Abstract: Facing on the issues when the press publishes digital content across the terminals, this paper lays special stress on the research of technologies on layout information extraction and across terminal adaptive recombination for the PDF document. The methods of extraction and layout structure analysis to the texts and pictures in the PDF document are proposed. Then the terminal adaptive recombination algorithm is applied to publish the digital content across the terminals. A set of publishing system through which the digital content is published across the terminals based on the above technologies. The experimental results prove that the approach is practical in real-world application.
