ImageMagick - Convert, Edit, and Compose Images
Description: ImageMagick is a robust collection of tools and libraries to read, write, and manipulate an image in many image formats including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color reduce, or add special effects to an image or image sequence and save your completed work in the same or differing image format. Image processing operations are available from the command line, as well as through C, C++, Perl, or Java programming interfaces.

Synopsis
| import [ options ... ] file
Description
| Import reads an image from 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 portion of the screen. Use display for redisplay, printing, editing, formatting, archiving, image processing, etc. of the captured image. The target window can be specified by id, name, or may be selected by clicking the mouse in the desired window. If you press a button and then drag, a rectangle will form which expands and contracts as the mouse moves. To save the portion of the screen defined by the rectangle, just release the button. The keyboard bell is rung once at the beginning of the screen capture and twice when it completes.

Examples
| To select an X window or an area of the screen with the mouse and save it in the MIFF image format to a file entitled window.miff, use:
        import window.miff
To select an X window or an area of the screen with the mouse and save it in the Encapsulated PostScript format to include in another document, use:
        import figure.eps
To capture the entire X server screen in the JPEG image format in a file entitled root.jpeg, without using the mouse, use:
        import -window root root.jpeg
To capture the 512x256 area at the upper right corner of the X server screen in the PNG image format in a well-compressed file entitled corner.png, without using the mouse, use:
        import -window root -crop 512x256-0+0 -quality 90
               corner.png

Options
| Options are processed in command line order. Any option you specify on the command line remains in effect until it is explicitly changed by specifying the option again with a different effect. Import options can appear on the command line or in your X resources file. See X(1). Options on the command line supersede values specified in your X resources file. For a more detailed description of each option, see Options, above. ImageMagick(1).

Environment
| COLUMNS
| Output screen width. Used when formatting text for the screen. Many Unix systems keep this shell variable up to date, but it may need to be explicitly exported in order for ImageMagick to see it.
| DISPLAY
| X11 display ID (host, display number, and screen in the form hostname:display.screen).
| HOME
| Location of user's home directory. ImageMagick searches for configuration files in $HOME/.magick if the directory exists. See MAGICK_CODER_MODULE_PATH, MAGICK_CONFIGURE_PATH, and MAGICK_FILTER_MODULE_PATH if more flexibility is needed.
| MAGICK_CODER_MODULE_PATH
| Search path to use when searching for image format coder modules. This path allows the user to arbitrarily extend the image formats supported by ImageMagick by adding loadable modules to an arbitrary location rather than copying them into the ImageMagick installation directory. The formatting of the search path is similar to operating system search paths (i.e. colon delimited for Unix, and semi-colon delimited for Microsoft Windows). This user specified search path is used before trying the default search path.
| MAGICK_CONFIGURE_PATH
| Search path to use when searching for configuration (.mgk) files. The formatting of the search path is similar to operating system search paths (i.e. colon delimited for Unix, and semi-colon delimited for Microsoft Windows). This user specified search path is used before trying the default search path.
| MAGICK_DEBUG
| Debug options (see -debug for details)
| MAGICK_FILTER_MODULE_PATH
| Search path to use when searching for filter process modules (invoked via -process). This path allows the user to arbitrarily extend ImageMagick's image processing functionality by adding loadable modules to an arbitrary location rather than copying them into the ImageMagick installation directory. The formatting of the search path is similar to operating system search paths (i.e. colon delimited for Unix, and semi-colon delimited for Microsoft Windows). This user specified search path is used before trying the default search path.
| MAGICK_FONT_PATH
| Directory where ImageMagick should look for TrueType and Postscript Type1 font files if the font file is not found in the current directory. It is preferred to define the available fonts via type.mgk rather than use MAGICK_FONT_PATH.
| MAGICK_HOME
| Path to top of ImageMagick installation directory. Only observed by "uninstalled" builds of ImageMagick which do not have their location hard-coded or set by an installer.
| MAGICK_DISK_LIMIT
| Maximum amount of disk space allowed for use by the pixel cache.
| MAGICK_FILES_LIMIT
| Maximum number of open files.
| MAGICK_MAP_LIMIT
| Maximum size of a memory map.
| MAGICK_MEMORY_LIMIT
| Maximum amount of memory to allocate from the heap.
| MAGICK_TMPDIR
| Path to directory where ImageMagick should write temporary files. The default is to use the system default, or the location set by TMPDIR.
| TMPDIR
| For POSIX-compatible systems (Unix-compatible), the path to the directory where all applications should write temporary files. Overridden by MAGICK_TMPDIR if it is set.
| TMP or TEMP
| For Microsoft Windows, the path to the directory where applications should write temporary files. Overridden by MAGICK_TMPDIR if it is set.
