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.
