Hello All,
I'm working in embedded domain and trying to generate a pdf report dynamically. There is a code space concern in my embedded module so I was unable to use open source library like libharu etc.
The following procedure I have used to generate a pdf.
First I created a txt file having basic pdf header,trailer and xref and then I have modified length and data stream fields( feeding my data to data stream). Later the txt file is saving/converting as .pdf.
First issue faced: There are some special characters required for Italian and french language pdf. After I changed encoding to WinAnsiEncoding that issue got solved.
second issue: But currently I'm try to generate a pdf for Russian and Greek using same approach using CP1251 or other some encoding standards. the generated PDF is taking standard encoding by default. Can any one help me how can i generate pdf for Russian and Greek Languages.
Thanks in advance,
Jins.
