L_INT LAnimationWindow::SetAt(nIndex, pBitmap, bReflectIndex = FALSE)
L_UINT nIndex; |

Overwrites the internal bitmap handle of a bitmap in a list. Use this function with LAnimationWindow::GetAt to manipulate a bitmap in a list.
Parameter |
Description |
|
nIndex |
Position of the bitmap in the list. Use zero-based indexing. For example, if there are 10 bitmaps in a list, the index of the last one is 9. |
|
pBitmap |
Pointer to the bitmap handle that will overwrite the internal bitmap handle in the list. |
|
bReflectIndex |
Flag that indicates whether to set the class object's current index to the passed index. Possible values are: |
|
|
Value |
Meaning |
|
TRUE |
Set the class object's current index to the passed index. |
|
FALSE |
Do not set the class object's current index to the passed index. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
When a bitmap is in a list, you do not have direct access to the bitmap handle. Therefore, to do any image processing, you must first use LAnimationWindow::GetAt to get a copy of the internal handle, then do the image processing, then update the internal handle using LAnimationWindow::SetAt.
You cannot use this method to update a bitmap list while it is being used in an animation playback.
