Files utilized by SpectraPLOT include (file extensions are shown in parentheses):
A SpectraPLOT workspace file contains parameters that allow users to save the state of SpectraPLOT application. SpectraPLOT workspace files have a ".svw" extension.
Note that the SpectraPLOT workspace file is different than a SPECT3D workspace file.
The project data are saved to the workspace file by selecting either the File | Save or File | Save As menu items. A previously-stored workspace file is opened by selecting File | Open.
The workspace file can also be used as an input argument when starting SpectraPLOT. Windows platforms can be configured to start a SpectraPLOT application when double-clicking on a file with a ".svw" extension.
Contents of the workspace file include parameters related to the plot windows and their contents. While not all aspects of a plot window edited by the user are saved, many parameters are saved so that the state of the application is to a large degree restored when starting up SpectraPLOT with a given workspace.
Images from any plot window can be save in any of the following formats: .bmp, .jpg, .png, .xbm, .xpm, .pbm, .pgm, .ppm.
To export an image, select the Files | Export Image menu item.
Images can also be exported by selecting the File | Export Image | Image menu item.
For Images in which multiple time gates are used, image files for all time gates can be generated by selecting the File | Export Image | All Gated Images menu item. (This menu item is available only when an Image plot window is set up to use multiple time gates.)
For Images in which multiple time gates are used, image data files for all time gates can be generated by selecting the File | Export Image | All Gated Data menu item. (This menu item is available only when an Image plot window is set up to use multiple time gates). A series of ascii data file will be generated. The file names are created from a string user provides in export dialog followed by three digits for gate index. Additional index file (<run_name>_index.dat) will be created to serve as a table of content. The header contains format ID's, total number of gates, gate type. For each gate, the gate index and time parameters are written. Also written is a full path to the corresponding data file.
Data files contain all image data. The header contains format ID, gate index, pixel numbers and data type ID. The data block contains x-y position for all the pixels and corresponding intensity value (as z-axis). There are three DataType ID's: 1 - for regular x-y grid in rectangular detectors; 2 - for circular detectors, x-y representation of regular r-theta grid; 3 - for radial detector, in this case the number of pixels in theta direction is always 1, and only radii are written for position (2-column table). Other data type ID's are reserved for future use.
