Stray linework being drawn

[jrizzo]

MapGuide seems to be displaying stray linework when rendering certain DWF files. To reproduce the problem, load the attached dwf into MapGuide and create a layer referencing the sheet "Elmwood Park - RDC1 4th Floor". Examine the layer as it is rendered by mapguide. The drawing is a building floor plan - look in the vicinity of section D-1 of the drawing. There is a curved feature being drawn, passing through the label of office "4-105". If you examine this sheet in Autodesk's Design Review application, that curved feature does not exist in the file. This is not a new issue - I have observed this behavior in every version since MapGuide 1.0. I have also seen this with other DWF files - this is only one example.

Reproduced. Perhaps this will be resolved if we update the DWF Toolkit. We are using 7.1 but 7.6 is available from the Autodesk site.

This is a bug in the MG rendering code. The tilt angle property of the ellipse op-code (the overall rotation of the ellipse / elliptical arc) is not being taken into account. The fix is straightforward, and I will submit it shortly.

Fixed in trunk with r4973.

I am still seeing this behavior in 2.2 with the same data set.

This was only fixed in the trunk stream and not in the 2.2 stream.

If you need it fixed in the 2.2 stream then send an email nominating it and ask someone to port it.

I don't work on the 2.2 stream, so it will have to be someone else.
