Compatibility

Bear in mind that the tables below may not be completely accurate. If that is the case, please open an issue and I will fix the tables.

Overview

Key

• :heavy_check_mark: - Supported
• :warning: - Things will look the same, but data is lost
• :x: - This is not supported and will cause loss of data
• N/A - The source format does not support this so treat this as a :heavy_check_mark:

Layers are rasterized before being written to TIFF/ GIF or WEBP
First child layers are placed in a group when written to LSR

.layered

.layered is highly inspired by the open raster format and aims to provide an exchange format in the cases when saving in ora would cause unacceptable data loss. .layered has been designed so that if the format became deprecated and no readers existed for it tomorrow, the data would be easily salvageable.

See the LAYERED_SPEC for more information.

Docs

See the Docs for more information.

Example Usage

Here's some basic example usage below.

"""Example module """
from pathlib import Path
THISDIR = str(Path(__file__).resolve().parent)
import layeredimage.io

# Do stuff
ora = layeredimage.io.openLayerImage(THISDIR + "/image.ora")

imageDimensions = ora.dimensions
# There are a load of handy functions for getting layers, and adding new
# layers, but here we will act directly on the object
layer = ora.layersAndGroups[0] # For the sake of the e.g. this is a layer

# Lets overwrite the layer with a transparent image (bit boring I know...)
layer.image = Image.new("RGBA", imageDimensions)
ora.layersAndGroups[0] = layer

# And let's save
layeredimage.io.saveLayerImage(THISDIR + "/image(modified).ora", ora)

# Let's save a flattened version too
ora.getFlattenLayers().save(THISDIR + "/image(modified).png")

# Doing stuff with a group
group = ora.getLayerOrGroup(1) # For the sake of the e.g. this is a group
group.layers[0].image.show() # Open the image of the first layer of the group

# Deleting a layer/ group
ora.removeLayerOrGroup(2)

Images are PIL.Image (s) and so you can use the power of Pillow to apply filters, and other modifications to the images.

See below for an old version of the tests. These provide a few examples of file conversions. Not going to get 100% coverage anytime soon but hopefully this will help a little.

"""Test module """
