Provides access to members that control pixel block level editing operations.
Description
IRasterEdit allows you to modify the pixel values in a Raster usingPixelBlocks. Refresh after you call Write to flush the changes.
When editing raster in Enterprise geodatabase or File geodatabase, the NoData is mask based, not pixel value based, if you want to edit NoData pixels (either set a value pixel to a NoData pixel or a NoData pixel to be a value pixel), IPixelBlock3.NoDataMask should be used to flag the NoData pixels.
