4.6 Graphics Context

All Graphics Context objects have methods that perform drawing operations. They are listed here, with the argument types they expect. XPoint is a pair of integers; XRectangle is a tuple of four integers; XSegment is a tuple of four integers; XArc is a tuple of six integers; <type>[] stands for a list of <type> objects.

All GC objects have data attributes representing the individual values. These are gc.line_width, gc.line_style, etc. (The dash attribute is not supported.) These attributes can be assigned to if the GC object is writable.

The Pixmap arguments are Pixmap objects; the Font arguments are Font objects; the Image arguments are Image objects.
