Include a new tab in Preferences - Advanced.
This provides the possibility to use an external preview image decoder
or extractor.
Usage is described in the Help file.

+ <title>External preview extraction</title>\r
+ <para>\r
+ The intention of this feature is to give the user the possibility to display image previews of files\r
+ that the standard libraries cannot decode.\r
+ <para />\r
+ An example is the .dng files produced by LG V30 cameras. Neither\r
+ <code>exiv2</code>\r
+ nor\r
+ <code>libraw</code>\r
+ can\r
+ extract a preview, but the command line program\r
+ <code>dcraw</code>\r
+ can.\r
+ <para />\r
+ This feature allows a work-around until the standard libraries provide a solution.\r
+ <para />\r
+ Two command files are required: one to identify which files to process, and one to extract or decode the preview image.\r
+ <para />\r
+ The format for the identification tool is:\r
+ <para />\r
+ <pre>\r
+ <programlisting xml:space="preserve">\r
+ Parameter 1: (input) full path name to the current image.\r
+ <para />\r
+ Returns: 0 for file match, any other value for no match.\r
+ </programlisting>\r
+ </pre>\r
+ <para />\r
+ The format for the extraction tool is:\r
+ <para />\r
+ <pre>\r
+ <programlisting xml:space="preserve">\r
+ Parameter 1: (input) full path name to the current image.\r
+ <para />\r
+ Parameter 2: (output) a temporary file name generated by Geeqie. The tool should load this file with the decoded image.\r
+ <para />\r
+ Returns: not used.\r
+ </programlisting>\r
+ </pre>\r
+ <para />\r
+ This is an example of an identification tool using a shell script:\r
+ <para />\r
+ <pre>\r
+ <programlisting xml:space="preserve">#! /bin/bash\r
+\r
+ filename=$(basename -- "$1")\r
+ extension="${filename##*.}"\r
+\r
+ shopt -s nocasematch\r
+ if [[ $extension == "DNG" ]]\r
+ then\r
+ cameramodel=$(exiv2 -K Exif.Image.UniqueCameraModel -Pt "$1" )\r
+ if [[ $cameramodel == "LG-H930" ]]\r
+ then\r
+ exit 0\r
+ else\r
+ exit 1\r
+ fi\r
+ else\r
+ exit 1\r
+ fi</programlisting>\r
+ </pre>\r
+ </para>\r
+ <para>\r
+ This is an example of an extraction/decode tool using a shell script:\r
+ <pre>\r
+ <programlisting xml:space="preserve">#! /bin/bash\r
+ dcraw -e -c "$1" > "$2"</programlisting>\r
+ </pre>\r
+ <para />\r
+ Alternatively:\r
+ <pre>\r
+ <programlisting xml:space="preserve">#! /bin/bash\r
+ gm convert "$1" "$2"</programlisting>\r
+ </pre>\r
+ </para>\r
+ <para>\r
+ If the decode tool requires an output file with a particular extension, use this method:\r
+ <pre>\r
+ <programlisting xml:space="preserve">#! /bin/bash\r
+ tmpfile=$(mktemp --tmpdir=$tempdir geeqie_tmp_XXXXXX.jpg)\r
+ gm convert "$1" $tmpfile\r
+ mv $tmpfile "$2"</programlisting>\r
+ </pre>\r
