如何计算后记中的页面

Question

I'm developing a C# Console Application and have to count the pages of a PostScript file. Is there an easyer way to count the pages other then parsing the text in the file.

Thanks!

Answer 1

If the file contains an arbitrary PostScript program, the only way is to execute the file, perhaps after redefining the showpage operator to count the number of pages.

If the file follows the DSC conventions, then you can count %%Page comments or perhaps directly use %%Pages if present.
