ZeeImage Control Message

ZIM_SETEXPAND

ZIM_SETEXPAND

An application sends a ZGM_SETEXPAND message to change the way images that are smaller in resolution than the client area of the ZeeImage control are displayed in the control. When the EXPAND attribute of the image is set to FALSE, a small image is only displayed as its image resolution or smaller.
