301046 - stroke overly significant when graphics are scaled down

Status: RESOLVED INVALID

(Core :: SVG, defect)

Description

[Jonathan Watt [:jwatt]]

I've adapted one of the W3C testcases to show this. When you view it, try
resizing the window to make the image very small and you'll see the red stroke
is far to prominent. Maybe this is a problem for the GDI+ backend only?

Jonathan, I'm not seeing this on Linux/Cairo.  Looks like it might be a GDI+
thing, as you suspected.

I'm not seeing anything odd either.  The stroke remains the same size all the
way down. Eventually the fill is to small to render so only the stroke is
visible at that point.

Yeah, that's my point. The stroke should become so "thin" it disappears before
the fill does. According to tor GDI+ doesn't allow strokes to be less than 1px
wide. If you attempt to draw use a stroke of less than 1px, it just gets rounded
up. I've just tested using cairo as the backend on windows and it works fine
like Scooter says. Since it's a GDI+ issue and out of our hands, marking this
invalid. Yet another reason for us to move to cairo on w32.
