如何使用Ghostscript将PostScript文件转换为PDF文件格式:
/* Example of using GS DLL as a ps2pdf converter. */#if defined(_WIN32) && !defined(_Windows)
# define _Windows
#endif
#ifdef _Windows
/* add this source to a project with gsdll32.dll, or compile it directly with:* cl -D_Windows -Isrc -Febin\ps2pdf.exe ps2pdf.c bin\gsdll32.lib*/
# include <windows.h>
# define GSDLLEXPORT __declspec(dllimport)
#endif#include "ierrors.h"
#include "iapi.h"void *minst = NULL;int main(int argc, char *argv[])
{int code, code1;const char * gsargv[7];int gsargc;gsargv[0] = "";gsargv[1] = "-dNOPAUSE";gsargv[2] = "-dBATCH";gsargv[3] = "-dSAFER";gsargv[4] = "-sDEVICE=pdfwrite";gsargv[5] = "-sOutputFile=out.pdf";gsargv[6] = "input.ps";gsargc=7;code = gsapi_new_instance(&minst, NULL);if (code < 0)return 1;code = gsapi_set_arg_encoding(minst, GS_ARG_ENCODING_UTF8);if (code == 0)code = gsapi_init_with_args(minst, gsargc, gsargv);code1 = gsapi_exit(minst);if ((code == 0) || (code == gs_error_Quit))code = code1;gsapi_delete_instance(minst);if ((code == 0) || (code == gs_error_Quit))return 0;return 1;
