I have a large sample of .WI images I need to convert to e.g. JPEGs, but the format now seems defunct.
The mimetype is image/wavelet.
The compression algorithm was developed by Summus, a US company that also now seems defunct.
The last CorelDraw support for the format was under 32-bit Windows (see https://community.coreldraw.com/talk/coreldraw_graphics_suite_x6/f/corel-photo-paint-x6/33558/is-wi-supported-in-x). If I go down the hardware route I need to be able to make calls to a server via e.g. REST.
I think under *nix djvulibre might be able to open the files, but I haven't been able to test this yet. Also IrfanView.
Another option is to re-implement the codec myself.
Does anyone here have any expertise in this area?
Apologies if this is not the right forum - is there a better place?
Thanks for all help!
Here's an input sample http://www.wolfgang-rolke.de/graphics/wavelet.wi
