Create a PDF file on an SD card ?

pdfnow · Guest

I can read/write to sd cards using a PIC18f2620. Does anyone think there is a way to create a simple pdf file on the card with text only. If the use want to save a file with Hello World on the first line, what would the pdf file look like? Could it be created with CCS C and fit on a 18F2620? Thanks.

I don't think there is an easy way to create a pdf file using just text. You'd have to understand different parts of a PDF, which, IMHO, is not an easy task. PDFs are based on the PostScript language, and 'carry' with themselves several formatting options, images, strings, etc. Infact, a PDF is more like a script file, rather than a simple 'document'. This 'script file' like behaviour is what makes it platform independent.

I have in the past made a pdf template, then did a replace at specific byte locations to put my own text. Open a pdf in a hex editor, find the locations, that might help.

Other than that, look for some php source on creating pdf's.
