Digital image cropping

摘要

A digital image to be presented on an electronic display of an electronic device is expanded so that the content of the digital image fits the electronic display and the margins are cropped (e.g., rendered invisible) on the electronic display. The initial determination may be for a first total length of a left margin and a right margin of the digital image. The second determination may be for a second total length of a top and a bottom margin of the digital image. An expansion factor based at least in part on the smaller of the first and second total lengths may be derived. The application of the expansion factor enables the creation of an expanded digital image having content that maximally fit the electronic display. In some aspects, the expanded digital image is stored in a data cache.

主权项

1. A computer implemented method, comprising:
under control of one or more computing systems configured with executable instructions, determining a first total length of a left margin and a right margin of a digital image for presentation on an electronic book (e-book) reader device; determining a second total length of a top margin and a bottom margin of the digital image; deriving an expansion factor based at least in part on a smaller length of the first and second total lengths; and applying the expansion factor to the digital image to create an expanded digital image having content that maximally fits the e-book reader device to effectively crop the margins from display on the e-book reader device.
