    • 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.
    • 要呈现在电子设备的电子显示器上的数字图像被扩展,使得数字图像的内容符合电子显示器,并且边缘在电子显示器上被裁剪(例如,变得不可见)。 初始确定可以是数字图像的左边距和右边距的第一总长度。 第二确定可以是数字图像的顶部和底部边缘的第二总长度。 可以导出至少部分地基于第一和第二总长度中的较小者的膨胀系数。 扩展因子的应用使得能够创建具有最大地适合于电子显示器的内容的扩展数字图像。 在一些方面,扩展的数字图像被存储在数据高速缓存中。

    • An image-based document may include text that is presented in a multicolumn format that is not structured or associated with metadata of the document. A zoom manager may analyze the image-based document, identify a presence and location of a column of text, and then enable automatic zooming-in on the column of text to fill a display space without further interaction by a user. In various aspects, the zoom manager may order the columns to enable the user to continuously scroll from column to column while navigating the document in a column-viewing (zoomed-in) mode. The zoom manager may also selectively maintain or remove information or objects from the columns while in the column-viewing mode, such as images, headers, footers, page numbers, or other types of information or objects.
    • 基于图像的文档可以包括以不是结构化或与文档的元数据相关联的多列格式呈现的文本。 缩放管理器可以分析基于图像的文档,识别文本列的存在和位置,然后在文本列上启用自动缩放以填充显示空间,而无需用户进一步的交互。 在各个方面,缩放管理器可以排列列以使得用户能够在以列观看(放大)模式导航文档的同时不断地从列到列滚动。 缩放管理器还可以在诸如图像,页眉,页脚,页码或其他类型的信息或对象的列观看模式中选择性地维护或移除列中的信息或对象。
