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 the new ARM ASTC texture compression standard.

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

 

FEATURES & BENEFITS

ASTC 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

ASTC 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)
