I need to output something into a .cdr (Corel Draw) file format. After some time searching, I can't find any useful information on the file format, and so far I haven't found a library that I can use. I would prefer the lib to be either C++ or python, but currently I'm desperate enough to just rewrite it from another language into one that suits me, if there is one available, or writing it from scratch if there isn't and I have the specification.
CDR format is supported by some non-Corel software.
I started to write my own CDR specification here: https://github.com/photopea/CDR-specification/ I believe it is the only public CDR specification that exists at the moment.
