Image Tool ("it") is a robust framebuffer/render view window, offering complete floating point support and a powerful and flexible catalog, as well as a fast and powerful imaging tool that is capable of production-qualilty image manipulation and compositing usually found only in high-end standalone products.
User Interface
...
The "it" window can be customized by selecting options in the first two sections on the "Window" menu These optional windows and toolbars can be shown or hidden from the menu, or toggled on or off with their associated hot key as displayed in the menu. They can also be docked into the main window or left as floating windows. Double-clicking on the title bar of one of these sub-windows will toggle it from docked to undocked. Toolbars, such as the "Pixel Readout" toolbar, don't have a title area since they are so small and instead have a grab handle at the end or top that is used to place them. The grab handle can also be double-clicked to toggle the docking.

The remap menu shows the color space that your image is in. Typically this would be linear for rendered images and sRGB for 8 bit image files. By default "it" chooses the image space of the image and when it does this the image space is preceded by a *. You can use the menu to override "it"'s choice (the * indicator will go away)
"it" supports view mapping output images to accommodate your workflow of choice using the OpenColorIO system (http://opencolorio.org). Your view mapping defaults can be set for images rendered to "it" as your framebuffer (regardless of bit depth) or for imported images (with different mapping for different types, if necessary).
There are several important things to remember about remapping:
Remapping is applied only for viewing files. It is not burned in. See Burn Mapping On Save preference.
Images rendered via RenderMan are, by default, in linear space, unless an exposure is applied to the output (which can be done in RfM via the Output Settings tab of the RenderMan controls).
If you do apply an exposure to your output, be sure to make the proper adjustment to the default image mapping for rendered images.
The OpenColorIO setup can be changed via your it.ini, though, as always, we strongly recommend making the changes in a site-specific surrogate ini file, referenced via RMS_SCRIPT_PATHS. "it" will also use the environment variable OCIO if it is set to find the OpenColorIO config file.
A special entry on the remap menu is the Shadow Map option, which is useful for viewing shadow map files. These files can have huge ranges that are well beyond zero to one, so the traditional way to display these has been to rescale the min and max values to zero and about 0.9, and then invert them with (1 - val).
