Chapter 18: External Graphics mottling and pallet limitations found on other formats, while still retaining excellent compression performance. ANSYS creates PNG files with the assistance of the following LIBPNG and ZLIB packages: LIBPNG version 1.0.5 - October 1999 Copyright 1995, 1996, Guy Eric Schalnat, Group 42, Inc. Copyright 1996, 1997 Andreas Dilger Copyright 1998, 1999 Glenn Randers-Pehrson ZLIB Version 1.1.3 Copyright 1995 - 1998 Jean Loup Gailly and Mark Adler. You can also create exportable graphics by selecting Utility Menu> PlotCtrls> Redirect Plots. In addition to the page layout and configuration options found in the Graphics Hard Copy dialog box, this method provides additional position, resolution and scaling options. When you use this option, the output functions for most of these formats are controlled from within ANSYS, instead of by the operating system. This selection also provides HPGL (plotter) and VRML 3-D rendering output, along with screen dump and animation options. Note The Redirect Plots export defaults to raster mode, even if vector is the prescribed /DEVICE mode. Ensure that the checkbox in the dialog box is checked for the desired output. You can also export Windows Metafiles directly from ANSYS (Windows systems only) by selecting Utility Menu> PlotCtrls> Write Metafile. The subsequent dialog boxes provide limited page layout and configuration options. Because most of the export methods listed above use the system's video output to generate the file format, they will not work unless you are in interactive mode. If you are not in interactive mode, and you want to export any of the above graphics types, use the /SHOW command. This method allows you to generate output files when you run your analysis from a batch file. The Courier and Helvetica font files used for text output within the JPEG, PNG and TIFF batch outputs are not accessed from your operating system. Permission to use these files is granted by Adobe Systems, Inc. and Digital Equipment Corp. in association with these functions only. 18.1.3. Printing Graphics in UNIX You can print to a post script printer from within ANSYS. Selecting Utility Menu> PlotCtrls> Hard Copy displays the PS Hard Copy dialog box. Print options, including page layout, reverse video and grey scale are available from this dialog box. The Reverse Video option affects only the background of the display. The black background provided in the ANSYS graphics window is often unsuitable for printing. Selecting Reverse Video will present the graphics on a white background. Contour colors and other colors selected from the ANSYS palette are unaffected by this option. 276 Release 13.0 - © SAS IP, Inc.

18.1.4. Exporting Graphics in UNIX The PS Hard Copy dialog box (Utility Menu> PlotCtrls> Hard Copy) also provides a number of file export formats (EPS, TIFF and JPEG) along with limited page layout options. These files can be used in various word processing and desktop publishing applications. As in Windows, you must use the /SHOW command in order to generate file exports during batch runs. To obtain additional export formats, choose Utility Menu> PlotCtrls> Redirect Plots. You can select from GRPH, PSCR, HPGL, HPGL2, JPEG, TIFF and VRML. These formats are suitable for a wide range of applications outside of the ANSYS program. Of special interest is the .GRPH file, a neutral graphics file that uses the ANSYS plotting instructions to recreate the file in applications other than ANSYS. Note The Redirect Plots export defaults to raster mode, even if vector is the prescribed /DEVICE mode. Ensure that the checkbox in the dialog box is checked for the desired output. 18.2. Creating a Neutral Graphics File You can generate a neutral graphics file (*.GRPH) and use the stand-alone DISPLAY program to view static or animated screen images, or to convert your file into the appropriate format for printing, plotting, or exporting to word processing or desktop publishing programs. The neutral graphics file is a ASCII text file containing the instructions required to produce a graphics display. You can view the displays stored on this file, using the DISPLAY program and the appropriate 2-D graphics driver, on any supported hardware platform. The neutral graphics file is not a bitmap format but an ASCII text format, which means the resolution of a display produced by the DISPLAY program usually will be better than that produced using the Utility Menu> PlotCtrls> Hard Copy. To route your graphics displays to a neutral graphics file having any valid filename, use one of the choices shown below. (In batch mode, by default, the ANSYS program assigns this filename to Jobname.GRPH) Command(s): /SHOW GUI: Utility Menu> PlotCtrls> Device Options Utility Menu> PlotCtrls> Redirect Plots> To GRPH File Utility Menu> PlotCtrls> Redirect Plots> To Screen 18.3. Using the DISPLAY Program to View and Translate Neutral Graphics Files Each subsequent graphics action command that you issue writes a separate display to this file. (Thus, a neutral graphics file can contain more than one display, with each display being sequentially numbered, beginning with 1.) You can use the ANSYS animation macros, which automatically generate a series of graphics action commands for animation purposes, to create multiple displays on your neutral graphics file. If you wish, you can reissue the /SHOW command with a graphics device name to direct subsequent displays to your terminal screen. This way, you can toggle back and forth between the screen and a file (which is appended, not overwritten) as many times as you wish. 18.3. Using the DISPLAY Program to View and Translate Neutral Graphics Files After you have created a neutral graphics file, you can use the stand-alone DISPLAY program to view static or animated screen images, or to translate your file into the appropriate format for printing, plotting, or Release 13.0 - © SAS IP, Inc.
