• Profile FAQ

1. Click on the window where you want to use the profile tool.
2. Click on the Image! button.
3. Click on the 'Line on' button.
4. Select a direction for the line.  This just initializes the line at a convenient orientation for you.
5. Select a width for the line if you want to average pixel data on either side of the central line.
6. Position the line by dragging its endpoints.  Dragging by the center preserves its angle.
7. Click on 'Plot' to plot the profile. The 'Color!' button changes the color of the line on the image to the selected color - the color of the Color Menu.

1. Click on 'Cursor on'.
2. Drag it with the mouse.
3. On Plot options
   1. Off:  Cursor mark on the plot does not move, and does not even appear if it has not been used.
   2. After move:  Cursor mark moves on the plot to match the location on the line in the image, after mouse up.
   3. Real time:  Cursor mark on plot follows cursor on line in image.

1. Use 'profiles -> Print profile'
2. Cut and paste to Excel or text editor, and save.

Buttons

• Image!      Click to select the image on which to show the profile line tool.
• Line On!    Activates line profile tool.  Shows the tool.
• Line Off!   Hides the line profile tool.
• Reset!      Repositions tool to middle of window.  Handy if the image has been scrolled.
• Color!      Sets color of tool to the color of '***Buttons*** / Pick Color'
• Width       Sets width of profile line.  Values are averaged across the line. You select the radius, ie. total width = 1 + 2*radius.
• Cursor On!  Shows movable cursor.  For measuring along the line or marking specific
•             locations on the image and on the profile plot.
• On plot     How to track the cursor position on the plot.
• Profiles
•       Print Profile     Prints out position information of the line profile tool, and
•                         the profile data, much as 'Other Plots / Print' does.
•       Plot Sigma        Plots standard deviation along profile line, for line
•                         widths of 3 or more.
•       Profile to image  Makes a plot that is 'burnt into' an image.
•       Reset serial counter    Plots have a serial number appended to their name.
•                               The number defaults to Pa01, for example.
•                               'P' stands for plot, the 'a' can be changed.
•                               You can change the name of the plot manually with
•                               '***Buttons*** / Rename!'
•       20% - 80% Width   A special purpose measurement tool that hasn't been tested much.
• Plot!       Actually plots the pixel data along the profile line.
• Group!      For selecting a group of images rather than just one.  Overrides 'Image!'
• X!          Clears the group selection.

• Other Plots  

    

• Vertical Sum      Plots sum for each pixel collumn of front image.
• Vertical Max      Plots max for each pixel collumn of front image. (New with Lx41).
• Vertical Variation  Plots variation (absolute value of differences) for each pixel collumn of front image.
• Vertical Variance  Plots variance for each pixel collumn of front image.
• Unwrapped   Plots pixel values for entire image in scan order.  For use on small images.
• Smooth      Convolves a plot using the kernels from Savitzky & Goulay,  Anal Chem 36:1628, 1964.  Spectrum smoothing and derivatives, with moving interval fit.
• Print       Moved to Plots menu in Lispix menu bar.
•  Ring Average  Ring average and sector average plots are now in the Analysis button of the Circle Tool.
