GimpFormats

Project Icon

Forked from https://github.com/TheHeadlessSourceMan/gimpFormats

A pure python implementation of the GIMP XCF image format. Use this to interact with GIMP image formats

Issues and contributions very much wanted/ needed :smile:

Previously under gimpformats_unofficial now under gimpformats

Getting started

Read an image

from gimpformats.gimpXcfDocument import GimpDocument
project = GimpDocument("image.xcf")

Iterate the image and report the contents of each group followed by the first level children of the image

"""List data on groups followed by the direct children of a gimp xcf document
"""
layers = project.layers
index = 0
print("## Group info...")
while index < len(layers):
	layerOrGroup = layers[index]
	if layerOrGroup.isGroup:
		index += 1
		while layers[index].itemPath is not None:
			print("Group \"" + layerOrGroup.name + "\" contains Layer \"" + layers[index].name + "\"")
			layers.pop(index)
	else:
		index += 1

print("## Document direct children...")
for layerOrGroup in layers:
	print("\"" + layerOrGroup.name + "\" is a " + ("Group" if layerOrGroup.isGroup else "Layer"))

Example output:

## Group info...
Group "Layer Group" contains Layer "Layer"
Group "Layer Group" contains Layer "Layer2"
## Document direct children...
"bg #1" is a Layer
"bg" is a Layer
"bg #2" is a Layer
"Transformation" is a Layer
"Layer Group" is a Group
"Background" is a Layer

Next tasks (see below)

  • Saving

Currently supports

  • Loading xcf files (up to current GIMP version 2.10)
  • Getting image hierarchy and info
  • Getting image for each layer (PIL image)
  • .gbr brushes
  • .vbr brushes
  • .gpl palette files
  • .pat pattern files
  • .gtp tool presets
  • Generate a flattened image
  • Add new layers

In progress but results in crashes and tests failing

  • Saving
  • .ggr gradients - reads/saves fine, but I need to come up with a way to get the actual colours
  • .gih brush sets - BUG: seems to have more image data per brush than what's expected
  • .gpb brush - should work, but I need some test files

Not implemented

  • Exported paths in .svg format. - Reading should be easy enough, but I need to ensure I don't get a full-blown svg in the mix
  • Standard "parasites"
