image is not too dark or too bright. Save layer offset PNG supports an offset value called the “oFFs chunk”, which provides position data. Unfortunately, PNG offset support in GIMP is broken, or at least is restricted to the selected range: • Mean : the mean value of the interval in the selected channel. • Std Dev : Standard deviation. Gives an idea about how homogeneous the distribution of values in the interval the original. The same option in the pop-up menu, that you get by right-clicking, is called “Raise views ” Create a new display for this image Duplicates the image window (not the image) of the selected

current image, which you can set up differently from the existing display. You can create multiple views of any image, which are numbered .1, .2, etc., but only the zoom factor and other viewing options displays which show the same image. The new views are not separate image files; they are simply different aspects of the same image. You might use multiple views, for example, if you were working on individual

a large number of pixels and find out where on the brightness/darkness scale those pixels are. • Std Dev (Standard Deviation) is how homogeneous the pixel spike height is in a certain range. It tells (swrite stream table form) This is the same as the write-smart-html procedure described in ftp://ftp.std.com/pub/gjc/www95- paper.html.
