An ASTC encoder exposed as a Web service

ASTC Encoder Service

This tool is meant to integrate your infrastructure and provide realtime resource (images, textures) conversion to the ASTC compressed data format.

The ASTC compressed data format, developed by Arm® and AMD, has been adopted as an official extension to the OpenGL®, OpenGL ES, and Vulkan® graphics APIs.

See the official repository for more information: https://github.com/ARM-software/astc-encoder

Principle

• Call the service and provide an image file (JPG, PNG, ...)
• The service returns the converted resource in the ASTC format

Parameters

• input_file: contains the input binary file (an image to convert); mandatory
• block_footprint: size of your block footprint (default: 6x6)
• mode: can be one of four choices (default which is the linear LDR color profile, sRGB, HDR1 tuned for HDR RGB and LDR A, HDR2 tuned for HDR RGBA)
• quality: can be fastest, fast, medium, thorough, exhaustive (default medium)

TODO

• API wrapper
• Dockerfile
• Default parameters

Limitations

This repository focuses on the x86_64 version of the ASTC encoder. If you wish to use another instructions set, have a look at the official releases available on the ARM-software/astc-encoder repository.

The service doesn't manage any queue because we don't need one, and it is recommended to deploy multiple instances in a cluster to handle a low or limited workload.
