PROGRAM NAME

editimage - Interactive Image Display and Manipulation

DESCRIPTION

Editimage is an interactive image display and manipulation tool. The features provided by editimage include:
\(bu Transparent support of a variety of input files
\(bu Use of clip masks
\(bu Capture of images from the screen
\(bu An input file history list
\(bu For multiband images, control over which band is displayed
\(bu Normalization of colormaps
\(bu Control over which columns of the map data are displayed as red, green, and blue
\(bu Application of functions to the map data values to produce new colormaps
\(bu Interactive editing of the image file comment
\(bu Application of autocolor procedures and colormap operations
\(bu Regular and irregular region of interest extraction
\(bu Creation of new data sets as defined by an interactively specified function
\(bu Zooming on the displayed image
\(bu Display of pixel values surrounding the location of the pointer in the image
\(bu Display of map data values surrounding the location of the pointer in the image
\(bu Colormap manipulation via a pseudo-coloring mechanism
\(bu Pixel clipping and pixel thresholding on the image

The master form of editimage displays the input image in a workspace. Above the workspace are "License", "Help", and "Quit" buttons, from which one may access the license agreement, display online help pages, and quit the program, respectively. To the left of the image workspace are two subform buttons labeled "Files" and "Options".

Use the "Files" subform button to display the "Input and Output Files" subform. From this subform, you may input and output files.

A number of features are available from the "Options" subform, which contains seven panes: "Capture", "Image List", "Display", "Comment", "Colormaps", "Extract ROI", and "Function".

Beneath the "Options" subform button are five more subform buttons, each of which will display the relevant subform.

The "Zoom" subform lets you zoom in on the image.

The "Pixel Values" subform prints pixel values as the pointer is moved across the image.

The "Map Values" subform prints map data values as the pointer is moved across the image.

The "Pseudo Color" subform allows you to interactively modify the colormap of the image.

The "Threshold" subform supports pixel clipping and thresholding on the image.
