719	NAME: tvplus
720
721	PURPOSE: enhanced version of tvscl
722
723	CATEGORY: quick exploration of 2D arrays
724
725	CALLING SEQUENCE: tvplus,z2d [,cellsize]
726
727	INPUTS:
728
729	z2d: 2D array to visualize
730
731	cellsize: (optional) this is the size (in pixel) of the square
732	representing 1 array element. By default, this size is computed
733	automatically in order that the size of the plotting window do
734	not exceed the screen size. If the user specify a large value
735	of cellsize that forces tvplus to create a window larger than
736	the screen, a "scrolling window" will be displayed instead of a
737	regular window. Unfortunately the nice fonctionnalities of tvplus
738	are not coded for "scrolling window" case...
739
740	KEYWORD PARAMETERS:
741
742	BOTTOM: The lowest color index of the colors to be loaded in
743	the bar. default is 0.
744
745	C_NAN: The color number that should be used for the NaN values.
746	default value is !d.n_colors < 255
747
748	C_MASK: The color number that should be used for the mask values.
749	default value is 0
750
751	OFFSET: 2 elements vector used by tvplus itself when shoing zoom.
752	It is used to shift the ranges of xaxis and yaxis.
753	For example: tvplus,sst[x1:x2,y1:y2],offest=[x1,y1]
754
755	MASK: The mask value. Note that if abs(mask) < 1.e6, then the
756	exact value of the mask is used to find the maskwd point.
757	if abs(mask) > 1.e6, the test to find the masked value is ge
758	abs(mask)/10. This is necessary to avoid the rounding errors
759
760	MIN and MAX: scalars used to specify the min and max values
761	of the color bar. default is from 0 to !d.n_colors < 255
762
763	NCOLORS: This is the number of colors in the color
764	bar. default is !d.n_colors<255 -1
765
766	NOINTERP: used this keyword if you don't whant that the values
767	are interpolated between 0 (or min) and !d.n_colors < 255 (or max).
768	This can be for example usefull when working on byte type arrays.
769
770	NOUSEINFOS: activite to supress the printed message explaining
771	how to use tvplus
772
773	WINDOW: Number of the window used to display the array values.
774	default is window number 0.
775
776	OUTPUTS: no (except the printed finformations, see below)
777
778	COMMON BLOCKS: no
779
780	SIDE EFFECTS:
781
782	use your mouse to scan the array values...
783	left button : mouse position and associated array value
784	middle button: use it twice to define a zoom box
785	right button : quit
786
787	RESTRICTIONS: the nice fonctionnalities of tvplus are not coded
788	for "scrolling window" case...
