BUG: ROP2 Code Applied Incorrectly in Pie() Function (111606)
The information in this article applies to:
- Microsoft Windows Software Development Kit (SDK) 3.1
This article was previously published under Q111606 SYMPTOMS
When calling the Windows SDK function Pie() using a ROP2 code other than
the default R2_COPYPEN, and using a pen with a width greater than 1 (one),
you may notice that the pie border is not drawn correctly.
CAUSE
The pen position is applied incorrectly and overlaps part of the interior.
STATUS
Microsoft has confirmed this to be a bug in Windows version 3.1. We are
researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
MORE INFORMATION
For a demonstration of this bug, run the sample program SHOWGDI that comes
with the Windows 3.1 SDK or with Microsoft Visual C++. Set the pen width to
greater than 1 and make sure that the pen color and brush color are
different. For example, set the pen width to 5 and the pen color to
RGB(0,255,0). Set the brush color to RGB(255,0,255). Set the ROP2 code to
R2_XORPEN and then draw a pie. You will see three color ranges. The pen
position is applied incorrectly and overlaps part of the interior.
