LEAD Video Image Overlay Filter User Interface (2.0)

The Video Image Overlay Filter property page provides a user interface for changing the filter's attributes.

Changes will be applied directly to the streaming media with the ability to set them permanently by clicking Apply or OK, or to abandon changes by clicking Cancel. Positioning the mouse pointer over a control displays general information for that control. The following table shows the controls and their descriptions:

Control	Description
Overlay image file name browse button	If the Overlay image layer is selected, clicking the browse button opens a MS Windows Open dialog so the user can select an overlay image file.
BK Color button	If the Background color layer is selected, opens a Color dialog so the user can select the background color.
Output Size drop-down list box	Specifies the method used to control the output size: Auto: the output size is the same as the size of the input stream. Custom: the output size is indicated by the Custom Output Width and Custom Output Height settings. The default is Auto.
Custom Output Width spin box	Specifies the output width. Used only if the Output Size is set to Custom. If set to 0, then the output width is the same as the input width. In this case, the width is calculated as if the Output Size was set to Auto.
Custom Output Height spin box	Specifies the output height. Used only if the Output Size is set to Custom. If set to 0, then the output height is the same as the input height. In this case, the height is calculated as if the Output Size was set to Auto.
Layers order list	Contains the available layers. Change the layer order by clicking Send to Back or Send to Front.
Send to back button	Moves the selected layer to the back by one layer.
Send to front button	Moves the selected layer to the front by one layer.
Enable mask image check box	Enables or disables the mask bitmap feature for the selected layer. When the mask bitmap is used for a layer, this layer-s opacity and transparency properties will be ignored.
Mask image file name browse button	If a mask image is being used, opens an MS Windows Open dialog so the mask image can be selected. The mask image must be an 8-bpp gray scale Windows BMP file.
