Description

Applies a sequence of filters to the source raster in the order in which they were added. When Continue On Failure is set to true, subsequent filters will still be applied to the source raster even if one or more filters in the sequence cannot be applied.

Public Methods

Add	Adds a filter to the sequence.
Clear	Clears all filters from the sequence.
Contains	Returns true if the sequence contains the filter.
Remove	Removes a filter from the sequence.

Public Properties

ContinueOnFailure	Gets or sets whether to continue applying filters in the sequence regardless of individual filter failures. When set to true, subsequent filters will still be applied to the source raster even if one or more filters in the sequence cannot be applied.
Count	Gets the number of filters in the collection.

Example

Adjust brightness, contrast, and gamma
