composite

Description:

public void composite (Pixbuf dest, int dest_x, int dest_y, int dest_width, int dest_height, double offset_x, double offset_y, double scale_x, double scale_y, InterpType interp_type, int overall_alpha)

Creates a transformation of the source image this 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.

Parameters:

this	a Pixbuf
dest	the Pixbuf into which to render the results
dest_x	the left coordinate for region to render
dest_y	the top coordinate for region to render
dest_width	the width of the region to render
dest_height	the height of the region to render
offset_x	the offset in the X direction (currently rounded to an integer)
offset_y	the offset in the Y direction (currently rounded to an integer)
scale_x	the scale factor in the X direction
scale_y	the scale factor in the Y direction
interp_type	the interpolation type for the transformation.
overall_alpha	overall alpha for source image (0..255)
