Method Blit
Blit(PointD, SizeD, Graphics, PointD, RasterOperationMode, bool, PointD?, GraphicsUnit)
Copy from a source Graphics to this graphics. With this method you can specify the destination coordinates and the size of area to copy which will be the same for both the source and target. If you need to apply scaling while copying, use StretchBlit(PointD, SizeD, Graphics, PointD, SizeD, RasterOperationMode, bool, PointD?, GraphicsUnit). Sizes and positions are specified in pixels.
bool Blit(PointD destPt, SizeD sz, Graphics source, PointD srcPt, RasterOperationMode rop = RasterOperationMode.Copy, bool useMask = false, PointD? srcPtMask = null, GraphicsUnit unit = GraphicsUnit.Dip)
Parameters
destPtPointDDestination device context position.
szSizeDSize of source area to be copied.
sourceGraphicsSource device context.
srcPtPointDSource device context position.
ropRasterOperationModeLogical function to use.
useMaskboolIf true, Blit does a transparent blit using the mask that is associated with the bitmap selected into the source device context.
srcPtMaskPointD?Source position on the mask. If it equals (-1, -1),
srcPtwill be assumed for the mask source position. Currently only implemented on Windows.unitGraphicsUnitGraphicsUnit that determines the unit of measure for the point and size parameters.
Returns
Remarks
Notice that source coordinate srcPt is interpreted
using the current source DC coordinate system, i.e. the scale, origin position
and axis directions are taken into account when transforming them to
physical(pixel) coordinates.
