read function throws exception of Access violation.?

[mbatra]

Hi,

I am using Magick++ to rotate an image. I have initialized the ImageMagick library also. WHen I am reading an image using read function, it throws an exception 'Access violation writing to memory location .....'.

Anybody , have any idea about this.?

Try this example (save as magick++.cpp):

Code: Select all

#include <iostream>
#include <Magick++.h>

using namespace std;
using namespace Magick;

int main() {
  try {
    Image sourceImage("logo.jpg");
    Image newImage(sourceImage);
    newImage.zoom("50x");
    newImage.write("newlogo.jpg");
  } catch (Error &exception) {
    cerr << exception.what() << '\n';
  } catch (...) {
    cerr << "Unknown exception thrown\n";
  }
}

Build with

• g++ `Magick++-config --cxxflags --cppflags` -o magick++ magick++.cpp `Magick++-config --ldflags --libs`

Now run:

• convert logo: logo.jpg
  ./magick++

If that fails, try with the latest release of ImageMagick, 6.7.8-7 @ http://www.imagemagick.org/download/. If that also fails, get a stack trace and post it here:

• gdb ./magick++
  run
  where

Hi,

Thanx for the reply.
I am using windows operating system and VS2010 IDE. This throws the same exception at the first line in try block.

Image sourceImage("logo.jpg");

Image exists in the specified path.
