NAME

       xcfview - display GIMP xcf files

SYNOPSIS

       xcfview [ options ] filename [ layer names ]

DESCRIPTION

       xcfview  is  a  wrapper script that uses xcf2png(1) or xcf2pnm(1) (q.v.) to flatten an XCF
       image and then displays the flattened image using a PNG or PPM  viewer  found  using  xdg-
       open(1) from the xdg-utils package.

OPTIONS

       Every  command-line  parameter to xcfview will be passed through to the underlying xcf2png
       or xcf2pnm command.  Because it is not certain which converter will be used,  the  options
       given should be ones that make sense for both of these.

       --mask  Enable the layer mask.

       --mode mode
               Set the layer mode (e.g., Normal or Multiply).

       --nomask
               Disable the layer mask.

       --opacity n
               Set the opacity on a scale from 0 to 255 (as used internally)

       --percent n
               Set the opacity on a scale from 0 to 100 (as in the Gimp user interface).

       -A, --force-alpha
               Invent a trivial alpha channel even if the flattened image is completely opaque.

       -b color, --background color
               Use  this  color  for  transparent pixels in the image.  The color can be given as
               #rrggbb or #rgb hexadecimal values, or as an X11 color name (which will only  work
               if a color name database can be found in one of a number of standard locations).

       -c, --color, --colour
               Force  the  output  to  use  RGB  color  space  even  if it there are more compact
               alternatives.

       -C, --autocrop
               Set the converted part of the image such that it just include  the  boundaries  of
               the  visible (or selected) layers.  This may make it either smaller or larger than
               the canvas, depending on the position and size of the visible layers.  (Note  that
               the contents of the layers is not taken into account when autocropping).

               In  the  absence of options that specify otherwise, the converted image will cover
               the entire XCF canvas.

       -D, --dissolve
               Do a "dissolve" step to eliminate partial transparency after flattening.  If -b is
               also given, this happens before the background color is applied.

       -f, --full-image
               First  flatten  the  entire  image  to a memory buffer before writing output. Then
               analyse the image to decide on the details of the output format (e.g.,  whether  a
               grayscale output is sufficient).  Without this option, the program flattens only a
               singe row of "tiles" (height 64) at a time.

       -g, --gray, --grey
               Force the output to be a grayscale image even if it may  be  monochrome.   If  any
               colored  pixels  are  encountered,  exit  with  status 103.  This will be selected
               automatically if the output file's name ends with .pgm.

       -G, --for-gif
               Assert that the flattened image will have no partial transparency (allowing a more
               compact  representation  of  the  alpha  output).   Exit  with  status  102 if the
               flattened image has any partial transparency.  If -b is  also  given,  this  tests
               whether there there is partial transparency before applying the background color.

       -h, --help
               Print an option summery to standard output and exit with a return code of 0.

       -j, --bzip
               Equivalent to -Z bzcat.  Default if the filename ends with bz2.

       -o filename, --output filename
               Write the converted picture to filename instead of to standard output.

       -O x,y, --offset x,y
               Offset the converted part of the image from the top-left corner of the XCF canvas.
               Usually used with -S.

       -S wxh, --size wxh
               Crop the converted image to width w and height h.

       -T, --truecolor
               Use standard RGB compositing for flattening indexed layers.  Without this  option,
               xcfview  will  mimic  the  Gimp's current strategy of rounding each alpha value to
               either full transparency or full opacity, and interpret all layer modes as Normal.

       -u, --utf8
               Use the raw UTF-8 representation from the XCF file to compare  and  display  layer
               names.   Ordinarily,  layer  names  will  be converted to the character set of the
               current locale.

       -v, --verbose
               Print progress messages about the conversion to standard error.

       -V, --version
               Print the version numer of xcftools to standard output and exit with a return code
               of 0.

       -z, --gzip
               Equivalent to -Z zcat.  Default if the filename ends with gz.

       -Z command, --unpack command
               Specify a command that the input file is filtered through before being interpreted
               as an XCF file. The command is invoked as command filename and must produce output
               to its standard output.  Note that it is not possible to specify arguments as part
               of command.  An uncompressor is selected automatically if the filename  ends  with
               gz  or  bz2;  to  suppress this, use -Z cat (which is implemented without actually
               starting a cat(1) process).

EXIT STATUS

       The exit status is 0 in case of success. A nonzero exit status may either be that  of  the
       xcf2foo converter or that of the image viewer.
