KTX-creator

KTX-creator can help you to compressing and packing images into a KTX texture. It supports automatic mipmaps generation and Adaptive Scalable Texture Compression (ASTC).

Submodules

You just need to initialize them.

git submodule init
git submodule update

ASTC encoder

ASTC encoding library [github]

LibKTX

Khronos KTX library [github]

ImageMagick

ImageMagick library with CMake support [github]

Catch2

Test framework for unit-tests [github]

Build

cmake -H. -Bbuild
cmake --build build

Usage

You can pack an image into a KTX (background.ktx) file by running:

ktx-creator background.png

Compression

You can specify the compression you want to apply on the image before packing it into a KTX file specifying -c <compression>. The following command will compress the png image using ASTC for you.

ktx-creator -c astc background.png

Mipmaps

You can tell ktx-creator to generate mipmaps by passing -mipmaps on the command line interface. This command, for example, will generate the mipmaps, will compress them, and will pack them into a KTX file.

ktx-creator -mipmaps -c astc background.png
