Web/API/WEBGL compressed texture astc/getSupportedProfiles

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

Syntax

sequence<DOMString> ext.getSupportedProfiles();

Return value

An Array of DOMString 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

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