Adobe updated Ideas, its vector-based sketchbook application for the iPad, earlier this week. The 1.2 version of the iPad application is available for free and lets users grab a capacitive stylus or their finger to create a drawing or add annotations to images. This latest version adds a new premium layer functionality that lets you add up to ten drawing layers and one photo layer for each sketch. You can also change the layer order and opacity as well as rotate, move and scale each layer using this new tool, which is available as an in-app purchase.
Originally introduced in April 2010, the Ideas application lets you zoom and pan as you create so that you can focus on selected areas of your sketch. As a bonus, you can output your creations to an external VGA display using the Apple VGA adapter. Other new features include the ability to move the toolbar from the left to the right side of the drawing canvas and improved stroke smoothing.
