[−][src]Struct ugli_webgl::WEBGL_compressed_texture_s3tc_srgb

pub struct WEBGL_compressed_texture_s3tc_srgb(_);

Extension

This extension exposes the sRGB compressed texture formats defined in the EXT_texture_sRGB OpenGL extension to WebGL. Compression formats COMPRESSED_SRGB_S3TC_DXT1_EXT, COMPRESSED_SRGB_ALPHA_S3TC_DXT1_EXT, COMPRESSED_SRGB_ALPHA_S3TC_DXT3_EXT, and COMPRESSED_SRGB_ALPHA_S3TC_DXT5_EXT may be passed to the compressedTexImage2D and compressedTexSubImage2D entry points. Calling getParameter with the argument COMPRESSED_TEXTURE_FORMATS will include the 4 formats from this specification.

The following format specific restrictions must be enforced: COMPRESSED_SRGB_S3TC_DXT1_EXT COMPRESSED_SRGB_ALPHA_S3TC_DXT1_EXT

The byteLength of the ArrayBufferView, pixels, passed to either compressedTexImage2D or compressedTexSubImage2D must match the following equation:

floor((width + 3) / 4) * floor((height + 3) / 4) * 8

If it is not an INVALID_VALUE error is generated.

When level equals zero width and height must be a multiple of 4. When level is greater than 0 width and height must be 0, 1, 2 or a multiple of 4.

If they are not an INVALID_OPERATION error is generated.

For compressedTexSubImage2D xoffset and yoffset must be a multiple of 4 and width must be a multiple of 4 or equal to the original width of the level. height must be a multiple of 4 or equal to the original height of the level. If they are not an INVALID_OPERATION error is generated. COMPRESSED_SRGB_ALPHA_S3TC_DXT3_EXT COMPRESSED_SRGB_ALPHA_S3TC_DXT5_EXT

The byteLength of the ArrayBufferView, pixels, passed to either compressedTexImage2D or compressedTexSubImage2D must match the following equation:

floor((width + 3) / 4) * floor((height + 3) / 4) * 16

If it is not an INVALID_VALUE error is generated.

When level equals zero width and height must be a multiple of 4. When level is greater than 0 width and height must be 0, 1, 2 or a multiple of 4.

If they are not an INVALID_OPERATION error is generated.

For compressedTexSubImage2D xoffset and yoffset must be a multiple of 4 and width must be a multiple of 4 or equal to the original width of the level. height must be a multiple of 4 or equal to the original height of the level. If they are not an INVALID_OPERATION error is generated.
