Dim flags As CombineCommandFlags
 
Dim instance As New CombineCommand(sourceImage, destinationRectangle, sourcePoint, flags)

public CombineCommand(

   LeadRect destinationRectangle, 
   LeadPoint sourcePoint, 
   int flags
)

function CombineCommand( 
   sourceImage ,
   destinationRectangle ,
   sourcePoint ,
   flags 
)

public:
CombineCommand( 
   RasterImage^ sourceImage,
   LeadRect destinationRectangle,
   LeadPoint sourcePoint,
   CombineCommandFlags flags
)

Parameters

sourceImage

RasterImage object that references the source image, which is combined with the destination image.

destinationRectangle

LeadRect structure that contains the destination rectangle.

sourcePoint

LeadPoint structure that contains the origin of the source rectangle. The width and height of the source rectangle are the same as the destination rectangle.

flags

Flags from seven groups that define treatment of the source, treatment of the destination, the operation to use when combining the data, treatment of the resulting image, and the color plane for the destination, source and resulting images. The flags apply only to the defined rectangles (not necessarily the whole image). You can use a bitwise OR ( | ) to specify one flag from each group.

In order to speed up widely used image processing filters in LEADTOOLS, the grayscale value (master channel) of a colored image is calculated using the following formulas:

             #define CalcGrayValue(r, g, b) ((L_UCHAR)(((L_UCHAR) (((2 * (L_UINT) (r)) + (5 * (L_UINT) (g)) + (L_UINT) (b) + 4) / 8))))
             #define CalcGrayValue16(r, g, b) ((L_UINT16) (((2 * (L_UINT32) (r)) + (5 * (L_UINT32) (g)) + (L_UINT32) (b) + 4) / 8))
             #define CalcGrayValue32(r, g, b) ((L_UINT32) (((2 * (L_UINT32) (r)) + (5 * (L_UINT32) (g)) + (L_UINT32) (b) + 4) / 8))

Run the CombineCommand on an image.
