scaleSimple
Create a new pixbuf containing a copy of src
scaled to dest_width
x dest_height
.
This function leaves src
unaffected.
The interp_type
should be GDK_INTERP_NEAREST
if you want maximum speed (but when scaling down GDK_INTERP_NEAREST
is usually unusably ugly). The default interp_type
should be GDK_INTERP_BILINEAR
which offers reasonable quality and speed.
You can scale a sub-portion of src
by creating a sub-pixbuf pointing into src
; see method@GdkPixbuf.Pixbuf.new_subpixbuf.
If dest_width
and dest_height
are equal to the width and height of src
, this function will return an unscaled copy of src
.
For more complicated scaling/alpha blending see method@GdkPixbuf.Pixbuf.scale and method@GdkPixbuf.Pixbuf.composite.
Return
the new pixbuf
Parameters
the width of destination image
the height of destination image
the interpolation type for the transformation.
