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:
gm 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:
gm 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:
gm 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:
gm import -window root -crop 512x256-0+0 -quality 90
corner.png

Options
|
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 GraphicsMagick 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. GraphicsMagick 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 GraphicsMagick by adding loadable modules to an arbitrary
location rather than copying them into the GraphicsMagick 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 GraphicsMagick's image processing functionality by adding loadable
modules to an arbitrary location rather than copying them into the
GraphicsMagick 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_HOME
|
| Path to top of GraphicsMagick installation directory. Only observed
by "uninstalled" builds of GraphicsMagick which do not have their location
hard-coded or set by an installer. |
|
MAGICK_LIMIT_DISK
|
| Maximum amount of disk space allowed for use by the pixel cache. |
|
MAGICK_LIMIT_FILES
|
| Maximum number of open files. |
|
MAGICK_LIMIT_MAP
|
| Maximum size of a memory map. |
|
MAGICK_LIMIT_MEMORY
|
| Maximum amount of memory to allocate from the heap. |
|
MAGICK_TMPDIR
|
| Path to directory where GraphicsMagick 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. |
