Re: bug - graphicsContext>>displayRectangularBorder:

It works fine for me (Windows 8, 7.4.1, 7.7.1 and 7.9.feb12.1). Which VW version and platform do you see the problem on, and is it a virgin visual.im?

For me it falls back to #displayGeneralPolyline:, and closed=true.

#displayWideLineSetup:from:to: returns true, proj and round are false,

when entering displayWideLineJoinFrom:, points is:

#(3 @ 3 19 @ 3 19 @ 19 3 @ 19 3 @ 3)

and in the 4 calls to primDisplayPolygon:to: at the end of that method, bpoly is respectively:

#(3 @ 4 2 @ 3 2 @ 2 19 @ 2 19 @ 4)

#(18 @ 3 19 @ 2 20 @ 2 20 @ 19 18 @ 19)

#(19 @ 18 20 @ 19 20 @ 20 3 @ 20 3 @ 18)

#(4 @ 19 3 @ 20 2 @ 20 2 @ 3 4 @ 3)

All the best,
Steve

Terry,

Perform the following code and closely examine the upper left corner
of the rectangle. Notice that the rectangle is not closed.
