You may see several of these lines followed by a line that starts with “loading delegate configuration file”. Search the debugging information for a line that starts with “searching for configure file”. It will log copious debugging information to the console. Run the following command: magick -debug "all" abc.xyz test.jpg We will tell it to output to JPEG, in file test.jpg (however, it will error out before it gets there because the input file does not exist). It will error out, but we will still get the debug information. We can just use an input file that does not actually exist and has a nonsensical extension, such as “abc.xyz”. To do this, we will want to run ImageMagick’s convert utility on an example file, and have it write debugging information to the console. However, in case there are multiple copies, it can be useful to know which one has precedence (which one ImageMagick is checking first). You may be able to simply search your system for “delegates.xml”. ImageMagick looks in a number of different places for this file, and it is possible to have more than one copy. The exact location of your delegates.xml file depends on the details of your installation and your operating system. To have ImageMagick use RawTherapee to convert raw camera files, we will need to edit the delegate decode="dng:decode" line of the delegates.xml file. The delegates.xml file serves as a reference and configuration file for ImageMagick to build the command-line commands to call these applications with the correct parameters to handle the file that is at hand. It also does this with a number of other applications to which it delegates various file types, such as PDFs and Office documents. ImageMagick calls UFraw and DCraw via the terminal. Instead, we configure it and build it with modules: $ cd ImageMagick-7.1.0 Note that we should not directly configure and compile it with the default settings. #RAWTHERAPEE WINDOWS INSTALL#In order to use LibRaw as a raw image decoder instead of other default options in ImageMagick, we need to install and build ImageMagick from the source. #RAWTHERAPEE WINDOWS DOWNLOAD#Libx11-dev libxext-dev zlib1g-dev libpng12-dev \Īfter installing the required libraries, we can then download the LibRaw ubuntu package by using apt-get. If we want to convert the raw image into any commonly used image type, then the corresponding packages are required: $ sudo apt-get install build-essential checkinstall \ ImageMagick requires the following dependencies for the decode delegate for certain image formats. A couple of alternatives for UFraw and DCraw are Libraw and RawTherapee. #RAWTHERAPEE WINDOWS FULL#In our specific examples, they came across full color but with a heavily yellowish tint.īecause of this, programmers and system administrators whose applications rely on ImageMagick for the conversion of raw camera files may wish to consider changing how ImageMagick handles these files. In our testing, the images that converted into shades of pink in UFraw converted better in DCraw, but they still did not look right. This means that these images might not look right when converted – for example, in our testing, we found images from one newer camera ended up converting into shades of pink, rather than full color.ĭCraw has had more recent updates than UFraw, but DCraw’s development has also stalled within the past couple of years. The use of UFRaw as a delegate of ImageMagick has presented some challenges in recent years, largely due to the fact that the open-source UFRaw project has not been maintained in several years, and the project is not being updated for newer cameras. #RAWTHERAPEE WINDOWS WINDOWS#On Windows systems, ImageMagick delegates to DCraw. Although it natively handles a wide range of standard image files, such as JPEG and PNG, when it needs to handle raw camera files, it delegates the conversion of these files to other command-line utilities that are included in the ImageMagick installation. ![]() ImageMagick itself also delegates to other open-source programs when it needs to handle certain types of files. Because it is open-source and has these command-line utilities, it has ended up being widely used in other open-source projects that need to handle images programmatically. ![]() These command-line utilities are very powerful and can be used to programmatically edit and convert images, such as photographs, and even to programmatically create new images, such as procedurally-generated slates for video projects. It has both a graphical user interface as well as command-line utilities. It was first created in 1987 and has been maintained and developed since then. #RAWTHERAPEE WINDOWS SOFTWARE#ImageMagick is open-source software for running a wide range of operations on images.
