Menus

 The menus are File, View, Motion, Cursor and Help.

The Help menu includes one enabled item, About..., which pops up a dialogue box with version information.

The File menu includes four items.

Press Log Pixels to begin logging pixel coordinates and values. Each time a mouse button is pressed, the corresponding pixel's coordinates and grey value are added as a line to the log; the RGB of the pixel is added on the same line if the pixel is colored.

• To clear the log, press Clear.

• To save the log, press Save, and the log will be written to the named file.

• To close the log, press Close; the content of the log is retained.

Press Stretch GS to adjust the pixel values of one or all of the images.

• The ``Original grayscale range'' is the minimum:maximum grayscale values of the original image which is currently diaplayed.

• The values in ``Stretch from range'' field describe the range of values which has been stretched to 0:255 (Initially or after the image has been reset, this is 0:255.) This value may be altered to ``stretch'' the pixel values from an entered range glb:lub to the range 0:255. The formula used to recompute pixel values, given glb:lub is:

  $newValue = clip((255\times(originalValue - glb))/(lub - glb))$

  where clip(x) is: 0 if x<0; 255 if x>255; x otherwise. The only restriction is that glb < ulb . The default for glb:lub is the original range.

• The gamma may be modified simultaneously to adjust the brightness by entering a value in the ``Gamma:'' field. The value should be a positive real number. The default is 1.0.

• To modify all of the images, select the ``All'' checkbox.

• To apply the adjustments to the image(s), press ``Stretch''.

• To reset the image(s) to their original appearance, press ``Reset''.

• Close the dialog by pressing ``Close''.

Press Save to save one or all of the (modified) images.

• Browse to the appropriate directory, and enter the file name in the ``Selection'' field. To save all of the images, include an asterisk (*) in the file name. The asterisk is replaced by each image's index within the entire image sequence in the name of the corresponding file.

• The file suffix determines the format in which the file(s) are written².

• You may modify the file path manually.

• To view a restricted set of files in a directory, modify the asterisk in the ``Filter'' field and press ``Filter''.

• To save the image(s), press ``OK''.

Press Quit to terminate the application.

The View menu has three orthogonal toggled items.

When Marked is set, the subsequence consisting of all marked images is displayed.

 When Cursor is set, the cursor information is displayed dynamically while the sequence is not Animated.

 When Crosshairs is set, crosshairs spanning the entire image are displayed; the lines cross at the pixel pointed to by the cursor.

The Motion menu items start Animation of the sequence.

Run Forward sets the direction of image sequence to forward and starts animation; animation terminates at the last (marked) image of the (sub)sequence.

Run Backward sets the direction of image sequence to backward and starts animation; animation terminates at the first (marked) image of the (sub)sequence.

Auto Repeat starts animation and repeats the (sub)sequence from its first/last (marked) image, depending on the direction of motion.

Palindrome starts animation and reverses direction each time the first/last (marked) image of the (sub)sequence is displayed.

Both Auto Repeat and Palindrome pause at the first/last (marked) image of the (sub)sequence, as determined by the option:

-delay $<milliseconds\ between\ images>$x $<pause\ after\ (sub)sequence>$

(see the animate manual pages).

The Cursor menu items may be used to select the color of the Cursor and of the Crosshairs.
