public void getData(java.nio.ByteBuffer out)

Description copied from interface: TextureContent

Get raw byte data of content, rasterized in row-major form, with (0,0) in the bottom-left corner.

Specified by:

getData in interface TextureContent

getData

public void getData(Rectangle rect,
                    java.nio.ByteBuffer out)

Description copied from interface: TextureContent

Get raw byte data for a region, rasterized in row-major form with (0,0) in the bottom-left corner.

Specified by:

getData in interface TextureContent

Parameters:
