CONFIGURATION (Page One of Two)



When ImprocRAD starts, it reads its configuration values from the file 

Configuration.txt.  These values are as follows:



Default Directories:  the directories that ImprocRAD will read from and write 

to if no further details are specified.  You may enter text in the edit boxes 

to change the defaults.  The 'Update Directories' button must be pressed to 

realize the entered changes. They will be reset to the last-saved values on 

leaving ImprocRAD unless you save the changed configuration.  As as alternative

to entering text in the edit control you may browse the computer for the read and

write default directories.  If you use the browse alternative there is no need to

subsequently press the 'Update Directories' button.



Button Bar Location:  Places the user-interface button bar at any of the 

four edges of the screen. The dialog boxes will appear at the left or the 

right edge of the screen depending on your choice of Button Bar location.



Image Justification:  There are nine possible image justifications, 

positions within the image display area where the image will be positioned 

if the image is smaller than the display area, these justifications are

signified by two letter combinations.  The first letter corresponds to the

vertical justification and the second letter corresponds to the horizontal

justification. Specifically: TL = Top Left, TC = Top Center, TR = Top Right,

CL = Center Left, CC = Center Center, CC = Center Right BL = Bottom Left,

BC = Bottom Center, BR = Bottom Right.



Actions on Read: When  CopyOnRead is checked, the 'Original Image' array

which the image file is read into, is immediately copied into the 'Processed

Image' array.  It is   sometimes desirable to disable this copying, especially

in cases where the 'Processed Image' array may be used for other purposes.

When the CropOnRead box is checked, a dialog box appears which allows 

cropping the image being read.  This function useful when small sections of 

large images are to processed.  It circumvents reading in the whole image, and 

then discarding a major portion.  The model is of a virtual cropping window 

centered over the input image of full dimensions. Further details on the

CropOnRead diaog box may be found under the help button for READ. Checking the

AutoRange box causes the image to be gray-level stretched on read. A histogram

is formed and the outlying 10% is clipped before stretching.  This box should

not be checked when quantitative measuremts are being done.



Actions on Read:  The method for determining the format of a file being read is

set by using a group of radio buttons. The three methods used are manual,

extension sense, and auto-sense. Manual:  When this button is selected, a dialog

box appears at the beginning of the file-reading process.  This box has buttons

labeled with the various formats that ImprocRAD can read. The user selects the

format.  Extension Sense:  When this button is checked, ImprocRAD determines the 

format of the image being read from the file extension, e.g., a file named 

test.bmp will be read as a Microsoft Bitmap (BMP)formatted image. Autosense:

When this button is checked, ImprocRAD attempts to determine the format of the

file from the structure of its header should one be present. If no header is

identified, the manual-selection dialog box is opened.
