To set hardcopy parameters and save hardcopy files, use the Graphics Hardcopy panel.
The procedure for saving a hardcopy file is as follows:
If you are not ready to save a hardcopy but want to save the current hardcopy settings, click the Apply button instead of the Save... button. The applied settings become the defaults for subsequent hardcopies.
Choosing the Hardcopy File Format
To choose the hardcopy file format, select one of the following items in the Format list:
| Non-geometric entities such as text, titles, color bars, and orientation axis are not exported. In addition, most display or visibility characteristics set in
FLUENT, such as lighting, shading method, transparency, face and edge visibility, outer face culling, and hidden line removal, are not explicitly exported but are controlled by the software used to view the VRML file.
Choosing the File Type
When you save an EPS (Encapsulated PostScript) or PostScript file, choose one of the following under File Type:
| For the quickest print time, you can save vector files for simple 2D displays and raster files for complicated scenes.
Specifying the Color Mode
For all formats except the window dump, specify the type of Coloring you want to use for the hardcopy file.
Most monochrome PostScript devices render Color images in shades of gray, but to ensure that the color ramp is rendered as a linearly-increasing gray ramp, you should select Gray Scale.
Defining the Resolution
For raster hardcopy files, you can control the resolution of the hardcopy image by specifying the size (in pixels). Set the desired Width and Height under Resolution. If the Width and Height are both zero, the hardcopy is generated at the same resolution as the active graphics window. To check the size of the active window in pixels, click Info in the Display Options panel.
For PostScript and EPS files, specify the resolution in dots per inch ( DPI) instead of setting the width and height.
For all hardcopy formats except the window dump, you can control two additional settings under Options:
Hardcopy Options for PostScript Files
FLUENT provides options that allow you to save PostScript files that can be printed more quickly. The following options is found in the display/set/hard-copy/driver/ post-format text menu:
Window Dumps (UNIX Systems Only)
If you select the Window Dump format, the program uses the specified Window Dump Command to save the hardcopy file. For example, if you want to use xwd to capture a window, set the Window Dump Command to
xwd -id %w >
When the dump occurs, FLUENT automatically interprets %w to be the ID number of the active window.
When you click the Save... button, the Select File dialog box appears. Enter the filename for the output from the window dump (e.g., myfile.xwd).
If you are planning to make an animation, save the window dumps into numbered files, using the %n variable. To do this, use the Window Dump Command ( xwd -id %w), but for the filename in the Select File dialog box enter myfile%n.xwd. Each time a new window dump is created, the value of %n increases by one. So there is no need to tack numbers onto the hardcopy filenames manually.
To use the ImageMagick animate program, saving the files in MIFF format (the native ImageMagick format) is more efficient. In such cases, use the ImageMagick tool import. Set the default Window Dump Command enter
import -window %w
Click Save... to invoke the Select File dialog box. Specify the output format to be MIFF by using the .miff suffix at the end of filename.
The window dump feature is both, system and graphics-driver specific. Thus the commands available for dumping windows depends on the particular configuration.
When saving window dumps is that the window dump captures the window exactly as it is displayed, including resolution, colors, transparency, etc. For this reason, all of the inputs that control these characteristics are disabled in the Graphics Hardcopy panel when you enable the Window Dump format. If you are using an 8-bit graphics display, use one of the built-in raster drivers (e.g., TIFF) to generate higher-quality 24-bit color output rather than dumping the 8-bit window.
Previewing the Hardcopy Image
Before saving a hardcopy file, you have the option of previewing what the saved image looks like. Click Preview to apply the current settings to the active graphics window. Now, you can investigate the effects of different options interactively before saving the final, approved hardcopy.
