提出的算法可以解决在嵌入式系统上显示含有文本和图像的PDF 文件的要求。该算法先将PDF 文件分解成图像和文本两部分，然

后依照原文件的显示格式将分解出来的元素合成一种新的格式文件，最终实现将PC 机上的PDF 格式文件转化为适合在嵌入式系统上正确显示的格式。该算法缩减了文件的大小，使之适应于嵌入式系统有限的硬件资源，也扩大了嵌入式系统的文件来源。-The proposed algorithm can solve embedded system with text and images displayed on the PDF documents. The algorithm first PDF file into two parts, image and text, and then display format in accordance with the original file will be decomposed by the elements to synthesize a new format, and ultimately on the PC, converted to PDF format suitable for use in embedded systems The format shown on the right. The algorithm to reduce the file size, to adapt them to embedded systems with limited hardware resources, but also to expand the files from the embedded system.
