NAME

       xcfinfo - display information about GIMP xcf files

SYNOPSIS

       xcfinfo [ options ] filename

DESCRIPTION

       xcfinfo	is a command-line tool that displays information about the contents of image files in the XCF format used by gimp(1), particularly
       about the layers in the image.

OPTIONS

       -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.

       -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 com-
	       mand filename and must produce output to its standard output.  Note that it is not possible to specify arguments as  part  of  com-
	       mand.  An uncompressor is selected automatically if the filename ends with gz or bz2; to suppress this, use -Z cat (which is imple-
	       mented without actually starting a cat(1) process).

OUTPUT

       Information about the image is displayed on standard output in a fixed format.  The first line contains general information about  the  XCF
       file:

       -  The file format version

       -  The canvas size

       -  The image mode (color, grayscale, or indexed)

       -  The numer of layers

       -  The internal compression algorithm

       Following this line there is a line for each layer:

       1) The character + if the layer is visible and - if it is not

       2) The size and offset of the layer

       3) The pixel format of the layer, including whether the layer has an alpha channel.

       4) The layer mode, as well as the opacity if not 100%, and /mask if the layer has an active layer mask.

       5) The name of the layer.

EXIT STATUS

       The exit status of xcfinfo is

       0    Success

       20   Problems parsing the command line.

       21   The specified XCF file does not exist or cannot be read.

       123  The  XCF file contains presumably valid features that xcftools does not support.  (As of this writing there is no known way of getting
	    the Gimp to write an XCF file that will provoke this return. Please notify the author if you discover one).

       125  The XCF file is malformed.

       126  An uncompression program could not be executed, or terminated abnormally.

       127  Unexpected I/O error, internal errors, or other "this can't happen" situations.

       If an uncompression program returns an error exit status, this will be returned from xcfinfo too.
