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.
