The method copies the color data for a rectangle of pixels from a page to the specified destination rectangle. If the destination rectangle is larger than the source rectangle, this function stretches the rows and columns of color data to fit the destination rectangle. If the destination rectangle is smaller than the source rectangle, this function compresses the rows and columns by using the specified raster operation.

The method copies the color data for a rectangle of pixels from a page to the specified destination rectangle. If the destination rectangle is larger than the source rectangle, this function stretches the rows and columns of color data to fit the destination rectangle. If the destination rectangle is smaller than the source rectangle, this function compresses the rows and columns by using the specified raster operation.

nSrcTop
[in] specifies the y-coordinate of the left-top corner of the affected rectangle in the source page.
nSrcRight
[in] specifies the x-coordinate of the right-bottom corner of the affected rectangle in the source page.
nSrcBottom
[in] specifies the y-coordinate of the right-bottom corner of the affected rectangle in the source page.
nScaleMethod
[in] Value of IXC_ScaleMethod specifies the method which will be used for scaling the image.
