Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.

GetDrawingExtent(RectangleShape, Double, Double)

<!– static –> This method returns an adjusted extent based on the ratio of the screen width and height.

Remarks

This function is used because the extent to draw must be the rame ratio as the screen width and height. If they are not, then the image drawn will be stretched or compressed. We always adjust the extent upwards to ensure that no matter how we adjust it, the original extent will fit within the new extent. This ensures that everything you wanted to see in the first extent is visible and maybe a bit more.

ZoomOutToCenter(RectangleShape, Int32, Double, Double, Double, Double)

<!– static –> This method returns an extent that is centered and zoomed out.

Overloads

This overload allows you to pass in the height and width in screen coordinates, as well as a screen X & Y.

Remarks

The resulting rectangle will already be adjusted for the ratio of the screen. You do not need to call GetDrawingExtent afterward.
