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.


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.


This window shows the current image or render selected from the catalog.


This window shows information related to the selected image or render. The large text area is the Notes field. This allows you to add any meta data to the image. The Custom View option is explained later in the Views section, under Special "it" Features section.


The tools section gives you access to the most commonly used tools in "it". From left-to-right, they are:


Click and holding down the left mouse button on the framebuffer will allow you to zoom in and out of the image. (Default hotkey: 2)


Crop Tool

Allows you to draw a crop window over your image. This allow you to re-render a portion of your image. To remove the crop window, left click within the crop window and click on the X in the top right corner. (Default hotkey: 3) 


Scrub Tool

Allows you to quickly scrub through all your images in your catalog. Click and holding down the left mouse button while moving the mouse to the left will scrub backwards in the catalog; moving right will scrub forward. (Default hotkey: 5)



Select Object Tool

Will select the object in your content creation application (may not work in all bridge products). (Default hotkey: 6)


Select Surface Tool

Will select the shader for the object in your content creation application (may not work in all bridge products). (Default hotkey: 7)

Reset Zoom


Resets any zoom applied while using the Zoom Tool. (Default hotkey: X)


Wipe Tool

Allows you to wipe between two images in your catalog. (Default hotkey: 4) To use, select the first image in the catalog, then go to Image->Toggle Background. Then, select the second image in the catalog, and with the Wipe Tool turned on, left mouse button click and drag in the framebuffer window.


Toggles the current image as a background.

Wipe Direction

Changes the direction of the wipe tool (vertical or horizontal)

Cancel Render

Sequence Controls

The sequence controls sections gives you access to controls on image sequence playback. From the left-to-right, they are:


Step back one frame in the sequence. (Default hotkey: Left) 


Play Sequence

Play/pause playback of the sequence. (Default hotkey: Space)


Step Forward Frame

Step forward one frame in the sequence. (Default hotkey: Right)

Loop Mode

For further explanation of Sequences, see the Special "it" Features section.

Monitor Controls

The monitor controls gives you access to settings such as Gamma and Exposure. The right-most button resets the Gamma and Exposure controls to their defaults. There are also some useful monitor control hotkeys, including:


Gamma Down 0.1 (Default hotkey: Ctrl/Cmd + { )

Pixel Readout

The Pixel Readout window gives you control of the channels displayed, pixel remapping, as well as information regarding the current pixel that is under the mouse cursor, including pixel coordinates and pixel values. You can lock the current pixel readout by going to View->Lock Pixel Readout (Default hotkey: M).



Right-clicking in the image area of the window also provides access to the menus. Other windows that are accessible on the "Window" menu such as the "Console", which provides python scripting access to "it" are not dockable and appear as top level windows. 

Special "it" Features



Views in "it" are a combination of zooms, pans, pixel aspect ratio and view mappings. By default all images in a catalog share a view. This is convenient when you want to step through a shot that you've rendered to "it" (hot key PageUp/PageDown). When you zoom in and step to the next frame in the shot the zoom and pan remain the same. However, sometimes you'd like to be zoomed way in on one image to look at some feature and then flip between that and a zoomed out image. "it" accommodates this with Custom View. When you turn on Custom View for an image, that image then has its own zoom and pan, independent of the other images in a Catalog. Custom Views are saved if/when the Session (or Catalog) is saved.

Pixel aspect ratio is useful when working on projects that generate non-square imagery. One example of this is the film format Cinemascope. In some pipelines you might decide to keep your digital files in a format where a pixel is half the size in the horizontal direction than the vertical. 'it' allows you to specify this in the view so that on your monitor images look normal. This menu is fully configurable from your it.ini file including the names on the menu and the aspect ratio of the pixels. You may also attach short cut keys to different aspect ratios even if you customize this menu.
