OutOfBoundsStrategy

Purpose

The enum type OutOfBoundsStrategy defines the following options for handling pixel coordinates that are outside the image:

• DefaultValue: Replace out-of-bounds pixels by some default value.
• NearestBorder: Replace out-of-bounds pixels with the nearest border pixel.
• MirrorImage: Treat the image as being infinitely mirrored at its borders.
• PeriodicImage: Treat the image as repeating ininitely in x/y directions.
• ThrowException: Throw an exception when out-of-boundary coordinates are accessed.

Examples

The following examples show how the original image (marked by the green rectangle) is extended by the different out-of-bounds strategies. The resulting effective images extend to infinity in all directions.
