Pixbuf.scale

void scale(gdkpixbuf.pixbuf.Pixbuf dest,  int  destX,  int  destY,  int  destWidth,  int  destHeight,  double  offsetX,  double  offsetY,  double  scaleX,  double  scaleY,  gdkpixbuf.types.InterpType interpType)

Creates a transformation of the source image src by scaling by scale_x and scale_y then translating by offset_x and offset_y, then renders the rectangle (dest_x, dest_y, dest_width, dest_height) of the resulting image onto the destination image replacing the previous contents.

Try to use [gdkpixbuf.pixbuf.Pixbuf.scaleSimple] first; this function is the industrial-strength power tool you can fall back to, if [gdkpixbuf.pixbuf.Pixbuf.scaleSimple] isn't powerful enough.

If the source rectangle overlaps the destination rectangle on the same pixbuf, it will be overwritten during the scaling which results in rendering artifacts.

Parameters

`dest`	the #GdkPixbuf into which to render the results
`destX`	the left coordinate for region to render
`destY`	the top coordinate for region to render
`destWidth`	the width of the region to render
`destHeight`	the height of the region to render
`offsetX`	the offset in the X direction (currently rounded to an integer)
`offsetY`	the offset in the Y direction (currently rounded to an integer)
`scaleX`	the scale factor in the X direction
`scaleY`	the scale factor in the Y direction
`interpType`	the interpolation type for the transformation.
