Morphology from Magick++ to match Command line Convert - c++

Question

I am trying to duplicate the ImageMagick command line:
Convert In.jpg ( -bias 50% -morphology Convolve LoG:0x1.5 ) Out.jpg
via the Magick++ in C++ (visual Studio 2010 Express)
I have read that the morphological operations are not part of Magic++ so the C MagickCore functions need to be used. I am unable to obtain output that matches (or is even close) to
ImageMagick command line output.
I am attempting to create the Kernel via
k=MagickCore::AcquireKernelInfo("LoG:0x1.5");
and execute the morphology via
m = MagickCore::MorphologyImage(i, MagickCore::ConvolveMorphology, 3, k, e);
I am guessing at these methods and parameters due to lack of information on specifics.
Does anyone have guidance on how to accomplish the same output from C++ ?

Answer 1

To accomplish these operations in Magick++ would require many tedious steps that I have no documentation on. The kernel creation is especially dubious as it came out as 13x13.
I found another way to accomplish the same goal: Use the MagickCore::ConvertImageComand(). The parameters are the same as the command line version and the output is the same. Using the command from C++ seems to work without problems...
using namespace Magick;
char *args[]={"convert", "In.jpg","(","-bias","50%","-morphology", "convolve", "LoG:0x1.5", ")","Out.jpg" };
int args_count = 10;
MagickCore::ExceptionInfo *exception = MagickCore::AcquireExceptionInfo();
MagickCore::ImageInfo *image_info = MagickCore::AcquireImageInfo();
(void) strcpy(image_info->filename,"In.jpg");
image = MagickCore::ReadImage(image_info, exception);
MagickBooleanType status =
ConvertImageCommand(image_info, args_count, args, NULL, exception);
I would prefer to have this operation result in a buffer or in-memory image rather than writing to the disk but I guess that is another question...

The next version of ImageMagick (6.8.8-7) will have support for morphology in the Magick++ API. Your command:
convert In.jpg -bias 50% -morphology Convolve LoG:0x1.5 Out.jpg
can be written like this:
Magick::Image img;
img.read("In.jpg");
img.artifact("convolve:bias", "50%");
img.morphology(ConvolveMorphology, LoGKernel, "0x1.5");
img.write("Out.jpg");
