Flags Parameter For DotRemove

Flags

Flags that determine the behavior of the dot removal process. Flags may be combined using a bitwise OR. Possible values are:

Value	Meaning
DOT_SINGLE_REGION:	For each dot found by the DotRemove method, if the DocCleanSuccess property is set to SUCCESS_REMOVE in the DotRemove event, the removed dot is added to an internal single region. If the DocCleanSuccess property is set to SUCCESS_NOREMOVE, the dot is not added to the single region. When the DotRemove method returns, either
	1. LEADRasterView.Raster will contain a region that contains all removed dots. This is the case if the DOT_LEAD_REGION has also been set. This region can be destroyed using the DeleteRgnHandle method of LEADRasterView.Raster or
	2. the hDocCleanRgn property will reference a Windows region that contains all the removed dots. This is the case if the DOT_LEAD_REGION has NOT been set. When hDocCleanRgn is no longer needed, it must be destroyed.
	When the region (either LEAD or Windows) is no longer needed, it must be destroyed.
DOT_LEAD_REGION	This flag must be used in conjunction with DOT_LEAD_SINGLE_REGION. If this flag is set, the LEADRasterView.Raster will contain a region that contains all removed dots when the DotRemove method returns. This region can be destroyed using the DeleteRgnHandle method of LEADRasterView.Raster.
DOT_IMAGE_UNCHANGED	The original image is unchanged.
DOT_USE_DPI	The unit of measure for all parameters of this method is thousandths of an inch. Use the image's DPI to convert to pixels. This allows the processing of many images with different DPI. If this flag is not set, the unit of measure is pixels.
DOT_CALLBACK_REGION	The DotRemove event receives a Windows region that contains the current dot to be removed. Setting this flag lets the user create his or her own composite of removed dots by combining the regions received by the event, if the DocCleanSuccess property was set to SUCCESS_REMOVE in the event. The regions can be combined using a logical OR operator. Combining all regions received by the event, that are removed, results in a region identical to the region created when DOT_SINGLE_REGION is set in uFlags.
DOT_USE_SIZE	Use the iMinDotWidth, iMinDotHeight, iMaxDotWidth, iMaxDotHeight parameters to indicate the size of the dots to remove. If this flag is not set, default values for the four sizes will be used. These defaults are as follows: iMinDotWidth = 1, iMinDotHeight = 1, iMaxDotWidth = 2 and iMaxDotHeight = 2.
DOT_USE_DIAGONALS	Considers pixels that are diagonal as part of the dot. Consider the "speck" below consisting of nine pixels.

	If DOT_USE_DIAGONALS is used, this speck is considered a single dot that is 5x5 pixels. If DOT_USE_DIAGONALS is not used, the speck is considered three dots (2x2, 1x1, 2x2).
