Pie
The Pie function draws a pie-shaped wedge bounded by the intersection of an ellipse
and two radials. The pie is outlined by using the current pen and filled by
using the current brush.
BOOL Pie(
HDC hdc,
| // handle to device context
| int nLeftRect,
| // x-coord. of bounding rectangle's upper-left corner
| int nTopRect,
| // y-coord. of bounding rectangle's upper-left corner
| int nRightRect,
| // x-coord. of bounding rectangle's lower-right corner
| int nBottomRect,
| // y-coord. of bounding rectangle's lower-right corner
| int nXRadial1,
| // x-coord. of first radial's endpoint
| int nYRadial1,
| // y-coord. of first radial's endpoint
| int nXRadial2,
| // x-coord. of second radial's endpoint
| int nYRadial2
| // y-coord. of second radial's endpoint
| );
|
|
Parameters
hdc
Identifies the device context.
nLeftRect
Specifies the x-coordinate of the upper-left corner of the bounding rectangle.
nTopRect
Specifies the y-coordinate of the upper-left corner of the bounding rectangle.
nRightRect
Specifies the x-coordinate of the lower-right corner of the bounding
rectangle.
nBottomRect
Specifies the y-coordinate of the lower-right corner of the bounding
rectangle.
nXRadial1
Specifies the x-coordinate of the endpoint of the first radial.
nYRadial1
Specifies the y-coordinate of the endpoint of the first radial.
nXRadial2
Specifies the x-coordinate of the endpoint of the second radial.
nYRadial2
Specifies the y-coordinate of the endpoint of the second radial.
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 curve of the pie is defined by an ellipse that fits the specified bounding
rectangle. The curve begins at the point where the ellipse intersects the
first radial and extends counterclockwise to the point where the ellipse intersects
the second radial. (A radial is a line drawn from the center of the ellipse to the specified endpoint on
the ellipse.)
The current position is neither used nor updated by the Pie function.
Windows 95: The sum of the coordinates of the bounding rectangle cannot exceed 32,767.
The sum of nLeftRect and nRightRect or nTopRect and nBottomRect parameters cannot exceed 32,767.

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 » |
