    摘要: Methods and systems for cropping images of book pages are disclosed according to one embodiment of the invention. A method may include identifying reference images and receiving cropping rectangles for the reference images. These cropping rectangles associated with reference images may then be used to generate cropping rectangles for images of book pages between the reference images. The cropping rectangles may be generated based on a linear interpolation of the cropping rectangles associated with the reference images and the number of pages between images. The method may also display one or more images of book pages with the associated one or more cropping rectangles superimposed thereon. A user may then have the opportunity to make adjustments to the position and/or size of the cropping rectangles.

    摘要: An image editing user interface includes a first control adapted to alter an image property of an image in response to a user input and a second control adapted to operate in cooperation with the first control to alter the image property in response to a user input. The image property is brightness and the first control alters brightness over a range of image values between two endpoints and the second control defines at least one of the endpoints.

    摘要: A method and system for reducing or eliminating artifacts that may occur during color reduction of images. A bias is added to a data structure that is arranged to store counts of pixel colors of an image. Counts of pixel colors of the image are added to the data structure. Via the data structure, colors from the image are grouped into buckets until the number of buckets is less than or equal to a number of colors in a palette. Then, colors of pixels in the image are mapped to colors in the palette.

    摘要: A method and system implemented in an application programming interface (API) and an object model allows program code developers to interface in a consistent manner with a scene graph data structure to output graphics. Via the interfaces, program code writes drawing primitives such as geometry data, image data, animation data and other data to visuals that represent a drawing surface, including validation visual objects, drawing visual objects and surface visual objects. The code can also specify transform, clipping and opacity properties on visuals, and add child visuals to other visuals to build up a hierarchical scene graph. A visual manager traverses the scene graph to provide rich graphics data to lower-level graphics components.
