Redmon postscript输出

Question

我正在使用雷德蒙重定向去输出抄本 my c# .exe来处理。打印配置与配置幽灵脚本的方式相同，但不是鬼路径，而是通知了我的.exe路径。

​

​

为了转换PDF中的postscript，我使用了幽灵脚本，如下代码所示

Stream content = Console.OpenStandardInput();
using BinaryReader standardInputReader = new BinaryReader(content);

using (FileStream standardInputFile = new FileStream(psFile, FileMode.Create, FileAccess.ReadWrite))
{
    standardInputReader.BaseStream.CopyTo(standardInputFile);
}
standardInputReader.Close();

string ghostScriptPath = @"C:\gs\gs9.52\bin\gswin64.exe";

String ars = @"-Ic:\gs\gs925\lib -dNOPAUSE -dBATCH -q -dSAFER -sDEVICE=pdfwrite -sOutputFile=teste.pdf psFile.ps";
Process proc = new Process();
proc.StartInfo.FileName = ghostScriptPath;
proc.StartInfo.Arguments = ars;
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.Start();
proc.WaitForExit();

但是ghostscript总是抛出错误%%错误:未定义；OffendingCommand: Redmon %%。

如果我使用的是幽灵脚本，而不是我的程序，一切正常，但如果我“拦截”，错误总是会发生。我记录了这两种情况下的输出，但是日志是相同的，如下所示。

完整的日志可以看到这里

好吧，如果你看看你上传的文件，它就开始了：

RedMon - Redirection Port Monitor
Copyright (C) 1997-2012, Ghostgum Software Pty Ltd.  All Rights Reserved.

REDMON WritePort: about to write 4096 bytes to port.
%!PS-Adobe-3.0

到达%!PS-Adobe的所有东西都不是PostScript，也不是由打印机驱动程序发送的。这些都是由RedMon端口监视器发送的。然后，输出以以下方式结束：

%%EOF

REDMON WritePort: OK  count=2489 written=2489
REDMON EndDocPort: starting

REDMON WriteThread: ending
%%[Page: 1]%%
%%[LastPage]%%
REDMON EndDocPort: process finished after 1 second

REDMON EndDocPort: 0 bytes written to printer
REDMON EndDocPort: ending

而且%EOF后面的所有内容都不是PostScript，而是来自端口监视器。由于所有这些都不构成有效的PostScript程序，将其发送到Ghostscript将导致某种错误。

您需要研究如何去掉这些语句，只将PostScript语言程序发送到Ghostscript。

恐怕我帮不了您，我不知道您的应用程序是如何从RedMon接收数据的。

无论如何，这并不是一个真正的Ghostscript或PostScript问题。
