Polygon
The Polygon function draws a polygon consisting of two or more vertices connected by
straight lines. The polygon is outlined by using the current pen and filled by
using the current brush and polygon fill mode.
BOOL Polygon(
HDC hdc,
| // handle to device context
| CONST POINT *lpPoints,
| // pointer to polygon's vertices
| int nCount
| // count of polygon's vertices
| );
|
|
Parameters
hdc
Identifies the device context.
lpPoints
Points to an array of POINT structures that specify the vertices of the polygon.
nCount
Specifies the number of vertices in the array. This value must be greater than
or equal to 2.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The polygon is closed automatically by drawing a line from the last vertex to
the first.
The current position is neither used nor updated by the Polygon function.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
