TiledMemory # get and set (CodecsLoadOptions)
Value | Description |
---|---|
true | To enable loading the image as tiled, useful for very large images. |
false | To disable loading the image as tiled. The default value is false. |
When the value of this property is true, the image is created where the data pointers are maintained in tiles, useful for very large images.
