| PlgBlt The PlgBlt function performs a bit-block transfer of the bits of color data from the specified rectangle in the source device context to the specified parallelogram in the destination device context. If the given bitmask handle identifies a valid monochrome bitmap, the function uses this bitmap to mask the bits of color data from the source rectangle. VB4-32,5,6

· hdcDest
Identifies the destination device context.
· lpPoint
Points to an array of three points in logical space that identify three corners of the destination parallelogram. The upper-left corner of the source rectangle is mapped to the first point in this array, the upper-right corner to the second point in this array, and the lower-left corner to the third point. The lower-right corner of the source rectangle is mapped to the implicit fourth point in the parallelogram.
· hdcSrc
Identifies the source device context.
· nXSrc
Specifies the x-coordinate, in logical units, of the upper-left corner of the source rectangle.
· nYSrc
Specifies the y-coordinate, in logical units, of the upper-left corner of the source rectangle.
· nWidth
Specifies the width, in logical units, of the source rectangle.
· nHeight
Specifies the height, in logical units, of the source rectangle.
· hbmMask
Identifies an optional monochrome bitmap that is used to mask the colors of the source rectangle.
· xMask
Specifies the x-coordinate of the upper-left corner of the the monochrome bitmap.
· yMask
Specifies the y-coordinate of the upper-left corner of the the monochrome bitmap. |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError. |
