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
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).
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.
