Count the number of pages in a PCL file.
-
The code below, would must to show the count the number of pages in a PCL file. But, don´t show. Why?? What is wrong?? //---------------------------------- #include "stdio.h" #include "stdlib.h" #include "string.h" int main (int argc, char **argv) { FILE *InputFile; char ch, EndTag, tag[2], *InputFileName; int n, BlockSize, Pages, Copies, Quiet; unsigned long FileSize, FilePos; BlockSize =0; Pages =0; FileSize =0; FilePos =0; Copies =0; Quiet =1; InputFileName = NULL; // Parse command line parameters for(n = 1; n <= argc - 1; n++) { if(! memcmp(argv[n], "-h", 2)) { printf("Error"); exit(0); } else if(! memcmp(argv[n], "-v", 2)) Quiet = 0; else if(argv[n][0] == '-') { fprintf(stderr, "-- Parameter incorrect: '%s'.\n", argv[n]); exit(1); } else InputFileName = argv[n]; } if(InputFileName == NULL) { fprintf(stderr, "-- Must enter a file name.\n \" Use 'pclcount -h' to get help.\n"); exit(1); } // Try to open the input file if(! (InputFile = fopen(InputFileName, "r"))) { fprintf(stderr, "--Error opening file: %s\n", argv[1]); exit(-1); }; // Get the file size, to show statistics if '-v' is passed if(! Quiet) { fseek(InputFile, 0, SEEK_END); FileSize = ftell(InputFile); fseek(InputFile, 0, SEEK_SET); } while(fread(&ch, 1, 1, InputFile)) { switch(ch) { case 12: // Found FormFeed: increments page counter Pages ++; break; case 27: // Found fread(tag, 2, 1, InputFile); if(! (memcmp(tag, "*b", 2) && memcmp(tag, "(s", 2) && memcmp(tag, ")s", 2) && memcmp(tag, "&p", 2))) { /* Detect the operators: *b###W -> Start of Binary Block (s###W -> Start of Characters Description Block )s###W -> Start of Fonts Description Block &p###X -> Start of non-printable Characters Block In these operators, '###' is the size of respective block. */ // Define the block end-character EndTag = memcm

whileloop not find any ASCII 12 characters? Remember that "page eject" in PCL can be any of the following commands: RESET (EcE) PAGE SIZE (Ec&l#A) PAGE LENGTH (Ec&l#P) ORIENTATION CHANGE (Ec&l#0) PAPER SOURCE CONTROL SEQUENCE (Ec&l0H) with a value of zero PAPER SOURCE (Ec&l#H)

This program should to show the number of pages a file it be printed in format HP-PCL. Does the while loop not find any ASCII 12 characters? No, no finds. raf-sp
How about using
fopen(InputFileName, "r**b**")instead?

If you could provide me with a link to a .pcl file, I can provide you with a code snippet to do what you require. - DC
