supplied. This command opens a standard Windows file-open dialog so you can select the filename. The file is then read and a spectrum file is written to the specified directory. Gamma-
Vision attempts to read this file (in
.CHN
or
.SPC
format) and displays the spectrum. If the
Import program does not generate a file that GammaVision can read, no spectrum is displayed.
5.1.6. Print
The Print function does one of the following:
! If the marker is in an ROI, the data contents of the ROI channels are printed.
! If the marker is not in an ROI, the contents of channels in the expanded view are printed.
A standard file-print dialog opens, allowing you to print the output or save it in a disk file (mark the Print to file box). The data are formatted at seven channels per line with the channel number on the left.
5.1.7. Compare...
This function allows you to compare the currently displayed spectrum with an existing spectrum file. When the file-recall dialog opens, select the desired spectrum file. Both spectra will be displayed together as illustrated in Fig. 69, and the title bar will list both spectrum filenames.
The Compare spectrum is offset from the starting spectrum, and can be moved up and down incrementally with the <Shift +
8> and <Shift + 9> accelerators. In addition, the vertical scale of both spectra can be simultaneously changed with <
8> and <9>. Note that the Compare spectrum’s ROIs (if any were saved with the file) are not marked in this mode.
Figure 70 portrays a zoomed-in portion of two comparison files. In this illustration, the starting spectrum is displayed in color (1), the Compare spectrum is shown in color (2), the starting spectrum’s ROIs are marked in color (3), and the portion of the starting spectrum that exceeds the Compare spectrum is indicated by color (4). These colors — called Foreground, Compare,
ROI, and Composite, respectively — are chosen on the Color Preferences dialog discussed in
Section 5.9.11.2.
Press <Esc> to leave Compare mode.
