Display GIMP xcf files.
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 alterna‐ tives. -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 ana‐ lyse 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 auto‐ matically 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 flat‐ tened 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 cur‐ rent 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.
