#RetroComputing tool alert!
#deark is a great little utility for extracting information from old files.
In the #Psion world, it will extract resources (such as pictures) from .APP and .OPA/OPO files, and it will convert three-colour .PIC files to PNG!
It also handles #Acorn sprites, #Amiga icons, #MacPaint, #PalmOS bitmaps, #WMF...
It compiles on Windows, #Linux, macOS and #BSD. And, as of about 5 minutes ago, there's a #HaikuOS recipe in HaikuPorts. 'Cos I made it.
