== Description ==<br />
Defines interface to a TGPRegion object.<br />
<br />
The TGPRegion class describes an area of the display surface.<br />
The area can be any shape. In other words, the boundary of<br />
the area can be a combination of curved and straight lines.<br />
Regions can also be created from the interiors of rectangles,<br />
paths, or a combination of these. Regions are used in<br />
clipping and hit-testing operations.<br />
Remarks<br />
A GDI+ region is stored in world coordinates whereas a GDI<br />
region is stored in device coordinates. Therefore, a GDI+<br />
region is scalable and a GDI region is not. For more<br />
information, see Scalable Regions<br />
<br />
<br />
<br />
An application can use regions to clip the output of drawing<br />
operations. The Window Manager uses regions to define the<br />
drawing area of windows. These regions are called clipping<br />
regions. An application can also use regions in hit-testing<br />
operations, such as checking whether a point is in a region<br />
or whether a rectangle intersects a region. For more<br />
information, see "Regions", "Clipping", and "Using Regions"<br />
