Copies an area bounded by x1, y2, x2, y2 in the source context to the current context at the location specified by dx, dy using the specified operation.
This function does not perform clipping. If you cannot ensure that the destination rectangle is within the bounds of the context, then use bit_blt instead.
x |
the destination X coordinate |
y |
the destination Y coordinate |
src |
the source context or null to use the current context |
x1 |
the source bounding rectangle left coordinate |
y1 |
the source bounding rectangle top coordinate |
x2 |
the source bounding rectangle right coordinate |
y2 |
the source bounding rectangle bottom coordinate |
op |
the ColorMode operator and optional transparent color |
