 **Remarks**
 
 The coordinates are typically set in pixels. However, if you are setting a region via the [`SimplifiedCaptureVisionSettings`](../capture-vision-router/simplified-capture-vision-settings.md), you can set the coordinates of the Quadrilateral as percentages (of the frame dimensions) instead of pixels if `roiMeasuredInPercentage` is set to true.
