NAME
d.label - Creates and displays text labels
in the active display frame on the graphics monitor.
(GRASS Display Program)
SYNOPSIS
d.label
d.label help
d.label
[size=value]
[backcolor=name]
[textcolor=name]
[font=name]
DESCRIPTION
d.label allows the user to create and display text
labels in the active frame on the graphics monitor. It
interactively requests that the user type in text and use
the pointing device (mouse) to identify where this text is
to be placed within the active graphics frame. The program
will prompt the user for label size, background color, text
color, and text font type, if the user fails to specify
these values on the command line. Program prompts use the
standard GRASS parser
interface.
Parameters:
- size=value
- Sets the label text size to the specified number.
Values are stated as a percentage of the frame height;
e.g., a size of 10 will make each line of text equal to
one-tenth the height of the display frame.
Options: 0-1000
Default: 10
- backcolor=name
- Sets the color of the label background to the name stated.
Options: red, orange, yellow, green, blue, indigo,
violet, gray, white, and black.
Default: black
- textcolor=name
- Sets the color of the label text to the name stated.
Options: same as for backcolor.
Default: white
- font=name
- Sets the font type used for the label's text to name.
Options: romand, romanp, romant, romans, scriptc, scripts,
romancs, italicc, italiccs, gothitt, gothgrt, and gothgbt.
The user can view these available fonts by running
show.fonts.sh.
Default: romans (Roman simplex font type), or
whatever font the user has set the font type to before
entering d.label.
NOTES
This program will allow the user to display labels anywhere in the active
display frame, even in areas lying outside of the current geographic region.
d.label will only allow the user to type in one
line of text. The fully interactive program
d.labels
can be used to
create text labels having as many as four lines.
d.label does not create paint labels files displayable by
d.paint.labels --
d.labels
does.
These programs should be integrated in future GRASS releases.
BUGS
If the user is running GRASS under X Windows, and the user
enters a text label longer than 80 characters (i.e., allows
text to wrap onto a second line), X Windows will stop the
user's GRASS graphics monitor without throwing the user out
of GRASS. If this happens, the user should simply restart
a graphics monitor, using
d.mon.
