Description:
powerful object-oriented display engine - documentation files
The canvas widget is a powerful and extensible object-oriented display engine. A GnomeCanvasItem is a GtkObject representing some element of the display, such as an image, a rectangle, an ellipse, or some text. You can refer to this architecture as structured graphics; the canvas lets you deal with graphics in terms of items, rather than an undifferentiated grid of pixels. . This package contains documentation files.
