When exporting image to disk, options should include the ability to resize
- by a resize factor (e.g. reduction to 50%, or enlargement to 200%).
- by an unoriented bounding box (e.g. long side max 1920 pixels and short side max 1080 pixels). A source image is resized to fit both sides of the resulting image within the bounding box dimensions, regardless of image orientation.
- by an horizontal-vertical bounding box (e.g. horizontal side 1920 pixels and vertical sides 1080 pixels). A source image is resized to fit both sides of the resulting image within the horizontal and vertical bounding box dimensions.
