Hello,

Raster Imaging Pro V15
VC++

In my project , I used "LBitmapWindow" class. Now I want to set the bitmap's destination rectangle. But I found the Comments in “SetDstRect" function that "This function is not working while being called from the classes LBitmapWindow" .
How can I do?

Thanks

aspire

Aspire,
If you want to change the destination rectangle to control the scroll position, you can do it as follows:

1. When you have the scroll position you want to save:
m_LBitmapWnd.GetRects(NULL, NULL, &dr, NULL); //only want the dest rect.

2. When you want to scroll to the old position:
m_LBitmapWnd.ScrollTo(-dr.left, -dr.top);
