Struct ugli_webgl::EXT_texture_compression_bptc

pub struct EXT_texture_compression_bptc(_);

Extension

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

Sampling from textures in the COMPRESSED_SRGB_ALPHA_BPTC_UNORM_EXT format performs a color space conversion as specified for SRGB textures in the EXT_sRGB OpenGL ES extension. Compression format COMPRESSED_RGBA_BPTC_UNORM_EXT, COMPRESSED_SRGB_ALPHA_BPTC_UNORM_EXT, COMPRESSED_RGB_BPTC_SIGNED_FLOAT_EXT, and COMPRESSED_RGB_BPTC_UNSIGNED_FLOAT_EXT may be passed to the compressedTexImage2D and compressedTexSubImage2D entry points. Calling getParameter with the argument COMPRESSED_TEXTURE_FORMATS will include the formats from this specification.

If the internalformat is one of the BPTC internal formats from this specification, the byteLength of the ArrayBufferView, pixels, passed to compressedTexImage2D or compressedTexSubImage2D must be equal to the following number of bytes:

ceil(width / 4) * ceil(height / 4) * 16

If it is not, an INVALID_VALUE error is generated.

impl Extension for EXT_texture_compression_bptc

const NAME: &'static str

impl From<EXT_texture_compression_bptc> for Reference

fn from(value: EXT_texture_compression_bptc) -> Self

Performs the conversion.

impl InstanceOf for EXT_texture_compression_bptc

fn instance_of(_reference: &Reference) -> bool

Checks whenever a given Reference if of type Self.
