[Bug 17982] New: PatBlt cannot draw arbitrary parallelograms based on the world transform
http://bugs.winehq.org/show_bug.cgi?id=17982 Summary: PatBlt cannot draw arbitrary parallelograms based on the world transform Product: Wine Version: 1.1.18 Platform: Other OS/Version: other Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: winex11.drv AssignedTo: wine-bugs(a)winehq.org ReportedBy: madewokherd(a)gmail.com Using the functions SetGraphicsMode and (Set|Modify)WorldTransform, it is possible to define an arbitrary matrix to transform all points as things are drawn to device contexts. Using this matrix, it should be possible to apply arbitrary rotation/shear effects. Thus, rectangles drawn on the hdc can be transformed into arbitrary parallelograms. This only works on systems where GM_ADVANCED is supported (NT but not 9x, according to MSDN). I have written a test program that demonstrates this on Windows. On Wine, it can only draw rectangles. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

http://bugs.winehq.org/show_bug.cgi?id=17982 --- Comment #3 from Vincent Povirk <madewokherd(a)gmail.com> 2009-04-13 11:25:38 --- I've tested using a hatch and pattern brush on Windows. The brush pattern is not transformed. So apparently PatBlt is equivalent to calling Polygon with the four corners of the rectangle. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

This fixes the behavior of PatBlt(), however it might have performance consequences, depending on whether Polygon() is optimized when drawing normal rectangles. If anyone is interested, I can improve it to call Polygon() only when needed - it will check if the rectangle is actually going to be inclined and call Polygon() only then. I already tested that this approach works for PatBlt(), but only when using PAT_COPY. I have not yet tested with the other ROPs. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
