Koen, sorry for the long delay too.
I had not found examples that used the GraphicsMagick, but now its working:
#include <cstring>
#include <magick/api.h>
#include "graphicsmagicks.h"
GraphicsMagicks::GraphicsMagicks(std::string in, std::string out) {
try {
ImageInfo *image_info;
ExceptionInfo exception;
InitializeMagick(0);
GetExceptionInfo(&exception);
image_info = CloneImageInfo((ImageInfo *) NULL);
const int argc = 8;
char *argv[argc] = { (char*)"convert", (char*)in.c_str(),
(char*)"-geometry", (char*)"800x800>", (char*)"-quality", (char*)"75",
(char*)out.c_str(), (char*)NULL };
int status = ConvertImageCommand(image_info, (argc-1), argv,
(char**)NULL, &exception);
DestroyImageInfo(image_info);
DestroyExceptionInfo(&exception);
DestroyMagick();
} catch (...) { }
}
in CMakeList.txt:
include_directories(/usr/include/GraphicsMagick)
target_link_libraries(GraphicsMagick)
