ParaViewGeo allows several options for saving information in the program. You can choose to save individual data information, projects as a whole, and even screenshots of what is visible in the view window.
You can save individual datasets by clicking File > Save Data (or Ctrl+S). This option saves properties such as the velocity of the dataset. The file format the data can be saved in depends on the data type, which is found on the Information tab in the Object Inspector. All the possible file formats can be found in the Supported Writers list.
You will always be prompted for a file name, as ParaViewGeo is based on the rule that you never modify the original data. By prompting for a file name every time, you won't accidentally overwrite existing data on the drive. When the file name is entered and the location is chosen, click on OK. This displays the Configure Writer window where you can choose the Data Mode and Ghost Level.
The Data Mode drop-down contains three options; Appended, Binary and ASCII. When saving data with the Appended mode, the data is written in binary format after the XML metadata. The Binary mode writes the data in between the tags of the XML metadata. ASCII converts all the data into ASCII strings; this is really only useful for small data that needs to be displayed in a text editor.
The Ghost Level is only valid for parallel data sets, and will save extra layers of cells between files.
For most users, the default settings of Data Mode: Appended and Ghost Level: 0 are sufficient.
Note: When data is saved, the complexity of the data is reduced. For instance, if the dataset has a filter applied such as clip or threshold, saving will only save the results of the filter, not the original data.
Once you have modified your data or simply loaded it in ParaViewGeo, you will want to save the changes. To save a project, click File > Save State (or Ctrl+Shift+S), name it, and click OK. This will save the changes made to the datasets in the Pipeline Browser and the location of these datasets; this does not save the data itself! Therefore, the state file (*.pvsm) saves the location where you loaded the data from and the name of the files, as well as any filters that were applied and actions that were performed so the current visualization can be fully re-created.
Information on all the files loaded during the session is saved, so even if a dataset is no longer part of the pipeline, certain information is still stored in the state file. If you delete, move or rename a file referenced in a state file and then try to load that state, it will not find the dataset and an error message will appear. This error message can be closed and any other datasets referenced in the state file that are still in their original locations will load.
Additional information regarding State Files is found in the next manual section.
ParaViewGeo allows you to take a picture of what is currently rendered, which could be used to add a representation to a PowerPoint presentation, set the image as the desktop background, attach the picture in an email, etc.
To take a screenshot of what is shown in the View Manager, click File > Save Screenshot. If you want the shot that you currently see, make sure the Save only selected view option is checked. Adjust the resolution if necessary and select the image quality, then click OK. Choose a storage location, enter a name for the screenshot, select the file type, then click OK. Possible file types are *.png, *.bmp, *.tif, *.ppm, *.jpg and *.pdf.
Note: There is a known bug that prevented saving screenshots that included a spreadsheet view, which has been corrected in version 1.4.14. If there are several windows, one of which is a spreadsheet, the screenshot would omit that view and show all others. If a screenshot was the only view, an error message would display. As of version 1.4.14, all view types can be saved as screenshots.
Saving the geometry of data allows you to save all the geometries currently loaded in ParaViewGeo into a single multiblock dataset to provide the ability of rendering and viewing it in another application. This option is also found in the File menu. The only file format option that exists is to save the dataset as a ParaView Data File (*.pvd). The file will not hold on to properties such as color, but it does save the data arrays associated with the dataset.
Saving geometry can be combined with animations, as the geometry of the entire animation will be saved. The geometry will include the same number of times steps as the animation. Note that all the geometry in the view is saved, not just that of the selected source.
An animation can be saved outside of ParaViewGeo either in a movie file format, or as image files. The movie format (*.avi) can be played back in programs such as Windows Media Player, whereas the image format will create a separate image file for each step of the animation. To save an animation, select File > Save Animation. An Animation Settings Dialog window appears where the Frame Rate, Number of Frames and Resolution can be changed. Click on Save Animation, specify a file name, and select the file type in the drop-down menu before clicking OK.
Another available option is export, which allows you to export the visual scene so it can be opened by other visual engines. There are a limited number of options, as only four scene file formats are supported, the main one being *.vrml. The other supported formats are *.pov, *.x3d and *.x3db.
