Make texture using full or half transparent pixels

Introduction

Minecraft Dungeons is known to use textures with invisible or half-visible pixels. This can be an issue when your software does not allow you to save pixels with their alpha value set to 0. There are a bunch of handy scripts to help you making these tricky textures!

Sources

All scripts are available here. If you find any bugs, please make a issue on the GitHub repository.

Requirements

• Pillow is required to use those programs!

 python3 -m pip install --upgrade pip
 python3 -m pip install --upgrade Pillow

Scripts

• remove_alpha.py
  
  

  From Alpha to Opaque.

  Set all pixels opaque.

  • Use BASE_remove_alpha.png as base.
  • Return RESULT_remove_alpha.png.


• get_alpha.py
  
  

  From Opaque to Alpha.

  Set all pixels transparent.

  • Use BASE_get_alpha.png as base.
  • Return RESULT_get_alpha.png.


• merge_alpha_layers.py
  
  

  Merge both types easily.

  With this one, you have to set two "masks": one with opaque pixels and one with transparent pixels.

  • Use BASE_merge_alpha_layer0.png as base for solid pixels.
  • Use BASE_merge_alpha_layer1.png as base for transparent pixels.
  • Return RESULT_merge_alpha.png.
