compressedTexSubImage2D method

void compressedTexSubImage2D(
  1. GLenum target,
  2. GLint level,
  3. GLint xoffset,
  4. GLint yoffset,
  5. GLsizei width,
  6. GLsizei height,
  7. GLenum format,
  8. ArrayBufferView data,
)

The WebGLRenderingContext.compressedTexSubImage2D() method of the WebGL API specifies a two-dimensional sub-rectangle for a texture image in a compressed format.

Compressed image formats must be enabled by WebGL extensions before using this method or a WebGL2RenderingContext must be used.

Implementation

external void compressedTexSubImage2D(
  GLenum target,
  GLint level,
  GLint xoffset,
  GLint yoffset,
  GLsizei width,
  GLsizei height,
  GLenum format,
  ArrayBufferView data,
);
