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 portion of the screen.



Image Settings: -adjoin join images into a single multi-image file -border include window border in the output image -channel type apply option to select image channels -colorspace type alternate image colorspace -comment string annotate image with comment -compress type type of pixel compression when writing the image -define format:option define one or more image format options -density geometry horizontal and vertical density of the image -depth value image depth -descend obtain image by descending window hierarchy -display server X server to contact -dispose method layer disposal method -dither method apply error diffusion to image -delay value display the next image after pausing -encipher filename convert plain pixels to cipher pixels -endian type endianness (MSB or LSB) of the image -encoding type text encoding type -format "string" output formatted image characteristics -frame include window manager frame -gravity direction which direction to gravitate towards -identify identify the format and characteristics of the image -interlace type None, Line, Plane, or Partition -interpolate method pixel color interpolation method -label string assign a label to an image -limit type value Area, Disk, Map, or Memory resource limit -monitor monitor progress -page geometry size and location of an image canvas -pause value seconds delay between snapshots -pointsize value font point size -quality value JPEG/MIFF/PNG compression level -quiet suppress all warning messages -regard-warnings pay attention to warning messages -sampling-factor geometry horizontal and vertical sampling factor -scene value image scene number -screen select image from root window -seed value seed a new sequence of pseudo-random numbers -set property value set an image property -silent operate silently, i.e. don't ring any bells -snaps value number of screen snapshots -support factor resize support: > 1.0 is blurry, < 1.0 is sharp -transparent-color color transparent color -treedepth value color tree depth -verbose print detailed information about the image -virtual-pixel method Constant, Edge, Mirror, or Tile -window id select window with this id or name Image Operators: -annotate geometry text annotate the image with text -colors value preferred number of colors in the image -crop geometry preferred size and location of the cropped image -geometry geometry preferred size or location of the image -help print program options -monochrome transform image to black and white -negate replace each pixel with its complementary color -repage geometry size and location of an image canvas -quantize colorspace reduce colors in this colorspace -resize geometry resize the image -rotate degrees apply Paeth rotation to the image -strip strip image of all profiles and comments -thumbnail geometry create a thumbnail of the image -transparent color make this color transparent within the image -trim trim image edges -type type image type Miscellaneous Options: -debug events display copious debugging information -help print program options -log format format of debugging information -list type print a list of supported option arguments -version print version information By default, 'file' is written in the MIFF image format. To specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for standard input or output.
