从一个文件中提取聚苯乙烯聚苯乙烯和聚苯乙烯图像

PS Extractor is a python script that will extract most eps and ps images from a PS document. It is based on the idea on http://www-hermes.desy.de/notes/extras/postscript.html, but further improved with the use of ProcSets. It still needs some improvements, but I think it is a good starting point. I"ve tested the program with 6 different ps files and with 5 of them it works OK. But with the other, the bounding box can not be computed correctly because in order to show all the image, should have negative bounding box.
