 When a file is compressed using PKZIP, a decompression program, is required to expand the file. An option in PKZIP allows a simple version of an unzip program to be bundled with each compressed file. Choosing this option creates an executable file that expands automatically to the original file, avoiding the issue of whether the recipient of a compressed file will have the appropriate decompression software. I made a tga that contains its own image rendering code. 11 comments

@neauoire there’s a format called flic that, according to email correspondence i had with its creator peter kennard, was the inspiration for “tagged” binary formats (iff, riff, tiff, png, avi, ico, etc) (allthough the timing for that claim doesn’t quite line up) the format itself is effectively very similar to animated gif, with optimisations for smooth playback on low end devices with very low memory and disk bandwidth.

 @neauoire yeah, I had so much fun with that in the 90s. There was a windows app that could add different actions kind of like an animated powerpoint. Then came the malware guys and then it was blocked in all virus scanners. |
