of bitmap images. convert input-file [options] output-file
OVERVIEW
ImageMagickTM, version 6.2.0, is a free software suite for the creation, modifica-
tion and display of bitmap images. It can read, convert and write images in a large
variety of formats. Images can be cropped, colors can be changed, various effects
can be applied, images can be rotated and combined, and text, lines, polygons,
ellipses and Bezier curves can be added to images and stretched and rotated.
ImageMagick is free software: it is delivered with full source code and can be
freely used, copied, modified and distributed. Its license is compatible with the
GPL. It runs on all major operating systems.
Most of the functionality of ImageMagick can be used interactively from the command
line; more often, however, the features are used from programs written in the pro-
gramming languages Perl, C, C++, Python, PHP, Ruby, Tcl/Tk or Java, for which
ready-made ImageMagick interfaces (PerlMagick, Magick++, PythonMagick, MagickWand
for PHP, RMagick, TclMagick, and JMagick) are available. This makes it possible to
modify or create images automatically and dynamically.
ImageMagick supports many image formats (over 90 major formats) including popular
formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF.
ImageMagick includes a number of command-line utilities for manipulating images.
Most of you are probably accustom to editing images one at a time with a graphical
user interface (GUI) with such programs as gimp or Photoshop. However, a GUI is not
always convenient. Suppose you want to process an image dynamically from a web
script or you want to apply the same operations to many images or repeat a specific
operation at different times to the same or different image. For these types of
operations, the command-line image processing utility is appropriate.
In the paragraphs below, find a short description for each command-line tool.Click
on the program name to get details on the program usage and a list of command-line
options that alters how the program performs. If you are just getting acquianted
with ImageMagick, start at the top of the list, the convert program, and work your
way dowm. Also be sure to peruse Anthony Thyssen's tutorial on how to use ImageMag-
ick utilities to convert, compose, or edit images from the command-line.
convert
convert between image formats as well as resize an image, blur, crop,
despeckle, dither, draw on, flip, join, re-sample, and much more.
identify
describes the format and characteristics of one or more image files.
mogrify
resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sam-
ple, and much more. Mogrify overwrites the original image file, whereas,
convert writes to a different image file.
composite
overlaps one image over another.
montage
create a composite image by combining several separate images. The images
are tiled on the composite image optionall adorned with a border, frame,
image name, and more.
compare
mathematically and visually annotate the difference between an image and its
reconstruction..
display
displays an image or image sequence on any X server.
animate
animates an image sequence on any X server.
import saves any visible window on an X server and outputs it as an image file.
You can capture a single window, the entire screen, or any rectangular por-
tion of the screen.
conjure
interprets and executes scripts written in the Magick Scripting Language
(MSL).
