**+a**\ *angle*
For annotations at a fixed angle, **+an** for contour-normal, or
**+ap** for contour-parallel [Default]. For **+ap**, you may optionally
append **u** for up-hill and **d** for down-hill cartographic annotations.
**+c**\ *dx*\ [/*dy*]
Sets the clearance between label and optional text box. Append
**c**\ \|\ **i**\ \|\ **p** to specify the unit or % to indicate a
percentage of the label font size [15%].
**+d**
Turns on debug which will draw helper points and lines to illustrate
the workings of the contour line setup.
**+e**
Delay the plotting of the text. This is used to build a clip path
based on the text, then lay down other overlays while that clip path
is in effect, then turning of clipping with psclip **-Cs** which
finally plots the original text.
**+f**\ *font*
Sets the desired font [Default **FONT\_ANNOT\_PRIMARY** with its
size changed to 9p].
**+g**\ [*color*\ ]
Selects opaque text boxes [Default is transparent]; optionally
specify the color [Default is **PS\_PAGE\_COLOR**].
**+j**\ *just*
Sets label justification [Default is MC].
**+n**\ *dx*\ [/*dy*]
Nudges the placement of labels by the specified amount (append
**c**\ \|\ **i**\ \|\ **p** to specify the units). Increments
are considered in the coordinate system defined by the
orientation of the contour; use **+N** to force increments in the
plot x/y coordinates system [no nudging]. Not allowed with **+v**.
**+o**
Selects rounded rectangular text box [Default is rectangular].
Not applicable for curved text (**+v**) and only makes sense for
opaque text boxes.
**+p**\ [*pen*\ ]
Draws the outline of text boxes [Default is no outline];
optionally specify pen for outline [Default is width = 0.25p,
color = black, style = solid].
**+r**\ *min\_rad*
Will not place labels where the contours's radius of curvature is
less than *min\_rad* [Default is 0].
**+t**\ [*file*\ ]
Saves contour label x, y, angle, and text to *file* [Contour\_labels.txt].
**+u**\ *unit*
Appends *unit* to all contour labels. [Default is no unit].
If **z** is appended we use the z-unit from the grdfile.
**+v**
Specifies curved labels following the contour [Default is straight
labels].
**+w**
Specifies how many (*x*,\ *y*) points will be used to estimate
label angles [automatic].
**+=**\ *prefix*
Prepends *prefix* to all contour labels. [Default is no prefix].
