Graphics Ports supports drawing images, and also reading/writing them from/to file via your code. A wide range of image types is supported. Also, several CAPI classes support the same image types.
To draw an image with Graphics Ports, you need an
image
object which is associated with an instance of
capi:output-pane
(or a subclass of this). You can create a
image
object from:
external-image
object
Draw the image to the pane by calling
draw-image
. Certain images ("Plain Images") can be manipulated via the Image Access API. The image should be freed by calling
free-image
when you are done with it.
capi:image-pinboard-object
,
capi:button
,
capi:list-view
,
capi:tree-view
and
capi:toolbar
all support images. There is also limited support for images in
capi:menu
. These classes handle the drawing and freeing for you.
