LEAD Video Overlay Filter User Interface (2.0)
The Video 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 | Specifies which method to use to control the output size: |
| • Auto: the output size is calculated automatically based on the size of the input streams. The output width/height are the maximum of the input width/height of the input streams. | |
| • Custom: the output size is indicated by the Custom Output Width and Custom Output Height settings. | |
| The default is Auto. | |
| Custom Output Width | Specifies the output width. Used only if the Output Size is set to Custom. If set to 0, the output width is the maximum of input widths. In this case, the width is calculated as if the Output Size was set to Auto. |
| Custom Output Height | Specifies the output height. Used only if Output Size is set to Custom. If set to 0, the output height is the maximum of input heights. 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. |
