Enhanced Rendering with GDI+ Translucency and Anti-Aliasing

Microsoft Windows GDI+ is the portion of the Windows XP operating system or Windows Server
2003 operating system that provides two-dimensional vector graphics, imaging, and typography.
GDI+ improves on Windows Graphics Device Interface (GDI, the graphics device interface included
with earlier versions of Windows) by adding new features and optimizing existing features. GDI+
rendering in MapXtreme allows you to create translucent labels, themes, and layers, as well as
apply anti-aliasing that will smooth the jagged edges of lines, curves, and region borders when
representing a high-definition rendition at a lower resolution.

You can enable GDI+ rendering in the API through two new properties— EnableTranslucency and
SmoothingMode— in the MapInfo.Mapping.DrawingAttributes and
MapInfo.Mapping.LegendDrawing Attributes classes. You can also enable these properties using
the Style tab in Workspace Manager’s Layer Control.
