ZeeImage Control Message

ZIM_GETIMAGEWIDTH

ZIM_GETIMAGEWIDTH

An application sends a ZIM_GETIMAGEWIDTH to retrieve the width dimension of the specified image in the ZeeImage image list. The image will be autosized (shrunk) to fit in the client area of the ZeeImage control. This message will return the actual dimensions of the image before any resizing is done by the control to display it.
