Profile in dpx format image

[albertoii]

Hi

Sorry for my bad english.
I'm using Magick wand and programming in c.
I need some help, I need to apply an ICC profile to a tiff image and transform it into dpx format. I have achieved my goal but only if the final image is a jpg one, if i change the code and put dpx extension to the final image, I get the image but it doesn't apply the profile.
Can somebody help me??? I can't find the mistake. So, please, if you know how, tell me.


Thank you

Do you want to set a profile or transform the colorspace with a profile? If the latter, did you call MagickProfileImage()? You need to first set the image profile and then call MagickProfileImage() with a profile to use to transform the colorspace.

I want to apply an icc profile.
This is what i do:

Code: Select all

magick_wand=NewMagickWand();
status = MagickReadImage(magick_wand, original_file);
MagickResetIterator(magick_wand);

while (MagickNextImage(magick_wand) != MagickFalse){
      MagickProfileImage(magick_wand,"ICC",ICC,size);
}
status = MagickWriteImages(magick_wand,destination_file,MagickTrue);
if (status == MagickFalse)
      printf("error writting the image");
magick_wand=DestroyMagickWand(magick_wand);

original_file is a file with .tif extension like example.tif
and here is the doubt if destination_file is a file with .jpg extension like example.jpg, it works perfectly but if i change it into .dpx extension like example.dpx the result is the image without the profile applied.

I have also tried with MagickSetImageProfile and it doesn't work too.

I don't why it happens.


Thank you

We'll need to reproduce the problem. Post the shortest script possible that illustrates the problem and a URL to your input image, profile, and output JPEG and DPX images. We need to reproduce the problem before we can offer additional help.

I have been looking for other profiles, and finally I realized that the problem was that. I was using a bad ICC profile.

I post my code here anyway:

Code: Select all

#include <string.h>
#include <unistd.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <stdio.h>
#include <wand/magickwand.h>

int main(int argc, char *argv[])
{
  
  if(argc<3)
    {
      fprintf(stderr,
	      "%s original_image destination_image ICC_profile\n",argv[0]);
      system("PAUSE");
      return -1;
      }
  
  
  ///////////////////////////////////////
   //Start reading ICC profile
   ///////////////////////////////////////
   size_t size=0;
   FILE *file;
   int numRead;
   unsigned char buffer[2048];
   if ((file=fopen(argv[3],"rb"))==NULL){
      fprintf(stderr,"Error while opening ICC profile\n");
      system("PAUSE");
      return -1;
      }
   else{
        while ((numRead = fread(buffer,1,2048,file))){
              size+=numRead;
              }
   }
   //This will be variable with the ICC profile
   unsigned char ICC[size];
   rewind(file);
   fread(ICC, 1, size, file);
   fclose(file);

   //////////////////////////////////////////////
     
  MagickWand *magick_wand;
  MagickBooleanType status;
   
   MagickWandGenesis();
   
   magick_wand=NewMagickWand();
   status = MagickReadImage(magick_wand, argv[1]);
   MagickResetIterator(magick_wand);
   if (status == MagickFalse){
      fprintf(stderr,"error reading the image\n");
      system("PAUSE");
      return -1;}
   MagickProfileImage(magick_wand,"ICC",ICC,size);
    status = MagickWriteImages(magick_wand,argv[2],MagickTrue);
    if (status == MagickFalse){
      fprintf(stderr,"error writting the image\n");
      system("PAUSE");
      return -1;}
    magick_wand=DestroyMagickWand(magick_wand);
  
    MagickWandTerminus();
    system("PAUSE");
  return 0;
}

Thank you for all.
