Follow the guide of each application. On Windows PC, "Fn" + "Print Screen" can capture the display.
Display your figure and execute the command
$ xwd > result.xwd
in a terminal, then click the window that you want to capture.
The image of the window you have clicked on is stored in a file "result.xwd". The output filename is an example.
Probably you want to convert the figure format into a more popular graphic format such as JPEG and PNG.
$ convert result.xwd result.png $ convert result.xwd result.jpg $ rm result.xwdThen, download the figure file to your PC so that you can display, edit and paste it in a text file.
Instead of the commands that output graphics on display, use the commands to generate a PostScript file.
$ supswigb < result.su perc=... > result.eps
$ supswigp < result.su perc=... > result.eps
$ supsimage < result.su perc=... > result.eps
The commands "supswigb", "supswigp", "supsimage" are the PostScript version of "suxwigb" and "suximage" and have similar command options to the corresponding command.
"supswigp" generates polygon data, resulting in more beautiful output than "supswigb", however, the larger the file size is.
The options to set the size, color scale, axes labels, and formats can be displayed when you execute the command without options, like
$ supsimage
$ psimage
Then you can download the file to your PC or you can print them using a PostScript printer.
Some freeware to display waveform on PCs are available.
