A real number in the inclusive range [0,1], or

The
draw-image
function displays
image
on the port at
to-x
to-y
. Graphics state translation is guaranteed to be supported. The default value of
from-x
and
from-y
is 0. The
width
and
height
arguments default to the size of the image.
Support for scaling and rotation are library dependent. Specifically, scaling is supported in the Windows and Cocoa implementations, but not on X11/Motif.
global-alpha
, if non-
nil
, is a blending factor that applies to the whole image, in the Windows and Cocoa implementations, but not on X11/Motif. The value 0 means use only the target (that is, do not draw anything) and the value 1 means use only the source (that is, normal drawing). Intermediate real values mean use proportions of both the target and source. The value
nil
also means normal drawing, and this is the default value.
