quando tento imprimi-lo, posso imprimir apenas metade dele. Felizmente, posso visualizá-lo no visualizador de documentos integrado do Ubuntu (posso acessar todas as páginas, mas não posso imprimi-las em um arquivo).

Como posso corrigir esse arquivo postscript específico e convertê-lo em pdf?

    

Answer 1

O problema é que um arquivo PS é um programa executável e pode executar ações impróprias, o que perturba a máquina virtual do ghostscript. Eu tinha localizado, a julgar pela posição retornada pelo ghostscript, quais são as páginas ofensivas; essas são as páginas 234 (36) e 250 (52). Então eu abri o arquivo .ps em um editor de texto e procurei por "%% Page: 234" e "%% Page: 250" e literalmente os recortei (até a próxima declaração %% Page) e alimentei o. ps arquivo para ghostscript (sem erros). Agora eu tenho um PDF sem 2 páginas.Essas páginas podem ser corrigidas por alguém que é bom em PostScript.
