WEBGL_compressed_texture_astc: getSupportedProfiles() method

The WEBGL_compressed_texture_astc.getSupportedProfiles() method returns an array of strings containing the names of the ASTC profiles supported by the implementation.

Syntax

js

getSupportedProfiles()

Parameters

None.

Return value

An Array of string elements indicating which ASTC profiles are supported by the implementation. Currently, this can be:

  • "ldr": Low Dynamic Range.
  • "hdr": High Dynamic Range.

Dynamic range refers to ratio between the brightest and darkest parts of the scene. Low dynamic ranges are for example JPEG format images which won't exceed 255:1, or CRT monitors which won't exceed 100:1. An HDR image stores pixel values that span the whole tonal range of real-world scenes (100,000:1).

const ext = gl.getExtension("WEBGL_compressed_texture_astc");
ext.getSupportedProfiles(); // ["ldr"]
