LAnimationWindow::SetBitmapList
#include "ltwrappr.h"
L_VOID LAnimationWindow::SetBitmapList(pBitmapList, pBitmapListPrev=NULL, nBitsPerPixel=0, nColorOrder=ORDER_BGRORGRAY)
LBitmapList * pBitmapList; |
/* pointer to an LBitmapList object */ |
LBitmapList * pBitmapListPrev; |
/* pointer to an LBitmapList object */ |
L_INT nBitsPerPixel; |
/* the number of bits per pixel for the playback bitmap */ |
L_INT nColorOrder; |
/* color order of the playback bitmap */ |
Provides a way to overwrite the internal bitmap list of an LAnimationWindow object.
Parameter |
Description |
|
pBitmapList |
Pointer to an LBitmapList object. This is the new bitmap to attach to the LAnimationWindow object. |
|
pBitmapListPrev |
Pointer to an LBitmapList object to hold the previous bitmaplist used by the LAnimationWindow object. |
|
nBitsPerPixel |
Number of bits per pixel for the playback bitmap. |
|
nColorOrder |
Color order of the playback bitmap. Possible values are: |
|
|
Value |
Meaning |
|
ORDER_RGB |
[0] The input colors are in red-green-blue order. |
|
ORDER_BGR |
[1] The input colors are in blue-green-red order. |
|
ORDER_GRAY |
[2] 12 or 16-bit grayscale image. 12 and 16-bit grayscale images are only supported in the Document/Medical toolkits. |
Returns
None
Comments
The pBitmapList must point to a valid LBitmapList object. If you want to get the previous bitmap list used by the LAnimationWindow object, pass a valid pointer to an LBitmapList object in the pBitmapListPrev parameter. If you do this, you must destroy the LBitmapList object yourself when it is no longer needed. Passing NULL for pBitmapListPrev will cause the previous LBitmapList object to be destroyed by the LAnimationWindow object.
