gdkPixbufComposite: gdkPixbufComposite

In RGtk2: R Bindings for Gtk 2.8.0 and Above

Description

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 composited onto the corresponding rectangle of the original destination image.

Usage

gdkPixbufComposite(object, dest, dest.x, dest.y, dest.width, 
    dest.height, offset.x, offset.y, scale.x, scale.y, interp.type, 
    overall.alpha)

Arguments

object	a GdkPixbuf
dest	the GdkPixbuf 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)

Details

When the destination rectangle contains parts not in the source image, the data at the edges of the source image is replicated to infinity.
