When exporting a MapView, the size of the output image is based on the Resolution and the Height and Width properties. For example, if the output resolution is 96 and height and width are both 960 then the output image size will be 960 pixels by 960 pixels and 10 inches by 10 inches. The geographic area for an exported MapView is generated based on its Camera location which represents the center of the view.
When exporting a Layout or a MapFrame, the height and width are obtained from the size of the object in page units and the Height and Width properties are ignored. For example, if a MapFrame is 5 inches by 5 inches and the resolution is 300, the output image will be 1500 pixels by 1500 pixels and remain 5 inches by 5 inches.
