I need to extect text from pdf with custom fonts but custom don't let to copy/paste text or search text or extract text in a clear/readble way by iText lib... the resultant text is space or non uman readable chars
The pdf format are: Author: User Creator: Compart Docponent API Producer: Compart MFFPDF I/O Filter 2013-03-09 00:51:11 CreationDate: 04/21/16 11:26:59 ModDate: 06/09/16 10:02:16 Tagged: no Form: none Pages: 6 Encrypted: no Page size: 595.2 x 841.92 pts (A4) (rotated 0 degrees) File size: 312703 bytes Optimized: yes PDF version: 1.4
the pdf fonts info are (running pdffonts command line for each fonts): name:[none] ; type:[Type 3] ; emb: [yes]; sub: [no]; uni : [yes];
so the pdf seems to have a ToUnicode map but that is not enough..
How I can read text in a clear way?
thanks in advance
