Abstract

The problem with current interface strategies is the need to rotate images in a set of three discrete operations: 90 degree rotation clockwise 90 degree rotation counterclockwise 180 degree rotation clockwise, often performed as two 90 degree rotations This process requires the user to scan the images for each of the above situations and perform each operation separately. The proposed invention is designed to address the needs of users who have to manage large quantities of photos or other types of images. It provides an easy means to rotate a large set of images by using edge handles to identify an edge to be aligned in a common orientation. The proposed invention handles all three operations of current interfaces in one single operation thus streamlining the entire process of image rotation.

An Improved User Interface for Rotating Graphics Images

Most applications that manipulate graphics images or photos provide a variety of ways to allow the user to rotate images. Typically thumbnail views are provided along with rotate buttons that allow the user to rotate either clockwise or counterclockwise in increment of 90 degree for a given set of images.

Other types of user interfaces exist that provide the ability to rotate an image in an arbitrary direction and/or by an amount. But these user interface elements are designed to operate only on a single image at a time. This class of user interfaces is not the focus of this invention.

This invention proposes an alternative to the previously described image rotation methodology that is more natural and which can address all three previously described operations in a single pass. The proposed method is based on identifying an edge, say the "top" edge of all images that need to be rotated. The use of some type of "handle" can be used to indicate the selected edge and once all the edges have been identified they are aligned to be consistent. A sample scenario follows which should help understand this process better.

The following set of images has several which need to be rotated, some clockwise, some counterclockwise and some upside down. These have been identified with a red outline.
