Creates a transformation of the source image src by scaling by scale_x and scale_y then translating by offset_x and offset_y. This gives an image in the coordinates of the destination pixbuf. The rectangle (dest_x, dest_y, dest_width, dest_height) is then alpha blended onto the corresponding rectangle of the original destination image.
When the destination rectangle contains parts not in the source image, the data at the edges of the source image is replicated to infinity.
the gdk.Pixbuf into which to render the results
the left coordinate for region to render
the top coordinate for region to render
the width of the region to render
the height of the region to render
the offset in the X direction (currently rounded to an integer)
the offset in the Y direction (currently rounded to an integer)
the scale factor in the X direction
the scale factor in the Y direction
the interpolation type for the transformation.
