For example, you can prepare a texture or pattern and then tile it over an image, or prepare a mask and then alter it and apply it later in the same processing without going to disk. This is an invaluable feature present in ImageMagick that allows you to write intermediate processing results to named chunks of memory during processing without the overhead of writing to disk. None of these are mentioned in the GM source code. ImageMagick supports many types of convolution: There appears to be no support for High Dynamic Range Imaging in GM - just 8, 16, and 32-bit integer types. So, for Canny Edge Detector, I ran the following command on the GM source code: find. I freely admit I am not as familiar with GraphicsMagick as I am with ImageMagick, but I made my very best effort to find any mention of the features in the most recent GraphicsMagick source code. My experience is that there are many features missing from GraphicsMagick which are present in ImageMagick and I list some of these below, in no particular order. There is one very clear winner here - ImageMagick. However, if speed is your most important consideration, I think you should probably be using either libvips, or parallel code on today's multi-core CPUs or heavily SIMD-optimised (or GPU-optimised) libraries like OpenCV. I am happy to concede that GraphicsMagick may be faster for some, but not all problems. ImageMagick followers on SO outnumber GraphicsMagick followers by 15:1 ((387 followers versus 25 at May 2019). ImageMagick questions on SO outnumber GraphicsMagick questions by a factor of 12:1 (7,375 questions vs 611 at May 2019), and.Having answered around 2,000 StackOverflow questions on ImageMagick over the last 5+ years, I make the following observations. So it is with ImageMagick and GraphicsMagick. And if you ask a sports photographer he'll tell you the one with the fastest autofocus and highest frame rate. Ask a studio photographer, and he'll tell you the highest resolution one with the best flash sync speed. If you ask a landscape photographer who wanders around in the rain in Scotland's mountains which is the best camera in the world, he's going to tell you a light-weight, weather-sealed camera. I'm out of ideas on how to make PHP use the ImageMagick 7.As with many things in life, different people have different ideas about what is best. I even tried to remove the ImageMagick 6.9.7 and the PHP-Imagick extension, I thought that by reinstalling the extension with only one version available, it will somehow point at that but the extension couldn't be installed without ImageMagick6.
