Universal filter does not respect input pagesize

[colinleroy]

Hi,

When converting from PS to PDF using cfUniversalFilter, the input file's page size is lost and the output is US Letter regardless.

Minimal example:

/* Build with
 * gcc $(pkg-config --cflags libcupsfilters) main.c $(pkg-config --libs libcupsfilters) -o testps2pdf
 */
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#include <cups/cups.h>
#include <cupsfilters/filter.h>

int main(int argc, char *argv[]) {
  int input, output, status;
  cf_filter_data_t filter_data;
  cf_filter_universal_parameter_t filter_params;

  input = open("test.ps", O_RDONLY);
  if (input > 0) {
    output = open ("test.pdf", O_CREAT|O_WRONLY, S_IRUSR|S_IWUSR);
    if (output > 0) {
      memset(&filter_data, 0, sizeof filter_data);
      memset(&filter_params, 0, sizeof filter_params);
      filter_data.logfunc = cfCUPSLogFunc;
      filter_data.printer = NULL;
      filter_data.content_type = strdup("application/postscript");
      filter_data.final_content_type = strdup("application/pdf");
      filter_data.copies = 1;
      status = cfFilterUniversal(input, output, 1, &filter_data, &filter_params);
      printf("Printer: Filter status %d\n", status);
      close(output);
    } else {
      close(input);
      return -1;
    }
    close(input);
  } else {
    return -1;
  }
  return 0;
}

Output:
