is an option for cells that specifies the size and position of the bounding box within which a graphic is rendered.}})

OpenersNotesSection(Spacer1)Details

With the default setting (RefLink[ImageRegion, paclet:ref/ImageRegion])->{{0,1},{0,1}}, the bounding box of the graphic coincides with the viewing rectangle for the image. The size and position of the viewing rectangle is determined by the settings for (RefLink[ImageSize, paclet:ref/ImageSize]) and (RefLink[ImageMargins, paclet:ref/ImageMargins]).

By changing the value of (RefLink[ImageRegion, paclet:ref/ImageRegion]), you can select a specific region of a graphic for viewing. This option is specified as (RefLink[ImageRegion, paclet:ref/ImageRegion])->{{l,r},{b,t}}, where {l,r} and {b,t} specify the coordinates of the bottom left and top right corners of the bounding box of the graphic.

The size of the graphic scales according to the size of the bounding box. Hence, you can use this option for zooming in or zooming out. If the bounding box you specify is larger than the image size, only the part of the graphic that fits within the viewing rectangle for the image is displayed.

The numbers l, r, b, and t can take any positive or negative value, subject to the constraint that the aspect ratio of the graphic, which is equal to ((b - t)/(l - r)), is always preserved.
