Summary: mono's GraphicsPathTest.AddString_NegativeSize test
fails
Product: Wine
Version: 1.5.4
Platform: x86
OS/Version: Linux
Status: NEW
Keywords: download, regression, source, testcase
Severity: normal
Priority: P2
Component: gdiplus

This is a new failure that came up today when I ran the Mono System.Drawing
tests:
28) MonoTests.System.Drawing.Drawing2D.GraphicsPathTest.AddString_NegativeSize
: System.ArgumentException : A null reference or invalid value was found [GDI+
status: InvalidParameter]

Here's the code for that test:
public void AddString_NegativeSize ()
{
GraphicsPath gp = new GraphicsPath ();
FontFamily ff = GetFontFamily ();
gp.AddString ("mono", ff, 0, -10, new Point (10, 10),
StringFormat.GenericDefault);
Assert.IsTrue (gp.PointCount > 0, "PointCount");
}
Bisecting gave me this:

gdiplus: Retrieve LOGFONT from a GpFont using GdipGetLogFontW instead of
accessing it directly.
It seems it's valid to call GdipAddPathString with a negative font size. This
fails now because GdipCreateFont doesn't accept a negative font size, but I
don't know if it's correct for GdipAddPathString to call GdipCreateFont.
I can provide a compiled version of the System.Drawing tests if that would
help.
