aspect, in, optional, type=float
Set this keyword to create a window with this aspect ratio (ysize/xsize).
If aspect is greater than 1, then the ysize will be used in the aspect
ratio calculation. If the aspect is less than or equal to 1, then the
xsize will be used in the aspect ratio calculation of the final window size.
If the input to the ASPECT keyword is an image, then the aspect ratio will
be calculated from the image itself.
color: in, optional, type=string/integer, default='white'
If this keyword is a string, the name of the data color. By default, 'white'.
Color names are those used with cgColor. Otherwise, the keyword is assumed
to be a color index into the current color table. The color is not used if
the "window" is opened in PostScript on the Z-graphics buffer.
force: in, optional, type=boolean, default=0
Because of the way cgDisplay is designed to work in many devices and in resizeable
graphics windows, it is sometimes the case that it won't create a window for you.
If you set this keyword, a graphics window will be created while in any device that
supports graphics windows.
free: in, optional, type=boolean, default=0
Set this keyword to open a window with a free or unused window index number.
This keyword applied only to graphics windows created on the computer display.
location: in, optional, type=integer
Set this keyword to a two-element integer array indicated the pixel position of
the upper-left corner of the graphics window from the upper-left corner of the display.
match: in, optional, type=boolean, default=0
If this keyword is set, the new display window will match the size of the current
display window, if there is one.
pixmap: in, optional, type=boolean, default=0
Set this keyword to create a pixmap window (a window in memory only).
retain: in, optional, type=integer
Set this keyword to the values 0, 1, or 2, to indicate no backing store, server
provided backing store, or IDL provided backing store, respectively. By default,
set to 1 for Windows users and to 2 for UNIX users.
title: in, optional, type=string
Set this keyword to a string that is used as the window title.
wid: in, optional, type=integer, default=0
The window index number of the IDL graphics window to create.
window: in, optional, type=integer, default=0
Because I want to use cgDisplay everywhere, including in resizeable graphics
windows, and I don't want it opening windows then, it first checks to be sure
there are no resizeable graphics windows on the display before it creates a window.
Setting this keyword will overrule this check and create a normal IDL graphics window
on the display. This will allow you to open a normal graphics window at the same
time a resizeable graphics window exists on the display.
xpos: in, optional, type=integer
The X position of the window, specified in device coordinates. On Motif platforms,
XPOS specifies the X position of the lower left corner and is measured from the
lower left corner of the screen. On Windows platforms, XPOS specifies the X position
of the upper left corner and is measured from the upper left corner of the screen.
This value can also be specified as the first element in the `Location` keyword.
xsize: in, optional, type=integer, default=640
The X size of the graphics window created. By default, 640. The PXSIZE parameter
is used in preference to the XSIZE keyword value.
ypos: in, optional, type=integer
The Y position of the window, specified in device coordinates. On Motif platforms,
YPOS specifies the Y position of the lower left corner and is measured from the
lower left corner of the screen. On Windows platforms, YPOS specifies the Y position
of the upper left corner and is measured from the upper left corner of the screen.
This value can also be specified as the second element in the `Location` keyword.
ysize: in, optional, type=integer, default=512
The Y size of the graphics window created. By default, 512. The PYSIZE parameter
is used in preference to the YSIZE keyword value.
_extra: in, optional, type=any
Any keywords supported by the WINDOW command are allowed.
