Hi
I am trying to install ImageMagick to use with MagickWand under Visual Studio 9.0.
I began by getting a binary installer and getting ImageMagick to work. That worked OK. I tried running a program containing the example code wand.c and found this install had come with no source files.
I re-downloaded ImageMagick 6.6.2, and managed to find a file which does come with some .c and .h files in folders called /wand and /magick.
It also comes with a file called Install-windows.txt which talks all the time about "VisualMagick" but I have nothing called that. Nor does the whole ImageMagick-6.6.2-6 tree include any .dsw or .sln files. (It talks about a configure directory containing configure.sln ???).

I tried just to copy the /wand and /magick folders to my /include folder, but it then won't compile a project with the wand.c code because it says an error about not finding a ghostscript header file. I cannot even find on the web a source code for ghostscript that is not a tarball (*and I never wanted to install ghostscript*). I commented out the hasGS #define in magick-config.h but this had no effect! Clearly there is something else that needs rebuilding first (???).

My preferred way of doing things would be to make ImageMagick a static library that lives in my application. I thought I might struggle a bit with linking it in VS (if there is a guide to that, rather than just some command-line compiler switches, that would also be useful), but it's seeming like I can't get even that far...
Any help appreciated.

Further to that.

I eventually discovered that the sourceforge mirror of ImageMagick includes this VisualMagick part. Apparently I then built it, but not sure after all what I achieved by that.

Coming back to my effort of just copying /wand and /magick into my /VC/include directory, I installed ghostscript from executable and unsurprisingly it made no difference. So I just deleted the #include for ghostscript in delegate.h, and did likewise for a couple of other similar errors.
Had then to modify the example code a little to avoid compiler errors for undeclared variables - relevant bit of my code now looks like

Code: Select all

	MagickWand * magick_wand;
	int status;

	MagickWandGenesis();
	magick_wand=NewMagickWand();  
	status=MagickReadImage(magick_wand,"doxygen.png");
	if (status == MagickFalse)
    ThrowWandException(magick_wand);
  /*
    Turn the images into a thumbnail sequence.
  */
	MagickResetIterator(magick_wand);
	while (MagickNextImage(magick_wand) != MagickFalse)
    MagickResizeImage(magick_wand,106,80,LanczosFilter,1.0);
  /*
    Write the image then destroy it.
  */
	 status=MagickWriteImages(magick_wand,"bonk.png",MagickTrue);
	if (status == MagickFalse)
		ThrowWandException(magick_wand);
	magick_wand=DestroyMagickWand(magick_wand);
	MagickWandTerminus();

within a Windows program that is just the standard one that VS creates when you create a new Win32 project. I then get a linking error, as I really do not know how to link to the ImageMagick library, or where it lives.

The install-windows.txt file says

You can feel free to pick any of the standard utilities, tests, or demo
programs as the basis for a new program by copying the project and the
source and hacking away.

However, I don't feel free to do that, because for one thing I'm trying to write a Win32 application (I want to see my plots on screen before I save them, and I already know how to do that with Windows bitmaps, I don't want to do anything differently).

I thought the idea of the VisualMagick bit was to compile a static library file that I could then link to, but it seems to compile bunches of utility executables.

Well anyway, if anyone knows a simple way to link an ImageMagick static library into a VS Win32 project, please help.
