![]() ![]() Contributions and test examples are welcome. ![]() #Imagemagick convert windowsSee Windows Usage and APIsand Scripting for more information on using the ImageMagick commands inthese alternative environments. Withsome slight adaptation, the examples can also be run directly from' system' calls in PHP scripts. #Imagemagick convert PcHowever, you can still use these examples from PC Windows batchscripts, with some changes to the handling of certain characters. The longer commands are broken intoseparate lines to try to further highlight the steps being applied. Most examples use a backslash ' \' at the end of a line tocontinue that command on the next line. As a consequence, some examples use shell 'for-do'loops. Command Line EnvironmentsĪll examples are written for use on UNIX, and specifically GNU/Linux systems,using BASH scripting. Such e-mailgenerally results in improvements and expansions to these example pages. I look forward to suggestions and e-mail from other IM users. Other examples were grabbed or developed from answers to users' questions onhe IMForums, or contributed to me as solutions to various problems. You are welcometo look at it, learn, and make comments on it. So, it may be vague or chaotic in places. However, while the present pageswere designed for you to look at, the hints and tips document was only for myown edification. Information on many aspects of IM, and notes not included in thesepages, are still present in that document. These pages were developed from, and are a continuation of, my Collection of ImageMagick Hints and Tips page I first started in 1993,and placed on the new fangled world-wide-web making its appearance around thesame time. About These Examples of ImageMagick Usage However, specific optionscan be used to improve this situation. As a result, vector images are oftenprocessed badly when using the default settings. ![]() ImageMagick concerns itself mainly with images in the form of a rectangulararray of pixels, commonly called a "raster." It will handle "vector"image formats like Postscript or PDF, but at the cost of converting thoseimages into a raster when loading them, and generating a vector image wrapperaround the raster when saving it. Because of this, IM can be slow to perform certain processingoperations, especially when attempting to compress images into image formatsthat have limited capabilities. That is not to say that it can'ttransform images in a reasonable amount of time. ![]() Speed was never a major feature of IM, which places more emphasis on thequality of the images it generates. These can beaccess via the command line and shell/DOS scripts (which these example pagesdemonstrate), or via a large number of programming languages, such as C, C ,Perl, Ruby, PHP, etc. That is, it will convert an image in just aboutany image format (tell us if it can't) to any other image format.īut it is also a library of image processing algorithms. That is what it wasoriginally designed to do. ImageMagick is, first of all, an image-to-image converter. That is, it allows you to combineimage processing operations in a script (shell, DOS, Perl, PHP, etc.) sothe operations can be applied to many images, or asa sub-system of some other tool, such as a Web application, videoprocessing tool, panorama generator, etc. ImageMagick isdesigned for batch processing of images.
