Summary: MFC fillrect draws differently under wine Product: Wine Version: 1.3.21 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: gdi32 AssignedTo: wine-bugs@winehq.org ReportedBy: bailey937@yahoo.com
Created an attachment (id=35259) --> (http://bugs.winehq.org/attachment.cgi?id=35259) sample program for reproducing FillRect bug
I have a program that uses CPaintDC.FillRect() to draw histogram samples.
It draws one-pixel wide vertical rectangles.
Under wine, the bottom-most pixel is not drawn.
I'm attaching a sample program. Under Windows7 (have 64bit pro), the red line is touching the black baseline and the black line on the right is touching the baseline also.
When I run the program under wine, both the red vertical line on the left and the black vertical line on the right are floating one pixel above the baseline.
I tried both 32bit Ubuntu 11.04 (wine 1.2.2) on a netbook and also Fedora 15 64bit (wine 1.3.21) under Virtualbox on my Windows machine. Both have the same problem.
The relevant code for the test case is in
CChildView::OnPaint() in ChildView.cpp

We generally like C examples without MFC, so I converted your example, see attachment.

--- Comment #3 from bailey937@yahoo.com 2011-06-25 06:38:22 CDT --- Thank you for translating it.
With the MS compiler, you need to move the declaration "int i = 0;" in onPaintBroken() up (it doesn't like variables being declared in the middle of a function in a .c file).
I built your translated example, and it reproduces the bug just like my original sample.
Thanks again.

--- Comment #8 from Thomas Faller tfaller1@gmx.de --- There is no pixel missing. The position of the baseline is wrong because bottom and top are swapped:
From the exampel source:
... void onPaintBroken(HDC hdc) ... r.bottom = 115+110; r.top = 115+110 + 1; ...
Windows does not care about this, wine does. All is correct if I swap bottom and top.

--- Comment #10 from Nikolay Sivov bunglehead@gmail.com --- It's not fixed in 1.9.16.

--- Comment #12 from Damjan Jovanovic damjan.jov@gmail.com --- There is a real bug here. FillRect() calls PatBlt(), passing it a negative width/height in the case of this app, and PatBlt() draws rectangles with negative width/height shifted 1 pixel too far right/down:
Windows (0,0) +------+ |+-----++ || || || || ++-----+| +------+ Wine
Patch with test sent: https://source.winehq.org/patches/data/195952
The testcase draws correctly with this patch.
