font program embedded in the PDF. > > But if they see "moveTo x, y, curveTo x, y, lineTo x,y,...", > they can't tell you if this syntax represents an a, b, c, or > any other character. > >> We must be missing something but we figure out a workaround for now. > > The information you have received was very detailed. > We're very sorry that our efforts trying to explain the problem > weren't well received. > > ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
