SetPaletteEntries function

The SetPaletteEntries function sets RGB (red, green, blue) color values and flags in a range of entries in a logical palette.

Syntax


UINT SetPaletteEntries(
  _In_  HPALETTE hpal,
  _In_  UINT iStart,
  _In_  UINT cEntries,
  _In_  const PALETTEENTRY *lppe
);

Parameters

hpal [in]

A handle to the logical palette.

iStart [in]

The first logical-palette entry to be set.

cEntries [in]

The number of logical-palette entries to be set.

lppe [in]

A pointer to the first member of an array of PALETTEENTRY structures containing the RGB values and flags.

Return value

If the function succeeds, the return value is the number of entries that were set in the logical palette.

If the function fails, the return value is zero.

Remarks

An application can determine whether a device supports palette operations by calling the GetDeviceCaps function and specifying the RASTERCAPS constant.

Even if a logical palette has been selected and realized, changes to the palette do not affect the physical palette in the surface. RealizePalette must be called again to set the new logical palette into the surface.
