Fixed the issue by using 'unsigned char' for CharPixels.

I'm still having issues with pixel input, is it possible to simply get 8-bit grayscale intensities for an image? e.g. The value for any pixel is between [0 .. 255] I have tried the following without success. char *pixels = new char[width*height]; image.write( 0, 0, width, height, "I", CharPixel ...

My current development machine is a a slightly old single core, so OpenMP wont help until I get a new system :) I'm implementing a generalization of the radon transform, the trace transform so the included method wouldn't really help. Here is what I am doing: Read input image (various formats ...

Thanks magick.

Do you know which is faster? I'm writing a modified radon transform algorithm on a couple million images so speed is very important.

All I want to do is to read the image, run a Gaussian blur and then get pixel intensities into an array as fast as possible.

I see this is possible in C, using MagickWand and/or MagickCore. The closest method in Magick++ seems to be getPixel, however this returns a PixelPacket. How can I simple get a double of intensities as there is no way to pass the map to this function. Would it be faster to just use libs to read ...

Hi,

I'm trying to get an array of pixel intensities for an image with ImageMagick in C++ via Magick++.

I found out how to do it in Perl: How can I do the same in C++?
