MV Bitmap Overlay DirectShow Filter
The MontiVision Bitmap Overlay filter overlays an image onto the output video stream. Either a colour for the transparent background is specified, a constant alpha value for the whole image is used or both modes are active simultaneous. If a background colour is specified, every pixel with this colour is set as transparent. If a constant alpha value is used, the output video is calculated as follows: Output = Input * Alpha + Overlay * (255-Alpha). The overlaid image can be repositioned and resized.
The filter uses the FreeImage library to load the images. Some of the supported types are: BMP, GIF, JPG, PNG, TIF, ....

| CLSID: | CLSID_MVBitmapOverlay |
Interface
Supported COM Events
The filter supports following events through the IMVFilterEvents interface. Look at the filter events page for more information.
| Event |
Value |
Description |
| MV_ALGORITHM_START_EVENT |
0 |
A filter starts processing a video frame or sample. |
| MV_ALGORITHM_END_EVENT |
1 |
A filter finishes processing a video frame or sample. |
MV Bitmap Overlay Property Page
Uses the IMVBitmapOverlay configuration interface.
| Enable | Enables or disables the bitmap overlay. |
| Transparent background | A transparent background is used. Every pixel with a specified colour is set as transparent. |
| Constant image alpha | A constant alpha value is used for every pixel of the image. |
| Both modes | a transparent background an a constant alpha value are used at the same time. |
| Background colour | The currently selected background colour. |
| Video alpha value |
Output pixel value = Input pixel value
* Alpha
+ |
| Relative Position | Places the image within the selected corner. |
| Absolute Position | Places the image exactly at the defined position relative to the upper left corner of the video stream. |
| Current bitmap | Used to specify the overlay image and show the current filepath. |
| Enable resize | Enables or disables the other resize controls. The original size of the overlay image will be restored, if it's unchecked. |
| Maintain aspect ratio | If this box is checked, the aspect ratio of the overlay image will be kept. |
| Width | Changes the width of the overlay image. |
| Height | Changes the height of the overlay image. |
