323222 - Line not drawn to arc() if no preceded by drawing or moveTo()

Status: RESOLVED DUPLICATE of bug 296763

(Core :: Graphics: Canvas2D, defect)

Description

[Tim Altman]

According to the arc() definition, "The [arc] start point is added to the list of points of the subpath and the current position is joined to that point by a straight line."

Firefox 1.5 does not follow this rule unless there is drawing or an explicit moveTo() prior to the arc().  This should not be necessary, as according to the definition of beginPath() a) "When the context is created, a call to beginPath() is implied," and b) "The beginPath() method resets the list of subpaths to an empty list, and calls moveTo() with the point (0,0)."
