Rotated Layers

Aug 22, 2011 at 4:07 PM

Im pretty new to MapWinGIS.

And the documentation I could find was pretty light. I'd like to know if there's a way rotate a shape or image layer? by an arbitrary angle?

There is no function for shape rotation in MapWinGIS. But it can be easily implemented.

It's possible to rotate (more correctly to say, transform) GDAL-based images (non-bmp) by setting parameters of world file.

It's possible to rotate symbols for point layers, icons for example (ShapeDrawingOptions.PointRotation).

It's possible to set rotation angle for the whole map (Map.MapRotationAngle), though there are certain limitations.
