Encoder and Decoder Tool for Evaluation of ARM Adaptive Scalable Texture Compression (ASTC)

The ASTC Evaluation Codec is a command-line executable that compresses and decompresses images using this texture compression standard.

Running on a standard PC, this tool allows content developers to evaluate the impressive quality and size benefits offered by this texture compression format, in advance of it being available in GPU  hardware.

 

ASTC FEATURES & BENEFITS

Encoding

  • Compression of PNG, TGA and KTX into ASTC format
  • Control of bit rate from 0.89 bits/pixel upto 8bits/pixel in fine steps
  • Control of compression time/quality tradeoff with exhaustive, thorough, medium, fast and very fast encoding speeds
  • Supports both low (LDR) and high dynamic range (HDR) images
  • Supports 3D texture compression
  • Measure PSNR between input and output

Decoding

  • Decodes ASTC images to TGA or KTX

Package Contents

  • Source code
  • Full specification of the ASTC data format
  • Binaries for Windows, Mac OS X and Linux (x86, 32-bit)
