    asie got a reaction from Fingercomp in Nadeshicodec - 320x200 OC video encoder

    Apologies for scarce documentation, it's a bit of a project dump. It has a GUI, however. Feel free to fork and clean it up with the terms of the license in mind.

    asie got a reaction from Fingercomp in pngview - High-resolution .PNG viewer in OpenComputers   
    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.

    I've spent a fair amount of time trying to get the maximum image quality out of OpenComputers. It all began with BTM15's quick need for a presentation tool, giving us 160x100 at 256 colors - not a huge accomplishment, but a start. BTM16 later brought us 320x100 with adaptive palettes - better, but still not quite there.
     
    Recently, I have started working on it again, and thanks to a mini-competition between me and GreaseMonkey I managed to arrive at something rather high quality - the ChenThread Image Format, complete with its own CTIFConverter. It is 320x200, thanks to the new font's block-based nature of the Braille area of Unicode. (It also supports a 160x100 @ 16 color mode for OpenComputers' Tier 2 mode.)
     
    The converter, source code and reference viewer is available here. Keep in mind that, as this is a reference viewer, it will not be as fast as it could be - it does no GPU call optimizations whatsoever beyond the simplest ones. I will try to release a better version later.
     
    Here's an example of the quality you can get out of this:

    Amazing! Must be the most epic image lib for OC =)
