User [EMAIL PROTECTED] added comment https://bugzilla.novell.com/show_bug.cgi?id=410124#c409672 Summary: FillPath renders "bloated" after scaling the graphics transform. Product: Mono: Class Libraries Version: 1.9.0 Platform: Other OS/Version: Linux Status: NEW Severity: Normal Priority: P5 - None Component: Sys.Drawing. AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] QAContact: [email protected] Found By: Other Created an attachment (id=228570) --> (https://bugzilla.novell.com/attachment.cgi?id=228570) Windows Zip Description of Problem: ----------------------- When assigning a scaling transform to a Graphics object, Graphics.FillPath() method renders fine under Windows and Win32 Mono, but "bloated" (NOT translated)under Mono for Linux. Although similar steps were described by BUG #409672, I question if the results here can be explained by the Cairo pixel offset identified in the response to that bug report. Steps to reproduce the problem: ------------------------------- I have included (zipped) a solution created with Microsoft Visual C# Express Edition. The source files and a release executable are provided. A post-build step will copy the exe to 'bug1.exe' for ease-of-use on linux. 1. run the included 'bug1.exe' on linux (mono bug1.exe) 2. cringe at the results Actual Results: --------------- The included sample application creates a rectangle (rTest) 5 units in width and height. A scaling factor is then calculated to map rTest to the Form's client rectangle. This scaling factor is applied to the graphics object with Matrix X = new Matrix(fSceneScaler, 0, 0, fSceneScaler, 0, 0); g.Transform = X; when DrawPath(...) is called, it works as expected, but when FillPath(...) is called, it will render bloated (bigger) by some amount. By changing the rTest size to something smaller, the effect is more dramatic. By changing the rTest size to something larger (say 300 units), the effect becomes negligable. Expected Results: ----------------- The Linux output should match the Windows output, right? How often does this happen? --------------------------- Every Time. Additional Information: ----------------------- - These sample sources were compiled on Windows XP SP2. - The Linux results were seen on Fedora Core 3 running Mono 1.9.1 installed from the RedHat distribution package. - The Linux results were also seen on Fedora Core 7 running Mono 1.9.1 compiled manually from the sources download. Images of the results found on windows (Windows.png), on mono for windows (WinMono.png) and on mono for linux (LinuxMono-5.png) are included in the zip file. Additionally, other rTest rectangle sizes are included (LinuxMono-25.png, LinuxMono-75.png, LinuxMono-300.png) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
