Specifies the region to use when cropping the image.
Set this parameter only when you want to specify a fixed region. If you do not set this parameter, Media Server uses the region data in the input record (for example a bounding box around a detected face or object).
To specify a region, set this parameter to a comma-separated list of values in the order: left
,top
,width
,height
.
left
|
is the distance from the left edge of the image to the left edge of the region. |
top
|
is the distance from the top edge of the image to the top edge of the region. |
width
|
is the width of the region. |
height
|
is the height of the region. |
Depending on the setting of the RegionUnit parameter, values are given in either pixels or as percentages of the image dimensions.
