LBitmapBase::TranslateColor

#include "ltwrappr.h"

virtual COLORREF LBitmapBase::TranslateColor(LBitmapSrc, crColor)

LBitmapBase& LBitmapSrc;	/* the source bitmap object */
COLORREF crColor;	/* the color in the source bitmap */

Translates the specified color in the source class object's bitmap, and returns the nearest matching color in the calling object's bitmap.

Parameter	Description
LBitmapSrc	The source bitmap object.
crColor	The COLORREF value that specifies the color in the source bitmap to be translated. You can get the value from a palette entry or by using LBitmapBase::GetPixelColor.

Returns

The COLORREF value or the palette index of the nearest matching color in calling object's bitmap. If the calling object's bitmap is 8 bits per pixel or less, this is always the palette index. Otherwise, it is the COLORREF value.

Comments

When creating a target bitmap for animation, you can use this function to ensure that the correct color is specified as the background color.

Note:

The LBitmapSrc paramater is passed by reference, and is a required parameter.
