Hi Guys,
I have a project to manage documents. The app has its own scanner manager (ole/Wia), which could also create pdf files based on bmp/jpg conversion. I am also able to implement a textual report renderer to write pdfs.
Unfortunately, I have other pdf files which were not generated by my app. So, I would like to parse it for some reasons.
In my understanding the PdfDraw can only render pdf format (see PdfDraw::Finish() function),
but it is not able to read/load/parse a pdf file. Am I right ?
Is it a project on-going development somewhere to have this feature for U++ ?
My actual goal would be,
- load an external pdf file, parse it some level
- to check the signature(s), add a signature to an ordinary pdf file.
- render one static view (in example ctrl::paint(draw&) way would be fine)
- in case of image is encoded into the pdf, that is not a problem for my use-case.
- in case of vector graph/text content is in pdf, some kind of graphical render is needed.
- to be able to display pdf files on linux, windows and maybe with Turtle later.
