As a result, PDF viewers allow the user to quickly jump to the final pages of a long document, whereas a PostScript viewer needs to process all pages sequentially before being able to display the destination page (unless the optional PostScript Document Structuring Conventions have been carefully complied with).
结果PDF查看器允许用户迅速跳转到长文档的最后一页，而一个PostScript查看器需要在能够显示目标页面之前继续地处理所有的页面（除可选PostScript文档结构规范（英语：Document Structuring Conventions）已被周密地遵守外）。
