Input datasets may be images, optional IBIS graphics files, or lookup
table files. If no output image is specified, then the input image is modified
by the program. If an output image is given, then the input image is copied to
the output image upon execution of the program. Optional IBIS graphics files
are used by the program in 3 modes. They may 1) be displayed on the graphics
plane for reference (such as a coastal outline); 2) contain closed polygons
to be used by the program for polygonal operations (such as filling and
copying); and 3) be drawn into either the image or graphics planes of the
video memory. The same filename can be used for an input and output graphics
file (even if the file does not exist upon entering the program from the Vicar
command line). This allows the user to create polygonal graphics files from
within the program and save them to the output graphics file. Similarly,
lookup table files can be specified in the input and output command fields,
generated from within the program, and saved and restored as desired. The
lookup tables have the same format as those used by programs IDX and LOOKUP.
If the input images (color mode) are being modified, they must have different
filenames. A total of 10 input files are supported by the program.
Output datasets may be images, IBIS graphics files, or color lookup
table files. All three file types are optional.
Some possible examples are as follows:
edimage MONALISA.BW No output - input modified
edimage MONALISA.BW NEWMONA.BW Modified output image NEWMONA.BW
edimage (MONA.R,MONA.G,MONA.B,MONA.GRA,MONA.TBL) + Modified image will
(LISA.R,LISA.G,LISA.B,MONA.GRA,MONA.TBL) 'COLOR will be written to
to the LISA.* files.
Notice that the same name is given to the input and output files MONA.GRA
and MONA.TBL, allowing graphics to be generated from within the program,
saved to MONA.GRA and restored from input MONA.GRA at a later time within
the same program session. The same is true for the MONA.TBL color lookup
table file. A total of 10 output files may be specified from the command line.
The standard Vicar size field used for determining the window to copy to the output image. This parameter is ignored if there are no output images and the editing is being conducted on the input images.
The starting line in the editing window.
The starting sample in the editing window.
The number of lines in the editing window.
The number of samples in the editing window.
This is the keyword used for distinguishing between color and black and
white mode. The program has no way of determining, without the MODE keyword,
if one image and several IBIS graphics files and/or color lookup table files
have been specified or if there are three images and optional files specified.
The part of the screen unused for image display may be used as a scratch-
pad, and it sometimes occurs that one wishes to use parts of various images
displayed on the image planes from a previous use of the display processor(eg,
another session of "edimage" or perhaps IDX). By default "edimage" will clear the
image planes before the session begins(SCREEN="CLEAR").
The 'NOCLR keywork preserves whatever was on the image planes
before "edimage" was invoked; This can be used to piece together
a lot of unrelated images displayed previously with IDX, etc.
The TEST parameter enables test mode. The test mode differs from the normal mode only in that the command lines are read using TAE parameter processing, treating each command line as a single string. This allows "edimage" to be run from a TAE script file. Each command line must be enclosed in quotes if there are any embedded blanks.
