'''Package:''' [[Package SignalLabBasicPkg|SignalLabBasicPkg]]

'''Unit:''' [[Unit IGDIPlus|IGDIPlus]]

== Syntax ==
=== Delphi: ===
<code>
'''type''' IGPRegion = '''interface'''
</code>
== Summary ==
Interface to a [[Class IGDIPlus.TGPRegion|TGPRegion]] object.

== Description ==
Defines interface to a [[Class IGDIPlus.TGPRegion|TGPRegion]] object.

The [[Class IGDIPlus.TGPRegion|TGPRegion]] class describes an area of the display surface.
The area can be any shape. In other words, the boundary of
the area can be a combination of curved and straight lines.
Regions can also be created from the interiors of rectangles,
paths, or a combination of these. Regions are used in
clipping and hit-testing operations.
Remarks
A GDI+ region is stored in world coordinates whereas a GDI
region is stored in device coordinates. Therefore, a GDI+
region is scalable and a GDI region is not. For more
information, see Scalable Regions

An application can use regions to clip the output of drawing
operations. The Window Manager uses regions to define the
drawing area of windows. These regions are called clipping
regions. An application can also use regions in hit-testing
operations, such as checking whether a point is in a region
or whether a rectangle intersects a region. For more
information, see "Regions", "Clipping", and "Using Regions"
on MSDN.
