spatial bounds of a mapImage
The four corners are enough - the grid is regular, so nothing lies outside them. A rotated grid still gives an axis aligned bounding box, as it does for an EBSD map.
Syntax
[xmin, xmax, ymin, ymax] = extent(mg)
ext = extent(mg)
ext = extent(mg,ind)Input
| mg | mapImage |
| ind | which components of the combined form to return |
Output
| xmin xmax ymin ymax | bounds |
| ext | [xmin xmax ymin ymax zmin zmax], as for EBSD |
