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.
Click and holding down the left mouse button on the framebuffer image window will allow you to pan around the image. (Default hotkey: 1)
Click and holding down the left mouse button on the framebuffer image window will allow you to zoom in and out of the image. (Default hotkey: 2)
This allows you to edit the color of the recent bucket marker. See Recent Bucket Markers.
Focus Incoming Render
If toggled on, the image window will automatically display the current incoming render.
Sets which view mapping to use when Automatic view mapping is selected from the remap menu, for different bit depths (8-bit, 16-bit, Float) and whether the image is from an incoming render or from disk.
Allows you to edit any of the hotkeys mapped to specific commands in "it".
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.
When 'it' is being used as the destination for a render it will display a rectangle around each bucket as it arrives. The indicator will fade over a few seconds. This is useful when an image in being refined as it is sometimes difficult to see what part of the image the renderer is working on. This feature can be toggled on and off and the color of the rectangle can be altered in the preference dialog.
