US Patent 9164874 Testing conversion and rendering of digital content

Some examples include testing of software able to render a content item on a display of an electronic device. The testing may include capturing images of rendered portions of a content item and comparing the captured images with previously obtained reference images that have been verified to be correctly rendered. The testing techniques can be applied to conversion software that converts digital content items from one format to another and/or testing of the converted content items themselves. Additionally, content presentation software that displays digital content items on an electronic device, such as by interacting with rendering software, may also be tested using a similar technique.
