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.

Catalog

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.

Framebuffer

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.

Tools

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

Views

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.
