NAME
Ngmisc_params - This document briefly describes all Ngmisc internal parameters.
DESCRIPTION
Parameter descriptions, in alphabetical order, of all Ngmisc internal parameters follow.
Each entry includes the name of a parameter, its FORTRAN type, its default value, and a
short description of the parameter.
´CA´ - Integer - 1
This parameter controls the type of line cap used in PostScript output from NCAR
GKS. If the value is 0, butt caps are used; if the value is 1, round caps are
used; if the value is 2, projecting square caps are used. This value applies to
the specific workstation specified in a previous call to NGSETI to set a value for
the ´WO´ parameter (see below).
´CL´ - Integer - 1
Specifies whether clipping to NDC space is on in NCAR GKS. A value of "1" will
turn clipping on and a value of "0" will turn it off. This flag controls whether
filled areas and polylines are clipped if they go out of the world coordinate
rectangle that gets mapped onto NDC space. This clipping is not to be confused
with the clipping that is controlled by the GKS GSCLIP function - that function
controls whether clipping is to be done to the viewport of the current
normalization transformation, not to NDC space itself (unless the viewport of the
current normalization transformation is the entirety of NDC space).
´CM´ - Integer - 1
If CM equals 1, then the RGB color model is used for PostScript output; if CM
equals 0, then the CMYK color model is used for PostScript output.
´CO´ - Integer - 25
A positive integer specifying a scale factor for the integer coordinate values in
PostScript output from NCAR GKS. This value will apply to the first PostScript
workstation opened with GOPWK after specifying the value for ´CO´. The default
coordinates in PostScript user space represent units of 1/72 of an inch; for an 8
1/2 inch by 11 inch page in portrait mode, the default PostScript user coordinate
space is 0 to 612 in X and 0 to 792 in Y. The value of ´CO´ will multiply
the PostScript user coordinates by the specified amount. Specifying larger values
for CO will increase the accuracy of coordinate positions at the expense of larger
files (more space is needed to represent the larger integer coordinate values);
smaller numbers reduce the accuracy of coordinate positions, but reduce file sizes.
´CT´ - Integer - 0
Specifies whether NGDOTS will draw filled dots or circles. If the value of CT is
0, then filled dots are drawn. If the value of CT is not 0, then circles are
drawn.
´ER´ - Integer - 10
Specifies the maximum number of error messages that will be issued by NCAR GKS
before it terminates execution. ER must be larger than zero.
´FI´ - Real - 0.0005
A real number in the range 0. to 1. (normalized device coordinate space) that
specifies the spacing between fill lines used in software fill in PostScript output
from NCAR GKS. This value applies to the specific workstation specified in a
previous call to NGSETI to set a value for the "WO" parameter (see below).
´FU´ - Integer - 0
Controls whether the background color is applied to the entirety of a page, or just
the viewport area, in PostScript output from NCAR GKS. If the value is 0, then the
background color applies only to the viewport area; if the value is non-zero, then
the background color covers the entire page. This value applies to the specific
workstation specified in a previous call to NGSETI to set a value for the ´WO´
parameter (see below).
´HA´ - Real - 0.01
A real number in the range 0. to 1. (normalized device coordinate space) that
specifies the spacing between hatch lines used in hatch-pattern filled areas in
PostScript output from NCAR GKS. This value applies to the specific workstation
specified in a previous call to NGSETI to set a value for the ´WO´ parameter (see
below).
´IG´ - Integer - 0
A flag to indicate whether the clip rectangles in segment copies should be
transformed by using the current segment transformation. The GKS standard says
that the clip rectangles should not be so transformed and this is the default.
´JO´ - Integer - 1
Controls the type of line join used in PostScript output from NCAR GKS. If the
value is 0, miter joins are used; if the value is 1, round joins are used; if the
value is 2, bevel joins are used. This value applies to the specific workstation
specified in a previous call to NGSETI to set a value for the ´WO´ parameter (see
below).
´LB´ - Integer - 1
Specifies the secondary logo color (this is applicable only for logo type 5, in
which case the secondary color is used for the text string "UCAR").
´LC´ - Integer - 1
Specifies the logo color (except in the case of an NCAR logo being plotted to a
PostScript workstation, in which case you will get the full-color logo).
´LT´ - Integer - 1
Specify the logo type. See the documentation for NGLOGO for a list of the logo
types, or execute "ncargex miex01" for an example plot that lists the logo types.
´LX´ - Integer - 36
Specifies the left X coordinate value to be used in positioning PostScript output
from NCAR GKS on the output page. This value is in the default PostScript user
space where one unit corresponds to 1/72 inch. This value must be specified before
opening the PostScript workstation to which it will apply. See descriptions for
the parameters ´LY´, ´UX´, and ´UY´.
´LY´ - Integer - 126
Specifies the lower Y coordinate value to be used in positioning PostScript output
from NCAR GKS on the output page. This value is in the default PostScript user
space where one unit corresponds to 1/72 inch. This value must be specified before
opening the PostScript workstation to which it will apply. See descriptions for
the parameters ´LX´, ´UX´, and ´UY´.
´MC´ - Integer - depends on the workstation type
The X11 workstation indicated by the integer should use a "mixed" X color model.
(-1) indicates the next X11 workstation created.
´ME´ - Character - depends on the workstation type
A character string that specifies the metafile name that will be used by the next
NCAR GKS GOPWK call that opens a GKS CGM or PostScript workstation.
´MI´ - Real - 10.
Controls the miter limit of line joins in PostScript output from NCAR GKS. This
applies only if line joins are specified as mitered joins (see the description of
the parameter ´JO´ above). This value applies to the specific workstation
specified in a previous call to NGSETI to set a value for the ´WO´ parameter (see
below).
´NO´ - Real - 1.0
A positive real number specifying a scale factor for the nominal linewidth in
PostScript output from NCAR GKS. Setting the value larger than 1.0 will result in
all line thicknesses being fatter by that amount; setting the value smaller than
1.0 will result in all line thicknesses being narrower by that amount. This value
applies to the specific workstation specified in a previous call to NGSETI to set a
value for the ´WO´ parameter (see below).
´OS´ - Real - 0.07
Specifies the logo size in normalized device coordinates (a number between 0. and
1.). For example, a size specification of 0.1 would give a logo size one-tenth the
maximum plot height.
´OX´ - Real - 0.93
Specify the logo X-coordinate position in normalized device coordinates.
´OY´ - Real - 0.05
Specify the logo Y-coordinate position in normalized device coordinates.
´PA´ - Integer - 1300
Specifies the maximum size of paths used in PostScript output from NCAR GKS. This
value controls when software fill will be used in place of hardware fill. Larger
values result in significant file size and interpretation time savings. This value
applies to the specific workstation specified in a previous call to NGSETI to set a
value for the ´WO´ parameter (see below). The default value is compatible with the
minimum value specified in the Adobe PostScript specifications that is to apply to
all PostScript interpreters. A specific interpreter may allow for significantly
larger paths. See the documentation for your local PostScript interpreter to
determine this value.
´PC´ - Integer - depends on the workstation type
The X11 workstation indicated by the integer should use a "private" X color model.
(-1) indicates the next X11 workstation created.
´PE´ - Integer - 20
Percentage error allowed in matching requested colors in X Window output where the
window shares a single color map with all the other current X windows. The value
"0" is special and is the same as the value "100" meaning that any color may be
selected. In the default environment all X11 windows share a single color map and
when a request is made to allocate a new color, and there are no more colors left,
then the nearest color (to within the stated percentage) is selected. The "nearest
color" is the one in the current color table that is closest using the normal
distance metric in the RGB color cube. The percentage error is measured as a
percentage of lenght of a diagonal of the RGB color cube.
´PH´ - Integer - 792
Specification, in points, of the PDF output page height.
´PI´ - Character - blanks
A character string that will be used for the picture name of the current picture in
the PICTURE NAME element of an ncgm file. The first picture must be named before
the ncgm workstation is opened and subsequent pictures must be named immediately
after creating the previous picture. Not all pictures need be named and any
picture that is not assigned a specific name is assigned blanks in the PICTURE NAME
field of the ncgm.
´PW´ - Integer - 612
Specification, in points, of the PDF output page width.
´SC´ - Integer - depends on the workstation type
The X11 workstation indicated by the integer should use a "shared" X color model.
(-1) indicates the next X11 workstation created.
´SH´ - Integer - 612
Specification, in points, of the PS output page height.
´SE´ - Character - 'GSEG'
Specifies a root name for segments created by NCAR GKS. In the default case, the
segment name used will be constructed from GSEG by appending an integer constructed
from the user id, the process id, and the segment number. By default, the segments
are stored in the directory specified by the environment variable TMPDIR (usually
set internally at install time to /tmp). If SE is changed away from the default
setting, then the segment name will be cunstructed using the value of SE as a root
and appending the segment number.
´SW´ - Integer - 792
Specification, in points, of the PS output page width.
´SS´ - Integer - 1
Specifies whether segments should be deleted when WISS is closed. The default is
to delete segments. Setting SS to a non-default value will cause segments to be
saved.
´ST´ - Integer - 200
Specifies the maximum size of the operand stack used in PostScript output from NCAR
GKS. The primary effect of setting this value controls how many points can be
included in a locally-defined macro for polylines and filled areas. Larger values
result in space savings. This value applies to the specific workstation specified
in a previous call to NGSETI to set a value for the ´WO´ parameter (see below).
The default value is compatible with the minimum value specified in the Adobe
PostScript specifications that is to apply to all PostScript interpreters.
´UX´ - Integer - 576
Specifies the upper X coordinate value to be used in positioning PostScript output
from NCAR GKS on the output page. This value is in the default PostScript user
space where one unit corresponds to 1/72 inch. This value must be specified before
opening the PostScript workstation to which it will apply. See descriptions for
the parameters "LX", "LY", and "UY".
´UY´ - Integer - 666
An integer that specifies the upper Y coordinate value to be used in positioning
PostScript output from NCAR GKS on the output page. This value is in the default
PostScript user space where one unit corresponds to 1/72 inch. This value must be
specified before opening the PostScript workstation to which it will apply. See
descriptions for the parameters "LX", "LY", and "UX".
´WO´ - Integer - none
An integer specifying the NCAR GKS workstation ID that will be used for subsequent
parameters that apply to a specific workstation.
