Synopsis:

printwin

printwin option=value [,option=value, ...]

Arguments:

option

An option for printing images. See table below.

value

A value associated with the matching option . See table below.

Value Meaning

Default Value

banner

banner string

This is a string to print to the top and bottom of a PostScript TM output file.

""

capture

on, off

Whether or not to get the image to save by doing a screen capture.

on

command

UNIX command

Use this field to specify a printer command, like lp or lpr . You can also modify this to add other printer options as long as the -P option remains the last on the line.

lpr -P

printer

printer name

The name of the printer to send the image to for printing.

colorps

tiled

on, off

A flag indicating whether or not to print all open graphics windows as a single image.

off

type

ps, vps

The type of the printer the image is being sent to for printing.

ps -- Raster PostScript TM
vps -- Vector PostScript TM , 2D plots only

ps

xres

positive integer

The resolution in the X direction. Only used when capture is off, and only applies to the ps format. If you specify xres , you must also specify yres , and the two numbers should be equal to each other.

yres

positive integer

The resolution in the Y direction. Only used when capture is off, and only applies to the ps format. If you specify yres , you must also specify xres , and the two numbers should be equal to each other.

Description:

The printwin command without any options prints the contents of the current visualization window to the network printer. With options, the printwin command sets parameters for future window prints, but does not actually print the window .

The ps format corresponds to a raster image imbedded in a PostScript TM file and is resolution dependent. The vps format contains lines a polygons in a PostScript TM file and is resolution independent. Images with 3D graphics cannot be rendered using the vps format. When MeshTV detects a situation where the vps format cannot properly contain the image it will automatically switch to the ps format.

Note that if the capture flag is on, the picture will be "grabbed" via a screen capture. This means that if you open another window on top of your visualization window and then issue the printwin command, you will see the second window in your printed image. The default for capture is on , because this is the quickest way to get the picture. If the capture flag is off, the picture is generated internally at 24 bits at the specified resolution.

Examples:

printwin printer=color6

printwin tiled=on, printer=mycolor
