gdk-pixbuf:pixbuf-composite-color (src dest x y width height xoffset yoffset xscale  yscale interp alpha xcheck ycheck size color1 color2)

src -- a gdk-pixbuf:pixbuf object
dest -- a gdk-pixbuf:pixbuf object into which to render the results
x -- an integer with the left coordinate for region to render
y -- an integer with the top coordinate for region to render
width -- an integer with the width of the region to render
height -- an integer with the height of the region to render
xoffset -- a number coerced to a double float with the offset in the x direction, currently rounded to an integer
yoffset -- a number coerced to a double float with the offset in the y direction, currently rounded to an integer
xscale -- a number coerced to a double float with the scale factor in the x direction
yscale -- a number coerced to a double float with the scale factor in the y direction
interp -- a gdk-pixbuf:pixbuf-interp-type interpolation type for the transformation
alpha -- an integer with the overall alpha for source image (0..255)
xcheck -- an integer with the x offset for the checkboard, origin of checkboard is at (-xcheck, -ycheck)
ycheck -- an integer with the y offset for the checkboard
size -- an integer with the size of checks in the checkboard, must be a power of two
color1 -- an unsigned integer with the color of check at upper left
color2 -- an unsigned integer with the color of the other check

Creates a transformation of the source image src by scaling by xscale and yscale then translating by xoffset and yoffset, then composites the rectangle (x,y,width,height) of the resulting image with a checkboard of the colors color1 and color2 and renders it onto the destination image.

See the gdk-pixbuf:pixbuf-composite-color-simple function for a simpler variant of this function suitable for many tasks.
