ICE’s main window interface is divided into three main parts:
Workspace
The Workspace view is where all layers are drawn and can be managed from.
The blue border within the Workspace view represents the Canvas region, objects placed outside of the Canvas will not appear within the output.
Workspace Navigation
Zooming - middle muse button scroll
Reset Zoom - middle mouse button press
Pan - right mouse drag
Layer List
The Layer List view displays all of the layers contained within the Workspace. The order of the layers within the Layer list view dictates which order they are drawn to the Canvas.
Layer Settings
The Layer Settings view contains all the settings for the currently selected layer. The view is split into two sections, the left section shows generic settings which are the same for all layer types, the right section shows setting specific to the selected Layer type.
