What’s New in the Autodesk MapGuide Viewer API Help .
Autodesk DWG Data Source Support
Several changes and additions have been made to Autodesk MapGuide and
the Autodesk MapGuide Viewer API to support Autodesk drawing (DWG)
data sources. The most significant addition is a new
MGDwgDataSources
object with several methods and properties to get and set DWG values of
Autodesk MapGuide map layers. Also, a new
MGMapLayerSetup
method
(
getDwgDataSources
) and a property (
MGDwgDataSources
) were added.
Two
MGMapLayerSetup
methods (g
etDataFile
and
setDataFile
)
methods and one property (
DataFile
) were also changed to support DWG
data sources. See “DWG Filtering Application” on page 164 for an example
of working with DWG data sources.
Enhanced Support for Map Redraw Operations
Two new
MGMap
methods (
getIntermediateUpdatesEnabled
and
setIntermediateUpdatesEnabled)
and a new property
(
IntermediateUpdatesEnabled
) were added to allow more control over
how frequently, and under what conditions, the Autodesk MapGuide Viewer
redraws a map. Maps are now updated every 1.5 seconds by default. This
allows the end user to view changes to the map as it is being drawn instead
of waiting until the entire map is rendered. See “Handling Busy State and
Map Refresh” on page 43 for information about controlling map refresh
operations.
Symbol Bitmap Support
Changes were made to two
MGSymbolAttr
methods (
setRotation
and
setSymbol
) and two properties (
Rotation
and
Symbol
) to support bitmaps
in symbols.
