Method Detail

doBlit

void doBlit(sun.java2d.SurfaceData src,
          sun.java2d.SurfaceData dst,
          Composite comp,
          int sx,
          int sy,
          int dx,
          int dy,
          int w,
          int h)

Performs the actual blit operation. This method gets called 0 - N times, depending on the clip:

• If the clip or the clipped source and/or destination area is empty, then it is not called at all
• If the clip is rectangular, then it is called once, with source and destination clipped accordingly.
• If the clip is non-rectangular, it is called 1 - N times, depending on the complexity of the clip. The source and destination areas span parts of the original source and destination area, clipped against tiles of the clip.

Parameters:

src - the source surface

dst - the destination surface

comp - the composite setting

sx - the source area, upper left X coordinate

sy - the source area, upper left Y coordinate

dx - the destination area, upper left X coordinate

dy - the destination area, upper left Y coordinate

w - the width of the source/destination area

h - the height of the source/destination area
