#include <murl_resource_i_image.h>
An IFF chunk containing the actual image data for a specific MIP level.
A native image must at least contain one MIP level chunk within each of its stream chunks representing the (unscaled) base level.

Public Attributes | |
UInt32 | mMipLevel |
The actual MIP level (0 equals the base level). | |
UInt32 | mPixelSizeX |
The horizontal size of the image at the given MIP level in pixels. | |
UInt32 | mPixelSizeY |
The vertical size of the image at the given MIP level in pixels. | |
UInt32 | mBytesPerLine |
The line pitch in bytes. | |
UInt32 | mDataOffset |
An offset into the chunk where the image data is stored. See IffOffset(). | |
UInt32 | mDataByteSize |
The total size in bytes of the contained image data. | |
