When the file is over run with the command,<\/p>\n<\/div>\n

Then will come by the view as follows,<\/p>\n<\/div>\n

<\/div>\n
\n

From Figure 1, to take the contur generated, icon “save” can be click\u00a0 so that title would look as follows,<\/p>\n<\/div>\n

\"\"<\/a><\/div>\n

Figure 2. Save the picture in the format of the image (e.g., *. png).<\/p>\n

\n
<\/div>\n
\n
\n
\n

Enter the name of the file and the desired image format (in this example is used *. png) then press “save”. The image file will be generated, such as the following example,<\/p>\n<\/div>\n

\"\"<\/a>Figure 3. An example contour image is generated by the python script.<\/p>\n

\n
\n
\n
\n

Figure 3 is a picture generated from a python script file with the name “baca_2d. py” run like the procedure above. Where this script reads the data file in ASCII format with the name “scen-7.pma”.\u00a0The File is read and resulting the Figure 1. From the Figure 1 the image file can be saved with the name, and the\u00a0contour\u00a0format as desired.<\/p>\n<\/div>\n

So, hopefully this is helpful to all users of linux or windows that use Python as a free program (free softwares). This example File can be downloaded from here<\/a> (101,2 Kb).<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
