PostScript文件与PDF文件间数据转换

The data conversion of PostScript files and PDF files

针对可变数字印刷中常用的页面描述语言及其文件格式,通过研究PostScript文件结构和PDF文件结构,介绍了如何实现PostScript文件与PDF文件间的数据转换,给出两种文件间转换算法流程图,并利用PostScript解释器Ghostscript提供的API接口,实现了PostScript文件和PDF文件间的转换。转换结果表明,该转换算法转换效果比较好,实现了所见即所得。

Considering the usual page description language and file format in variable digital printing, this paper introduces how to realize the conversion between PostScript files and the PDF files base on their structure. Then gives the conversion flow chart and realize the conversion by using the API interfaces of PS interpreter Ghostscript . The conversion results show that this conversion effect is better, realize what you see is what you get.
