ZINC – bitmap mask problem solution
When using bitmaps to mask projectors in Zinc on OSX – bitmaps created on a Mac don’t load into the Zinc application – Zinc grays them out so making it impossible to export a masked projector.
Save a 24 bit .bmp file from Photoshop
Transfer the file to Windows
Transfer the bitmap back onto the Mac
Zinc should now pick it up okay in Finder.
