Parameters

format

Type: SystemInt32
the compressed format of the texel data.

xOffset

Type: SystemInt32
texel offset in the X direction within the texture array.

yOffset

Type: SystemInt32
texel offset in the Y direction within the texture array.

width

Type: SystemInt32
the width of the texture subimage.

height

Type: SystemInt32
the height of the texture subimage.

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 redefines a contiguous subregion of an existing two-dimensional texture image. The texels referenced by data replace the portion of the existing texture array with X indices xOffset and xOffset + width - 1, and the Y indices yOffset and yOffset + height - 1, inclusive. This region may not include any texels outside the range of the texture array as it was originally specified. It is not an error to specify a subtexture with width of 0, but such a specification has no effect.

format must be the same extension-specified compressed-texture format previously specified by UploadCompressedT(Int32, Int32, Int32, T, Int32, Int32).

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.
