ImageMagick++ - ErrorMissingDelegate at memorry location
-
I have downloaded and installed ImageMagick++ from http://www.imagemagick.org/Magick++/. I am using Windows7 32 bit and Visual Studio 2008. I want to use the ImageMagick in an existing project. I made the required/suggested changes to my project properties like adding dependencies etc. I added three libraries in the additional dependencies (CORE_RL_Magick++_.lib,CORE_RL_MagickCore_.lib and CORE_RL_MagickWand_.lib I added Magick++.h header file and using namespace Magick Then Magick:: Image image (No error) image.read("5.png") throws an error "ErrorMissingDelegate at memorry location ....". I tried other image formats also, but same error. Please help.

Would be good to know the complete error message. A quick search in ImageMagick/constitute.c at master · ImageMagick/ImageMagick · GitHub[^] shows that the
ReadImage
function reports delegate errors with "NoEncodeDelegateForThisImageFormat". Searching this in the net gives the answer: You have to install delegates for the image formats to be used. -

The complete message is Magick::ErrorMissingDelegate at memory location 0x0012fafc. I can understand there are some missing delegates but I really do not understand how do I have to install them.

I have only used ImageMagick on Linux so far and never build it (used the distribution binaries). You should read the provided documentation: Advanced Windows Installation[^] Read the "ENVIRONMENT VARIABLES" section and check if your build has created the required modules. If not, check the build configuration. To check if it works in general, use an image format that does not require a delegate like GIF or JPEG. If you are still stuck you might get better help in one of the ImageMagick Forums[^] (or even find the solution in an existing thread or FAQ there).

Thanks again. I am also using the Windows Binaries. I tried with GIF and JPEG but same error message.

Have you initialised the library?
Note, under Windows (and possibly the Mac) it may be necessary to initialize the ImageMagick library prior to using the Magick++ library. This initialization is performed by passing the path to the ImageMagick DLLs (assumed to be in the same directory as your program) to the InitializeMagick() function call. This is commonly performed by providing the path to your program (argv[0]) as shown in the following example: int main( int argc, char ** argv) { InitializeMagick(*argv); ...
and copied the DLLs to the path of your executable (Debug resp. Release) or used the path to the DLLs?

Thanks for the reply. Yes, it is as advised by you. I am not even able to run the demo project (Button) provided with the Windows Binary Installer.

Then I'm not able to help anymore. I can only suggest to check your installation (all required modules present) and the setup (e.g. all required pathes set).

Hi, Sounds like you are compiling ImageMagick without any image libraries.

LIBPNG[^] LIBJPEG[^] LibTIFF[^] Many others... Then recompile with: ./configure --with-png=yes --with-jpeg=yes --with-tiff=yes It can be alot of work... you might be better off downloading a precompiled binary: Install from Binary Distribution @ ImageMagick[^] Best Wishes, -David Delaune
