zTextureReducer

An image processing utility, to plan modifications ahead and then batch execute them, written in Python 3

Supported features

• resizing
• recoloring
  • 256 colors
  • 16 colors
  • greyscale
• dithering
• keeping / discarding alpha channel
• renaming files on export

Installation

Python 3 should be installed on your system with pip

Windows

use the files in win directory to avoid using a command prompt

• install.bat -> install dependancy (still need a proper installation of python 3)
• launch.bat -> launch the software

CLI

Get this repository Launch command prompt, go to this directory, then

$> python -m pip install --user -r requirements.txt
$> python main.py

• Tested on Windows 7 with Python 3.6

TODO

• Activate the big export button
• Zoom on preview (by rescaling with NEAREST)
• Add requirements.txt to pip install dependency easily
• win/*.bat files for windows users to easily install dependency and use it.
• Delete queue after export
• Export confirmation (success / error)
• Renaming options for export
  • 1/2 Queue option to rename
  • 2/2 implementation in export
• Alpha preservation during processing
• Better alpha support
  • Bi Level Alpha support
  • Alpha options
  • Discard
  • Bi level
  • 255 level
  • Own resize & dither
• Does dithering really work ?
  • If not, should consider adding PIL.Image.quantize function to the stack of operations (wasn't working indeed)
  • Does the outputted color numbers is correct ? (dither = duplication of one color) (quantize after dithering)
  • grayscale & dithering support
• Better quantization support
  • different parameters exposed
  • better alpha handling
• Support different color format
  • RGBA5551
  • ia16 (8 bits greyscale 8 bits alpha)
  • ...
