DistCy
[in] Specifies the height, in logical units, of the destination rectangle.
hSrc
[in] Specifies a source device context or a source bitmap.
SrcX

SrcY
[in] Specifies the y-coordinate, in logical units, of the upper-left corner of the source rectangle.
SrcCx
[in] Specifies the width, in logical units, of the source rectangle.
SrcCy
[in] Specifies the height, in logical units, of the source rectangle.
