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. |
