Method and system to modify source content to fit into a target display area in a browser

摘要

A method and system to automatically adjust content being layed out into a target area for browser rendering is provided. An example method comprises a first pass module, a progress data collector, a second pass module, and a communications module. The first pass module may be configured to perform a first pass of laying out source content into a total target area to determine a total crash area consumed by the source content. The progress data collector may be configured to collect progress data associated with the laying out of the source content into the total target area. The second pass module may be configured to perform a second pass of laying out of the source content into the total target area to generate a data object model. The communications module may be configured to provide the data object model to a browser engine for rendering.

1. A method comprising:
performing, using a computer, a first pass of laying out source content into a total target area to determine a total crash area consumed by the source content, the first pass comprising collecting progress data; and performing a second pass of laying out a plurality of segments of the source content into the total target area to generate a data object model, the second pass performed after the first pass has been performed, wherein the second pass comprises at least: for a first segment of the plurality of segments corresponding with a first content position in the source content:
collecting current progress data for the first segment of the plurality of segments,determining a first remaining target area value using the current progress data for the first segment, the first remaining target area value indicating a first portion of the total target area remaining to be consumed at the first content position during the second pass,determining a first remaining crash area value based on the progress data, the first remaining crash area value indicating a first portion of the total crash area that remained to be consumed at the first content position during the first pass,calculating a first adjustment factor for the segment of the source content as a function of the first remaining target area value and the first remaining crash area value,based on the adjustment factor, modifying the segment to produce a modified segment, andappending the first modified segment to a first content portion already laid out in the total target area; and for a second segment of the plurality of segments corresponding with a second content position in the source content:
collecting current progress data for the second segment of the plurality of segments,determining a second remaining target area value using the current progress data for the second segment, the second remaining target area value indicating a second portion of the total target area remaining to be consumed at the second content position during the second pass,determining a second remaining crash area value based on the progress data, the second remaining crash area value indicating a second portion of the total crash area that remained to be consumed at the second content position during the fist pass,calculating a second adjustment factor for the second segment of the source content as a function of the second remaining target area value and the second remaining crash area value,based on the second adjustment factor, modifying the second segment to produce a second modified segment, andappending the second modified segment to a second content portion already laid out in the total target area; and providing the data object model to a browser engine for rendering.
