Most examples use a backslash ' \' at the end of a line toĬontinue that command on the next line. As a consequence, some examples use shell 'for-do' Generally results in improvements and expansions to these example pages.Īll examples are written for use on UNIX, and specifically GNU/Linux systems, I look forward to suggestions and e-mail from other IM users. Other examples were grabbed or developed from answers to users' questions onįorums, or contributed to me as solutions to various problems. To look at it, learn, and make comments on it. So, it may be vague or chaotic in places. Were designed for you to look at, the hints and tips document was only for my Pages, are still present in that document. Information on many aspects of IM, and notes not included in these These pages were developed from, and are a continuation of, my Collection of ImageMagick Hints and Tips page I first started in 1993,Īnd placed on the new fangled world-wide-web making its appearance around the About These Examples of ImageMagick Usage However, specific optionsĬan be used to improve this situation. Processed badly when using the default settings. Images into a raster when loading them, and generating a vector image wrapperĪround the raster when saving it. Image formats like Postscript or PDF, but at the cost of converting those ImageMagick concerns itself mainly with images in the form of a rectangularĪrray of pixels, commonly called a "raster." It will handle "vector" Operations, especially when attempting to compress images into image formats Because of this, IM can be slow to perform certain processing Transform images in a reasonable amount of time.
Speed was never a major feature of IM, which places more emphasis on the These can beĪccess via the command line and shell/DOS scripts (which these example pagesĭemonstrate), or via a large number of programming languages, such as C, C++, That is, it will convert an image in just aboutĪny image format (tell us if it can't) to any other image format.īut it is also a library of image processing algorithms. ImageMagick is, first of all, an image-to-image converter. Processing tool, panorama generator, etc. The operations can be applied to many images, or asĪ sub-system of some other tool, such as a Web application, video Image processing operations in a script (shell, DOS, Perl, PHP, etc.) so ImageMagick Examples - Introductory Notes What is ImageMagick? A No-Holds-Barred Summary ImageMagick isĭesigned for batch processing of images. Legend for symbols used within example pages. Most of the common "how-to" questions that arise.ĭevelopment proposals and bugs, new and old The examples in these web pages, I hope, will answer Often, the same questions of " How do I." gets asked, over and overĪgain on the network. Should be the first stop for IM users after reading the terse Command The ImageMagick Application Programming Interface (API). They also illustrate what can be done using However, they often have direct analogs in the current release of ImageMagick, version 7. These web pages presents a set of examples using ImageMagick ("IM," for short), version 6, from the command line. I think it is easier to remember than the elegant method by Steeldriver (who uses only convert and no for construct).ImageMagick v6 Examples Examples of ImageMagick Usage This works in bash, which is the standard shell of Ubuntu. The following one-liner should do the job for f in. Of the array in turn, and the expansion is the resultant list. Subscripted with or *, the pattern removal operation is applied to each member The pattern removal operation is applied to each positional parameter in turn,Īnd the expansion is the resultant list. Longest matching pattern (the ``%%'' case) deleted. Value of parameter with the shortest matching pattern (the ``%'' case) or the If the pattern matches a trailing portion of theĮxpanded value of parameter, then the result of the expansion is the expanded The word is expanded to produce a pattern justĪs in pathname expansion. In a for loop it is possible to use the features described in man bash at Parameter Expansion
