HDRI ImageMagick
Nov 6, 2013

For a while now, I’ve been using ImageMagick for resizing, since it appears to give slightly better results compared to Photoshop CS5. Lately, I read this article by forum participant Nicolas Robidoux:

http://www.imagemagick.org/Usage/filter/nicolas

…which recommends using a high definition version of this software which uses extended precision calculations. As these HDRI binaries weren’t available for my Mac, I had to compile the software using the Xcode command line tools, and I had to download the right version of Xcode for my machine.

Various versions of ImageMagick are available, and the latest works on my Mac — downloading the source code was easy, but building it was not trivially straight forward. After I managed to build the software, it still wouldn’t work — it turns out that support for JPEG and TIFF files is not included in the source code, so I had to track down third-party modules to work with these.

While the build notes are straight-forward, some knowledge of UNIX commands are essential — such as navigating the hidden folder hierarchy and creating new directories using the command line.
