Image manipulation library for console?

Shioni · 03-25-2006, 06:15 AM

Hi!
I want to create image manipulation plugin for my website, but I want to create it as consule application, not GUI! My plugin will add graphic filters to uploaded images and saves them. I want to write this in C. Does anyone know any library etc..? Thank you!

You might want to look at ImageMagick-devel.

Also, look into the interfaces for ImageMagick, such as C, Perl, PHP, and Ruby. It may not be necessary to write your own C code to do what you want to do.

And the unruly twin to ImageMagick is GD2.

Thanks! But aren't there standart image manipulation libraries? or something that I can #include in my C code?

Image Magick *is* a standard image manipulation library.

And you *can* include it in your C code.

Or C++ code. There are also ImageMagick bindings to Perl, Python and many other languages.

Oh - and it has a CLI that you can script from bash (on Linux) or even a .bat file (on Windows)!

It's great, it's incredible, it's easy to use, it's powerful, it's flexible.

Do you kind of get the impression I like ImageMagick?

I think you will, too!

Yes i have used it its great tool for command line users

Thank you! I can't find any tutorial about how to #include ImageMagick and GCC. Can anyone give me any link or something, I have searched in google, but I can't find anything!!!

As far as I understood, ImageMagick is like command line image manipulation app, and all I can do with it in C is system("...");??? so it isn't posible to use it in C as a librarie?

Graemef already gave you a link (he gave you two links, in fact: one to Image Magick, the other to GD2).

Several people have already explained to you that ImageMagick is *BOTH* a library (callable from C, Python, Perl and other languages) *AS WELL AS* a set of command line tools (which you can invoke from a shell script or a .bat file).

Now please re-read the previous posts: they should answer your questions.

Thanks, but I can't find a single tutorial about using ImageMagick in GCC!!

Sigh...

Here are some links that I found helpful:

http://www.imagemagick.org/script/magick-core.php
http://www.graphicsmagick.org/www/api/types.html
http://www.graphicsmagick.org/www/ap...ireimagepixels

http://www.aerophile.org/ImageMagick...antize_8c.html
http://library.n0i.net/linux-unix/ap...k/www/api.html

Here's cut/paste of a simple ImageMagick "Hello world":

Code:

#include <stdio.h>
#include <string.h>
#include <errno.h>
#include <stdlib.h>
#include <magick/api.h>

int
main (int argc, char *argv[])
{
  // Check arguments
  if (argc < 2)
  {
    printf ("USAGE: psm060203a <*.png files list>\n");
    return 1;
  }

  // Init ImageMagic
  InitializeMagick(argv[0]);
  ...
  // Cleanup ImageMagic
  printf ("Closing ImageMagick...\n");
  if (images)
    DestroyImages (images);
  if (image_info)
    DestroyImageInfo(image_info);
  DestroyMagick();

  return 0;
}

I've used Imlib2 on a number of occasions and like it. You can find documentation and stuff on the enlightenment site (www.enlightenment.org ?).
