GS-800 Imaging Densitometer
7-13
To turn on oversampling, click on the More Options button in the acquisition
window and click on the Oversample checkbox.
With oversampling on, you can specify your own resolution within the range
of the densitometer by entering values directly in the fields next to X
resolution and Y resolution in the main acquisition window.
Auto Save After Scan
To automatically save any scan you create, click on the Auto Save After Scan
checkbox.
Note: In PDQUEST, this option is preselected and cannot be turned off. All
images must be automatically saved when acquired.
With this checkbox selected, when you click on Acquire, a Save As dialog box
will open asking you to specify a file name and location for the image you are
about to create. The scan will begin when you click on the Save button.
Make Backup Copy
If you have checked Auto Save After Scan, you can also automatically create a
backup copy of any scan you create.
Click on the Make Backup Copy checkbox. With this checkbox selected, when
a scan is created and saved, a backup copy will be placed in the same
directory as the scanned image. Windows backup files will have an “.sbk”
extension. Macintosh backup files will have the word “backup” after the file
name.
This backup copy will be read-only, which means that you cannot make
changes to it. You can open it like a normal file, but you must save it under a
different file name before editing the image or performing analysis.
Highlight Saturated Pixels
When this box is checked, any saturated pixels in the image will appear
highlighted in red in the scan window and in the pop-up image window. To
view/hide saturated pixels in the pop-up image window, use the Image >
Transform command.
