Reverse engineering of the CorelDRAW file formats
CorelDRAW uses its own proprietary file formats.
That is claimed to have poor compatibility between different versions of formats and CorelDRAW editor itself.
On the first stage of CDR format research I made a utility to extract preview image from CDR files.
After that together with sK1 Team we conducted CDR format research, added importer
to sK1 vector graphics editor and released universal
convertor with support for CDR/CMX/CDRX/CDT/CCX file formats version 7 to X3.
So far this importer supports Bezier curves, strokes and outlines. We already found enough data to
add support for gradient fills and embedded bitmaps. It will be added in the next sK1 editor release.
