Installing

When you unzip the PixelSense 742 zipfile, you will have a file called PixelSense742.exe, approximately 580K in size. There is no installation, support files, DLLs, registry entries or other cruft necessary. Place the PixelSense742.exe file anywhere on your system that is convenient for you. To run PixelSense 742, simply double-click the EXE. If you would like to add PixelSense 742 to your Start Menu, right click on PixelSense742.exe and select the Create ShortCut item from the popup menu. When the shortcut icon appears in the same directory as the PixelSense742.exe, drag the shortcut onto the Windows Start Menu (or QuickLaunch bar, or other locations in newer versions of Windows).

Preparing Input

PixelSense 742 is designed to process any 742 RGB GeoTIFF (or TIFF) image from any source. These images are supplied as a single file, with the Mid Infrared band stored where the Red channel normally would be, Near Infrared is stored where Green normally would be, Green is stored where Blue normally would be. There is no real Red or Blue channel supplied at all.

Images of this type are commonly available from numerous sources on the web. Sometimes they are supplied in other file formats (like MrSID) which PixelSense 742 currently cannot read. These images must be converted (and typically cropped) before being used with PixelSense 742. See the Links page for sources of 742 imagery for PixelSense 742.

If the files are supplied compressed in the GNU GZIP (.gz) format or ZIP for, Programs like WinZip and 7-Zip (free) can be used to extract the .tif files. You will need to extract the .tif files manually before running PixelSense 742.

Running

When PixelSense 742 is launched, you will be presented with the main window.

At this time, there are no user-adjustable settings for the PixelSense 742 process. Click on the Open File icon (image of a small yellow folder) in the upper right corner of the window. A File Dialog will appear to allow you to select an input file (or files). When you have selected one or more files, PixelSense 742 will begin creating the finished image.

Another short time later, PixelSense will finish its work, having created a new image in the same directory named something like 24682N.tif. The capital N appended at the end of the original name signifies that this is the Natural Color image. This image file should be approximately the same size as the input image. If the input image was compressed with one of the various TIFF compression methods, the output image will be larger because it is not compressed.

Command-line Options

PixelSense 742 can accept command-line arguments to supply one or more input filenames.

Example:

• PixelSense742.exe 24682.tif

PixelSense 742 can accept wildcards in either/both the directory and filename portion of the file specification. This can be used to process entire directories of dozens, hundreds or even thousands of TIFF files at once. Multiple wildcards can be present in each command-line argument. Both the '*' (0 or any number of characters) and '?' (any single character) are accepted. Multiple wildcard-utilizing arguments can be provided at once.

Examples:

• PixelSense742.exe C:\742\Images\*.tif
• PixelSense742.exe C:\742\Images\Colo*.tif
• PixelSense742.exe C:\742\Images\j*k*.tif
• PixelSense742.exe C:\742\Images\j*k19?.tif
• PixelSense742.exe C:\742\Images\Colo*.tif C:\Downloads\742\*.tif

The unregistered Demo version does not have any time limitations, but all output natural Color images it creates are watermarked with a checkerboard pattern in the Red channel. Every alternating square of the checkboard will have correct coloration, the squares will be brighter Red.
