As stated in the manual, the TVRD() function returns the entire
contents of the current graphics window if no parameters are
provided. You can use the REBIN(), CONGRID() or EXPAND() routines
to enlarge the array if desired.

You can use

array = tvrd( x0, y0, nx, ny )

to read the contents of the graphics window starting at (x0,y0)
(the lower-left corner); nx and ny specify the size of the
rectangle in columns and rows.

Hope this helps.
