Extension

This extension exposes the compressed texture format defined in the KHR_texture_compression_astc_hdr OpenGL ES extension to WebGL. Consult that extension specification for behavioral definitions, including error behaviors.

ASTC textures may be encoded using either high or low dynamic range, corresponding to an "HDR profile" and "LDR profile". The compression format is designed to be extended, and for new profiles to be added in the future. For this reason, enabling the WebGL extension enables all of the profiles supported by the implementation. The supported profiles may be queried by calling getSupportedProfiles against the extension object. Compression format COMPRESSED_RGBA_ASTC_4x4_KHR, COMPRESSED_RGBA_ASTC_5x4_KHR, COMPRESSED_RGBA_ASTC_5x5_KHR, COMPRESSED_RGBA_ASTC_6x5_KHR, COMPRESSED_RGBA_ASTC_6x6_KHR, COMPRESSED_RGBA_ASTC_8x5_KHR, COMPRESSED_RGBA_ASTC_8x6_KHR, COMPRESSED_RGBA_ASTC_8x8_KHR, COMPRESSED_RGBA_ASTC_10x5_KHR, COMPRESSED_RGBA_ASTC_10x6_KHR, COMPRESSED_RGBA_ASTC_10x8_KHR, COMPRESSED_RGBA_ASTC_10x10_KHR, COMPRESSED_RGBA_ASTC_12x10_KHR, COMPRESSED_RGBA_ASTC_12x12_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_4x4_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_5x4_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_5x5_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_6x5_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_6x6_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_8x5_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_8x6_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_8x8_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_10x5_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_10x6_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_10x8_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_10x10_KHR, COMPRESSED_SRGB8_ALPHA8_ASTC_12x10_KHR, and COMPRESSED_SRGB8_ALPHA8_ASTC_12x12_KHR may be passed to the compressedTexImage2D and compressedTexSubImage2D entry points. Calling getParameter with the argument COMPRESSED_TEXTURE_FORMATS will include the format from this specification.
