A gdiplus bug-outofmemory exception

 

Today we found a gdiplus bug in framework2.0:

Write the following code in the form onpaint event:

Private void form1_paint (Object sender, painteventargs E)
{
Pen P = new pen (color. Red );
P. width = 1;
P. dashstyle = dashstyle. Dot;
P. dashoffset = 1;
E. Graphics. drawline (p, new point (58, 8), new point (58, 9 ));
P. Dispose ();
}

The system will throw an outofmemory exception from native's GDI plus code.

To sum up, the conditions are as follows:

1. The line type is dot.

2. The line width is 1.

3. dashoffset is 1

4. Draw only one pixel

Ms processing results, they confirm this is a bug, but are not prepared to fix
