SLK_img2pixel 1.3

SLK_img2pixel v1.3 has been released! The update contains features/fixes that have accumulated since the last release, more than half a year ago (heh).

Persistent file/folder paths

When selecting files, SLK_img2pixel will now remember the last path. Every file dialog remembers an individual path, so you don’t have to navigate the filesystem every time you want to save/load a image/palette/preset.

k-means color selection

I’ve experimented with using the color quantization algorithm for asining palette colors to an image. It works quite well for low contrast images, here are a few comparisons (all done with default settings and SLSO8 palette):

The option can be found in the Colors tab, as a new mode to the dist selection. The slider below it controls how important the palette colors should be in the distribution (1 - very important, 16 - nearly ignored).

QOI format

Recently this new, simple image format has become quite popular. I added support for both reading and writing files in the QOI format. For other software supporting it, look here (not a comprehensive list): https://github.com/phoboslab/qoi#qoi-support-in-other-software

Full change log:

• added persistent paths for file/folder selection
• added K-means color distance mode
• made empty tabs in gui unclickable
• Options in the gui are now only shown if they actually do anything
• added support for qoi format
• removed supersampling sample mode (virtually the same results can be achieved using a high gauss blurring setting)
• removed gif processing (it was basically useless anyway)
• fixed multiple memory leaks
• fixed hue adjustment discarding alpha
