Tools for manipulating pixel art sprites and tilesets.

1. Install miniconda

2. Clone and install repository

   git clone https://github.com/bluecarrot16/lpctools
   cd lpctools
   conda env create -f environment.yml
   conda activate lpctools
   pip install -e .
   

Easiest way to install dependencies is with conda as above. If you don't want to use conda, you can install the dependencies manually.

Current dependencies:

• pillow
• numpy
• pandas
• pytest (for unit tests)

Future versions will also depend on:

• pygame
• PyTMX

run lpctools --help, lpctools COMMAND --help, lpctools COMMAND SUBCOMMAND --help, etc. for more detailed usage

• lpctools arrange: organizes animation frames into spritesheets
  • lpctools arrange repack: re-arrange spritesheet
  • lpctools arrange distribute: takes small number of images, arranges them into full set of animations
  • lpctools arrange unpack: takes a spritesheet and slices it up into many individual images
  • lpctools arrange pack: takes many individual images and arranges into a spritesheet
• lpctools colors: manipulates palettes, recolors images
  • lpctools colors recolor: re-color image(s) with several palette(s)
  • lpctools colors convert-palette: convert color palettes between different formats
  • lpctools colors create-mapping: create a mapping between several color palettes
  • lpctools colors convert-mapping: convert a mapping between different formats

• Construct a full spritesheet of animations for several hairstyles:

   lpctools arrange distribute \
   --input tests/arrange_files/hair/hair_plain/ \
   --output tests/arrange_files/shield/hair_plain.png \
   --input tests/arrange_files/hair/hair_page2/ \
   --output tests/arrange_files/shield/hair_page2.png \
   --input tests/arrange_files/hair/hair_shoulderr/ \
   --output tests/arrange_files/shield/hair_shoulderr.png \
   --offsets tests/arrange_files/hair/reference_points_male.png \
   --mask tests/arrange_files/hair/masks_male.png

• Construct a full spritesheet of animations for the crusader shield:

   lpctools arrange distribute --input tests/arrange_files/shield/crusader/ --output tests/arrange_files/shield/crusader.png --offsets tests/arrange_files/shield/reference_points_male.png --mask tests/arrange_files/shield/masks_male.png

• Re-arrange images from one spritesheet layout to another:

   lpctools arrange repack --input tests/arrange_files/packed-evert.png --from evert --to universal

• Split one spritesheet into several spritesheets, one per animation (will create files arrange_files/_separated/{cast,walk,thrust,slash,shoot,hurt}.png):

   lpctools arrange separate --input tests/arrange_files/male.png --layout universal --output-dir tests/arrange_files/_separated

  • This can also be accomplished with repack; Split one spritesheet into several spritesheets, one per animation:

     lpctools arrange repack --input tests/arrange_files/packed-evert.png --from evert --to cast thrust walk slash shoot hurt grab push --output-dir tests/arrange_files/repacked

• Combine multiple spritesheets into one larger layout:

   lpctools arrange combine --input tests/arrange_files/repacked --layout universal --output tests/arrange_files/_combined.png

  • This can also be accomplished with repack; Split one spritesheet into several spritesheets, one per animation:

     lpctools arrange repack --input tests/arrange_files/repacked/{cast,thrust,walk,slash,shoot,hurt}.png --from cast thrust walk slash shoot hurt --to universal --output tests/arrange_files/_combined.png

• Recolor two hairstyles to two different palettes:

   lpctools colors -v recolor --input tests/recolor_files/hair.png tests/recolor_files/hair_page2.png --mapping tests/recolor_files/palettes.json

• Recolor a hairstyle to two different palettes, using a palette defined by an image:

   lpctools colors -v recolor --input tests/recolor_files/hair.png --mapping tests/recolor_files/map.png --palette-names blonde blue

• Recolor an image from one palette to another, with one palette defined by an image and another in a GIMP .gpl file:

   lpctools colors -v recolor --input tests/recolor_files/human_head.png --from tests/recolor_files/ivory.png --to tests/recolor_files/ogre.gpl

• Recolor all male "hair" images from the Universal LPC Spritesheet:

   $ git clone --shallow https://github.com/sanderfrenken/Universal-LPC-Spritesheet-Character-Generator
   $ time (lpctools colors recolor \
   	--input Universal-LPC-Spritesheet-Character-Generator/spritesheets/hair/male/*.png \
   	--mapping tests/recolor_files/all-palettes.json)
  
   real	1m18.583s
   user	1m6.450s
   sys	0m3.001s
