WEBGL_compressed_texture_astc: getSupportedProfiles() method
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).
Examples

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