Description [src]

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 gdk_pixbuf_scale_simple() first; this function is the industrial-strength power tool you can fall back to, if gdk_pixbuf_scale_simple() 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.


dest GdkPixbuf

The GdkPixbuf into which to render the results.

 The data is owned by the caller of the function.
dest_x int

The left coordinate for region to render.

dest_y int

The top coordinate for region to render.

dest_width int

The width of the region to render.

dest_height int

The height of the region to render.

offset_x double

The offset in the X direction (currently rounded to an integer)

offset_y double

The offset in the Y direction (currently rounded to an integer)

scale_x double

The scale factor in the X direction.

scale_y double

The scale factor in the Y direction.

interp_type GdkInterpType

The interpolation type for the transformation.
