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 quality image manipulation and compositing usually found only in high-end standalone products.


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.


For screens with a high DPI you may find the text is hard to read. You can change this manually. Look for the file here:


This acts like a Cascading Style Sheet for "it". You can alter the text size using this section:

Code Block
QLabel#PixelReadout {
    font-family: Courier;
    font-size:   20px;
    margin-left: 10;

Since we don't recommend altering shipped files, you may put a copy of your new .qss file in your custom directory defined by the environment variable: RMS_SCRIPT_PATHS



This window shows all the images and renders that are stored in the current "it" session. Multiple catalogs can be used, each storing their own images. To create a new catalog, go to File->New Catalog.
