New Dialog Box

	This dialog box lets you create a new stereoscopic image from three different sources: 1- You can create a new stereoscopic image from two image files.  This is the most usual case.  See Left/Right Half Height Flag in the Image menu for information on last check box.   2- You can create a new stereoscopic image from an interlaced image file.  The left image is created by using the even scan lines (0,2,4,...) and the right image is created by using the odd scan lines (1,3,5,...).  Often the left and right images contained in an interlaced image file have only the half of the total horizontal scan lines of the stereoscopic image they represent.  In such case, after the creation of the stereoscopic image, in order to display correctly the stereoscopic image, you must select the Left/Right Half Height Flag in the Image menu.   3- You can create a new stereoscopic image from a red blue anaglyph image file.  The left image is created by using only the red component and the right image is created by using only the green and blue components.  The result is that no green or blue lights are present in the left image and no red light is present in the right image.  So if you want this stereoscopic image to be viewed in display modes other that the red blue anaglyph display mode, you must select the Convert the resulting left/right images to grayscale check box.  The only case to not select this check box is when you are creating a stereoscopic image using a pseudocolor red blue anaglyph image file, and you want to keep the pseudocolors.  But in this last case, the stereoscopic image can only be viewed correctly in the Pseudocolor Red Blue Anaglyph display mode.  See Left/Right Half Height Flag in the Image menu for information on last check box.
