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
