This tool will take any image (color or black and white) and stretch the image in order to make the overall or parts of the picture brighter. The user can do this in different ways. The user can choose to brighten the whole image, a part of the image, or the white on the image.

Using the Stretch Tool

Inputs

The inputs page allows the user to select the appropriate viewer and the ROI (For example if the user has more than one viewer being worked with, they need to select which one to put the tool into, otherwise the tool chooses).
The ROI allows the user to select a piece of the image that they want to change, if the user wants to change the entire image delete the ROI by right-clicking on it and selecting "clear".
The drop down menu will select the appropriate item from its list.
It will apply the changes directly into whatever image is in the CIF Viewer.

Parameters

  y = mx + c   (where m=gain/scale, c=offset)
 
  y = abs(y)?


Offset: this allows the user to lighten the picture
Scale: this is the gain, it allows the user to lighten the white in the image
Copy: allows the user to copy the original image so that all the changes will not be on the original image. This does not mean that it makes a copy of the image that you have been working on, just the original saved image.  __footer__
