DOCUMENT:Q111606 06-NOV-1999 [win16sdk] TITLE :BUG: ROP2 Code Applied Incorrectly in Pie() Function PRODUCT :Microsoft Windows Software Development Kit PROD/VER:WINDOWS:3.1 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows Software Development Kit (SDK) 3.1 ------------------------------------------------------------------------------- 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.
