img2texture
Command line utility for converting images to seamless tiles.
The resulting tiles can be used as textures in games, compositing and 3D modeling applications, etc.
Sample images
:warning: If images don't load, check out the original of this document on GitHub.
Original image x4
Orion galaxy by NASA/ESA, in four copies side by side.
We cannot use the original image as an endless space background: the seams are visible.
Converted image x4
The result of img2texture, in four copies side by side.
The image is slightly reduced in size and the edges are modified with
alpha-blending.
Seams no longer appear when merging. The converted image can be tiled and panned in any
direction. It will feel endless and seamless.
Install
$ pip3 install img2texture
Run
Create new seamless.jpg from source.jpg.
$ img2texture /path/to/source.jpg /path/to/seamless.jpg
--overlap
The --overlap option determines how much of the image will be used to hide the seams.
For example, the following command uses 25% of the width and 25% of the height
of the original image:
$ img2texture source.jpg seamless.jpg --overlap 0.25
Increasing the value makes the seam less visible. However, the image becomes smaller.
Sample images
:warning: If images don't load, check out the original of this document on GitHub.
--overlap 0.05
The 5% seam.
--overlap 0.4
The 40% seam.
--tile
The --tile option will create a 2x2 tiled version in addition to the converted image.
The following command will create seamless.jpg and seamless_2x2.jpg.
$ img2texture source.jpg seamless.jpg --tile
All the samples on this page were created with --tile.
