A command-line tool and Python library to automatically generate new textures similar to a source image or photograph. It's useful in the context of computer graphics if you want to make variations on a theme or expand the size of an existing texture.

This software is powered by deep learning technology — using a combination of convolution networks and example-based optimization to synthesize images. We're building texturize as the highest-quality open source library available!

The examples are available as notebooks, and you can run them directly in-browser thanks to Jupyter and Google Colab:

• Gravel — online demo and source notebook.

Generate variations of any shape from a single texture.

Usage:
    texturize remix SOURCE...

Examples:
    texturize remix samples/grass.webp --size=720x360
    texturize remix samples/gravel.png --size=512x512

from texturize import api, commands, io

# The input could be any PIL Image in RGB mode.
image = io.load_image_from_file("examples/dirt1.webp")

# Coarse-to-fine synthesis runs one octave at a time.
remix = commands.Remix(image)
for result in api.process_octaves(remix, size=(512,512), octaves=5):
    pass

# The output can be saved in any PIL-supported format.
result.images[0].save("output.png")

Reproduce an original texture in the style of another.

Usage:
    texturize remake TARGET [like] SOURCE

Examples:
    texturize remake samples/grass1.webp like samples/grass2.webp
    texturize remake samples/gravel1.png like samples/gravel2.png --weight 0.5

from texturize import api, commands

# The input could be any PIL Image in RGB mode.
target = io.load_image_from_file("examples/dirt1.webp")
source = io.load_image_from_file("examples/dirt2.webp")

# Only process one octave to retain photo-realistic output.
remake = commands.Remake(target, source)
for result in api.process_octaves(remake, size=(512,512), octaves=1):
    pass

# The output can be saved in any PIL-supported format.
result.images[0].save("output.png")

Combine multiple textures together into one output.

Usage:
    texturize mashup SOURCE...

Examples:
    texturize mashup samples/grass1.webp samples/grass2.webp
    texturize mashup samples/gravel1.png samples/gravel2.png

from texturize import api, commands

# The input could be any PIL Image in RGB mode.
sources = [
    io.load_image_from_file("examples/dirt1.webp"),
    io.load_image_from_file("examples/dirt2.webp"),
]

# Only process one octave to retain photo-realistic output.
mashup = commands.Mashup(sources)
for result in api.process_octaves(mashup, size=(512,512), octaves=5):
    pass

# The output can be saved in any PIL-supported format.
result.images[0].save("output.png")

Increase the resolution or quality of a texture using another as an example.

Usage:
    texturize enhance TARGET [with] SOURCE --zoom=ZOOM

Examples:
    texturize enhance samples/grass1.webp with samples/grass2.webp --zoom=2
    texturize enhance samples/gravel1.png with samples/gravel2.png --zoom=4

from texturize import api, commands

# The input could be any PIL Image in RGB mode.
target = io.load_image_from_file("examples/dirt1.webp")
source = io.load_image_from_file("examples/dirt2.webp")

# Only process one octave to retain photo-realistic output.
enhance = commands.Enhance(target, source, zoom=2)
for result in api.process_octaves(enhance, size=(512,512), octaves=2):
    pass

# The output can be saved in any PIL-supported format.
result.images[0].save("output.png")

For details about the command-line usage of the tool, see the tool itself:

texturize --help

Here are the command-line options currently available, which apply to most of the commands above:

Options:
    SOURCE                  Path to source image to use as texture.
    -s WxH, --size=WxH      Output resolution as WIDTHxHEIGHT. [default: 640x480]
    -o FILE, --output=FILE  Filename for saving the result, includes format variables.
                            [default: {command}_{source}{variation}.png]

    --weights=WEIGHTS       Comma-separated list of blend weights. [default: 1.0]
    --zoom=ZOOM             Integer zoom factor for enhancing. [default: 2]

    --variations=V          Number of images to generate at same time. [default: 1]
    --seed=SEED             Configure the random number generation.
    --mode=MODE             Either "patch" or "gram" to manually specify critics.
    --octaves=O             Number of octaves to process. Defaults to 5 for 512x512, or
                            4 for 256x256 equivalent pixel count.
    --quality=Q             Quality for optimization, higher is better. [default: 5]
    --device=DEVICE         Hardware to use, either "cpu" or "cuda".
    --precision=PRECISION   Floating-point format to use, "float16" or "float32".
    --quiet                 Suppress any messages going to stdout.
    --verbose               Display more information on stdout.
    -h, --help              Show this message.

We suggest using Miniconda 3.x to manage your Python environments. Once the conda command-line size is installed on your machine, there are setup scripts you can download directly from the repository:

# a) Use this if you have an *Nvidia GPU only*.
curl -s https://raw.githubusercontent.com/texturedesign/texturize/master/tasks/setup-cuda.yml -o setup.yml

# b) Fallback if you just want to run on CPU.
curl -s https://raw.githubusercontent.com/texturedesign/texturize/master/tasks/setup-cpu.yml -o setup.yml

Now you can create a fresh Conda environment for texture synthesis:

conda env create -n myenv -f setup.yml
conda activate myenv

NOTE: Any version of CUDA is suitable to run texturize as long as PyTorch is working. See the official PyTorch installation guide for alternatives ways to install the pytorch library.

Then, you can fetch the latest version of the library from the Python Package Index (PyPI) using the following command:

pip install texturize

Finally, you can check if everything worked by calling the command-line script:

texturize --help

You can use conda env remove -n myenv to delete the virtual environment once you are done.

If you're a developer and want to install the library locally, start by cloning the repository to your local disk:

git clone https://github.com/texturedesign/texturize.git

We also recommend using Miniconda 3.x for development. You can set up a new virtual environment called myenv by running the following commands, depending whether you want to run on CPU or GPU (via CUDA). For advanced setups like specifying which CUDA version to use, see the official PyTorch installation guide.

cd texturize

# a) Use this if you have an *Nvidia GPU only*.
conda env create -n myenv -f tasks/setup-cuda.yml

# b) Fallback if you just want to run on CPU.
conda env create -n myenv -f tasks/setup-cpu.yml

Once the virtual environment is created, you can activate it and finish the setup of texturize with these commands:

conda activate myenv
poetry install

Finally, you can check if everything worked by calling the script:

texturize --help

Use conda env remove -n myenv to remove the virtual environment once you are done.
