Media Server 23.3

# Region

A region to process, instead of processing the whole image or video frame.

Specify the region as a comma-separated list of values in the order: `left,top,width,height`, followed by the units that you want to use.

- `left` is the distance from the left of the frame to the left edge of the region.
- `top` is the distance from the top of the frame to the top edge of the region.
- `width` is the width of the region.
- `height` is the height of the region.

You can choose the following units:

- `percent` or `%` to use percentages of the image or video dimensions (`left` and `width` as percentages of the width, `top` and `height` as percentages of the height).
- `pixels` or `px` to use numbers of pixels.

Many analysis engines produce records that contain regions, and you might want to process a region that has been identified by another task. To process a region of the image or video that is described in the input track, set `Region=Input`.

Type: | Custom
Default: |
Required: | No
Configuration Section: | TaskName
Example: | To process the central 50% of the width of the frame, and the entire height of the frame:
    Region=25,0,50,100 percent
To process a region 800 pixels wide by 400 pixels high, 50 pixels from the left and top sides of the image or video:
    Region=50,50,800,400 pixels
To process a region described in the input track:
    Region=Input
