| 18:30 | <&McMartin> | abudhabi_: The early Amigas do not have proper support for icon creation, so I had to write a little program to generate the icons I awnted |
| 18:30 | <&McMartin> | Then I thought "I should just link in a PNG reading library so that I can code-generate those icon-makers without having to go through some very dumb extra steps" |
| 18:30 | <&McMartin> | Then I thought "I wonder if that PNG library will actually run on the target machine" |
| 18:30 | <&McMartin> | And it does! |
| 18:31 | <&McMartin> | What you're looking at is a PNG being read, reduced to four colors, and then printed out as text on the console screen, with the icon version of it on the side for reference. |
| 18:31 | < abudhabi_> | I see. |
| 18:31 | < abudhabi_> | Thank you. |
| 18:33 | <&McMartin> | The two aren't linked; you're seeing the PoC text-dumper and the prebuilt reference icon, and I have a bit of work left to bridge that gap and also to make it notice if it's going to crash the system when you run it |
| 18:33 | <&McMartin> | (Which it does if you leave the command shell at its default settings) |
| 20:47 | <@TheWatcher> | Can I just note that I find that somehow deeply hilarious that you're reading and writing pngs on a computer that predates the invention of the format by a decade |
| 21:05 | <&McMartin> | That's definitely part of the joy here |
| 21:05 | <&McMartin> | Also why it took three takes to realize that it was worth attempting |
| 21:05 | <&McMartin> | (And going even further out: the compiler I'm using here implements all the important parts of C99, so I get to use stuff like stdint.h that were Very Not Available in 1987) |
| 21:06 | <&McMartin> | (... of course, in 1987, *function prototypes* were not available...) |
| 21:08 | <&McMartin> | It was both reassuring and deeply alarming to see the sudden and absolutely drastic collapse in coding standards in the type-ins, sometimes within the same book, when switching from BASIC to C |
| 21:18 | <&McMartin> | That said: only reading PNGs. Writing .info files. |
| 21:19 | <&McMartin> | The whole point here was to turn a deeply bizarre four-step process of turning my PNGs from a proper paint program into an actual usable icon into a two-step process of "make icon in paint program and export as PNG" and then "run this program on it on the Amiga" |
