Parameters

format

Type: SystemInt32
the compressed format of the texel data.

width

Type: SystemInt32
the width of the texture image. All implementations support 2D texture images that are at least 64 texels wide and cube-mapped texture images that are at least 16 texels wide.

height

Type: SystemInt32
the height of the texture image. All implementations support 2D texture images that are at least 64 texels high and cube-mapped texture images that are at least 16 texels high.

data

Type: T
array containing the compressed image data in memory.

level (Optional)

Type: SystemInt32
(optional) level-of-detail number if updating separate mipmap levels. Level 0 (default) is the base image level. Level N is the Nth mipmap reduction image.

cubeTarget (Optional)

Type: SystemInt32
(optional) if this texture is a cube texture, then this parameter specifies which of the 6 cube faces to update. This parameter is ignored for 2D textures.

Type Parameters

T

the type of data in the data array

Texturing maps a portion of a specified texture image onto each graphical primitive for which texturing is active. Texturing is active when the current fragment shader or vertex shader makes use of built-in texture lookup functions.

This method defines a two-dimensional texture image or cube-map texture image using compressed image data from client memory. The texture image is decoded according to the extension specification defining the specified format. OpenGL ES defines no specific compressed texture formats, but does provide a mechanism to obtain symbolic constants for such formats provided by extensions. The list of specific compressed texture formats supported can be obtained by CompressedTextureFormats.

Note: a GL implementation may choose to store the texture array at any internal resolution it chooses.

Note: this method specifies a two-dimensional or cube-map texture for the current texture unit, specified with BindToTextureUnit(Int32).

Note: in DEBUG mode with assertions enabled, an error will be logged to the debug console if this texture is not bound.

Note: Undefined results, including abnormal program termination, are generated if data is not encoded in a manner consistent with the extension specification defining the internal compression format.
