Tiled Storage

The XIL 1.3 library stores very large images in buffers of memory called tiles. If a region of an image within a tile boundary is needed, only that tile is loaded into memory, thereby increasing performance.

The library also includes a new storage object, which supports conventional contiguous storage as well as tiled or stripped storage for XIL images. The storage object serves as a container for the image's attributes, such as its scanline and pixel stride, and its data pointer. Storage is not allocated for the image until you export the image and modify it directly. This saves on memory use.
