.SH DESCRIPTION
.IX Header "DESCRIPTION"
Given a camera model (or models), this tool displays the valid-intrinsics
region(s). All the given models MUST contain a valid-intrinsics region. Empty
regions are handled properly.
.PP
If an image is given, the region is rendered overlaid onto the image.
.PP
If \-\-points then we also read x,y points from STDIN, and plot those too.
.PP
By default, we use gnuplotlib to make an interactive plot. Alternately, pass
\&\-\-write\-image to annotate a given image, and write the new image on disk.
.PP
\&\-\-write\-image is not supported together with \-\-points.
