#!EF #!EF #!I50 #!N is the caption to be displayed. This
parameter can also be a list of strings, for a multiline
caption. Alternatively, you can separate substrings for a multiline caption by
using \n. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* position #!EF #!EF #!I50
#!N specifies the position of the caption in units determined by
#!F-adobe-times-bold-r-normal--18* flag #!EF (see below). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* flag
#!EF #!EF #!I50 #!N determines the type of coordinates used in

placed at #!F-adobe-times-bold-r-normal--18* position #!EF : #!N #!N [0 0] =
bottom left of the caption #!N [1 1] = top right
#!N #!N If #!F-adobe-times-bold-r-normal--18* flag #!EF = 0, the default is
the same as the current specification of #!F-adobe-times-bold-r-normal--18* position #!EF .
#!N #!N If #!F-adobe-times-bold-r-normal--18* flag #!EF = 1, the default is
the lower left corner of the caption. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18*
#!F-adobe-times-bold-r-normal--18* alignment #!EF #!EF #!I50 #!N determines the alignment of a
multiline caption from left justified (0.0) to right justified (1.0). For
intermediate values, justification is defined by linear interpolation (e.g., a value
of 0.5 centers the lines). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* height
#!EF #!EF #!I50 #!N determines the height of the caption characters
in pixels. A negative value generates an inverted caption. #!N #!I0
#!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* font #!EF #!EF #!I50 #!N specifies the font
for a displayed caption. You can specify any of the defined
fonts supplied with Data Explorer. These include a variable-width font ("variable,"
the default) and a fixed-width font ("fixed"): #!CForestGreen #!N #!N #!F-adobe-courier-bold-r-normal--18*

#!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* direction #!EF #!EF #!I50 #!N determines the orientation of
the caption (i.e., the direction of its baseline). #!N #!I0 #!N
#!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* up #!EF #!EF #!I50 #!N determines the direction of

#!N #!I0 #!N Notes: #!N #!I30 #!N 1. To change the
color of a caption, use the Color module (see #!Lcolor,dxall792 h Color #!EL ).
#!N #!I30 #!N 2. If you are using Render or Display
to render an object which contains a caption, when you change
the resolution of the camera the size of the caption in
pixels will not change. If you want the caption to take
up the same proportion of the image, use the ScaleScreen module
to change the size of the caption. #!I0 #!N #!N #!N
