This method retrieves the index for the entry in the specified logical palette that most closely matches a specified color value.

Syntax

static WINGDIAPI unsigned int WINAPI GetNearestPaletteIndex_I(
  HPALETTE hpal, 
  COLORREF crColor
);

Parameters

  • hpal

Return Value

The index of an entry in a logical palette indicates success.

CLR_INVALID indicates failure.

Remarks

This method is an internal version of the GetNearestPaletteIndex function.

An application can determine whether a device supports palette operations by calling the Gdi::GetDeviceCaps_I method and specifying the RASTERCAPS constant.

If the given logical palette contains entries with the PC_EXPLICIT flag set, the return value is undefined.
