GetNearestPaletteIndex
The GetNearestPaletteIndex function retrieves the index for the entry in the specified logical palette
most closely matching a specified color value.
UINT GetNearestPaletteIndex(
HPALETTE hpal,
| // handle of logical color palette
| COLORREF crColor
| // color to be matched
| );
|
|
Parameters
hpal
Identifies a logical color palette.
crColor
Specifies a color to be matched.
Return Values
If the function succeeds, the return value is the index of an entry in a
logical palette.
If the function fails, the return value is CLR_INVALID. To get extended error
information, call GetLastError.
Remarks
An application can determine whether a device supports palette operations by
calling the GetDeviceCaps function and specifying the RASTERCAPS constant.
If the given logical palette contains entries with the PC_EXPLICIT flag set,
the return value is undefined.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

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 » |
