asie 28 Posted June 30, 2018 Share Posted June 30, 2018 Those of you who have followed my OpenComputers work might be aware of CTIF, my high-quality image converter for OpenComputers. However, it has always required an external converter to pre-process image files. Others may be aware of greaser's ocpng, an utility-turned-library for displaying regular PNG files without pre-processing - however, that capped out at 160x50 as it only used low-resolution characters. However, I am proud to present pngview - a .PNG viewer right in OpenComputers, based off greaser's ocpng library but capable of displaying images at up to 320x200. Unfortunately, it does not display images as well as CTIF - it has far more severe limitations related to being a simple Lua script that, as such, cannot perform calculations that complex. In particular, it handles slowly changing gradients a lot worse and is incapable of finding additional colors to supplement the image's palette the way CTIF does. Comparison: the top image is viewed via pngview, the bottom image is rendered via CTIF. Known issues: Currently, it only works on Tier 3, as the palette calculation process relies primarily on the 240 RGB colors exclusive to it. It does not perform any image scaling, so ~320x200 is the maximum image size (on Tier 3). Downloads: pngview is part of a Lua script collection called octagon.
