[input_file_name]
When the cursor crosses or enters a image window, this image will become active and its name is displayed onto the File Control Button message line and all panel setting change to this image. There is no clicking needed to make a window active. When many image windows are opened by tuner on a screen, iconifying may be necessary. Press F3 key on an image window or click on up-left corner of an image window to iconify that image. Same operation on icon will deiconify the image.
Important note:
Crossing the icon with the cursor will not activate its image window
since the icon is not an activable window. So, use the icon to keep images
inactive when many images are open.
When the cursor is in an image window (not an icon window), click button 3 and drag mouse to crop a subimage which is a solid rectangle. As long as the rectangle is on an image window, any operation on that window only applies to the subimage. So, this is a way to save a subimage (which may be enhanced). To uncrop the subimage window, simply click this button once in that image window.
The following 3 actions are depended on compiling mode.
(EXTENDED_COLOR-True_Color)
SHIFT-Button-1: Magnify
SHIFT-Button-2: Recenter magnified image at cursor pixel position.
SHIFT-Button-3: Unmagnify
2. File button: This is used to load an image file in order to analyze, enhance and save it. Whenever either the load or save button is clicked by mouse button 1, the system beeps and gives a message on the information line to tell you how to input the file name. The pressed file button will light up and the input area is at the right side of the file control button. If there is an old file name in the input area, you can modify it by using backspace key to erase or the Tab key to continue to add more characters. Any other key will erase the old file name and start to input of a new file name.
If no more space is left, see replacement rule in option [-images #].
3. Frame/Channel Control button: This button lets the user see the next frame or go back previous one. The current frame number is displayed on leftmost button in the button set. The Frame(second) button let you quickly jump to a special frame in the image. When right mouse button clicked on those button, the movie will start. In color version - getx, it controls RGB channels. SYNC adjusts 3 channels in same time.
4. Histogram Control button:
The GRID and NEG buttons can add a grid to the histogram image or negate the
histogram image whenever a colormap change is needed.
Set and Scale buttons:
Set - this sets linear scaling and histogram scaling to a fixed value. Every
frame will use these same values. Scale - uses log2 scale for histogram window,
but linear scale will be changed along with min & max values in each frame.
Scale sets the linear scale for each frame and uses the histogram enlarge scale
factor with their own histogram maximum count, minimum and maximum gray level
values across frames for analysis.
5. HistoEq press button: This button sets enhance mode for histogram equalization. If the ETA mode was in linear mode, the HistoEq button will keep lighting up and histogram equalization mode is maintained. It can be reset to ETA mode by pressing the refresh button, or ETA is changed to other mode.
6. Emphasis Control button: This is the main enhancement control button. It controls sliders above it. fore (emphasize foreground) and back (emphasize background) invoke the elastic histogram stetching algorithm. linear is linear scaling. The elastic algorithm will use the lower and higher threshold which are set by linear scaling. For different frames, these thresholds can be fixed (set to a certain position) or variable (depend on min & max in that frame).
7. Zero On-Off button: It controls whether or not to count zero's value for enhancement.
8. RESET press button: It sets every thing to original state, but ETA control mode.
9. Refresh press button: This button usually just refeshs the image, but it will clear histoeq mode to EAT mode.
10. Quantizing button(14) / Fixed Panel Color button:
This is used for tuner running with other color application windows which seize
most color-map entrences. It will not change real data set but improve screen
display.
In COLOR version `getx', this button is the Fixed Panel Color control button.
When ON, the panel color map is associated with current display image window.
When OFF, the panel color map is pointed to the latest active image window.
This function can fix colors on the control panel since the panel has no its
own colors.
11. DATA button: This button is always reset to Analysis (no update). The updating is done when the DATA button is pressed. No updating occurs when you are doing any adjustments. For color images, updating only applies to the sub-image, but is applied to the entire image whenever saving image to a file.
12. Clip slider: Left control bar is to set how many top gray level values need to be clipped down. For example, 6 means to clip 255 - 249 to the value which set by right control bar. Right sliding bar sets where the top values are clipped to. If left bar=0 or right bar=255, no clipping is done.
13. Main Slider: There are a set of sliders at same line and only one shows up according to which ETA control button is clicked. They are used to adjust different curves.
14. Quantization slider: It is used when there are too few graylevels. It functions when Quantizing button is on (10).
cut
cut the sub-image (cropped) from destination window, and save it to editing
buffer. In color version, only 8-bit images can be cut. For 24-bit images,
it's same as copy command (not cut).
copy
copy the sub-image to editing buffer for pasting.
crop
do cropping in a super-size image in which the mouse cannt do it.
draw
draw line, rectangle, and arc in an image. For buttons, see paint.
paste
paste a sub-image in editing buffer to a destination window.
paint
paint an image. A menu comes for set-up color and pencil thickness, then
a message window tells how to paint, change colors, and quit from painting.
Press the left button to paint (to type in annotate, and to draw in draw mode).
Press the middle button to change features:
colors; (fonts for typing; shapes & line thicknesses for drawing.)
Press the right button to quit from editing.
annotate
Annotate an image with text. Using middle button to change color and fonts.
CTRL-Y to finish typing, or ESC to abort typing.
NOP
NO OPERATION

Interpolation Level
The default is 2. The maximum is 8. For detail, see elastic(1).
