GPU-accelerated rendering » Texture objects

Prev:	texture-dim ( tdt level -- dim )
Next:	read-texture-to ( tdt: texture-data-target level: integer gpu-data-ptr -- )

Vocabulary

Inputs

tdt	a texture-data-target
level	an integer

Outputs

byte-array

a byte-array

Word description
Reads the entire image for the levelth level of detail of a texture into a new byte-array. The format of the data in the byte array is determined by the component-order and component-type of the texture.
