Projects / RenRot


Renrot renames files according the flexible name template (allowing DateTimeOriginal and FileModifyDate EXIF tags, if they exist; otherwise, the name will be set according to the current timestamp). It can aggregate files according to shooting time period. It can losslessly rotate JPEGs and their thumbnails according to the Orientation EXIF tag or a given angle. It can put commentary into the Commentary and UserComment tags. Personal details can be specified via XMP tags defined in a configuration file.

    Release Notes: When verbosity level set to zero, the program is now a lot less informative when it dies. All messages which are not related to the "info" or "process" category will be put to the standard error stream.

    •  15 Sep 2008 14:47

      Release Notes: The option --aggr-virtual-directory was removed, and you should use --aggr-directory instead. Now the "#" (hash) symbol can be used at the beginning of a given color value in a command line. The tree for an aggregation is created automatically. Documentation has been updated accordingly.

      •  05 Sep 2008 06:08

        Release Notes: Serveral bugs were fixed in the aggregation framework. The hardcoded path separator symbols are removed. This should bring proper path interpretation on non-Unix operating systems. The virtual aggregation now also works for delta aggregation mode. The documentation has been updated in accordance with the last changes. A small optimization was done in the contact sheet generator.

        •  26 Aug 2008 15:42

          Release Notes: Thumbnail generation has been added. Aggregation can be performed with an absolute path now, but on the same file system. A thumbnail image for the contact sheet generator can now be in any format supported by ImageMagick. The plain documentation was expanded, especially for the contact sheet generator. The sample directory has been created with the dotrank and dotkeywords files. A few bugs were fixed. The --no-ren-rot-tag-mtm option was renamed to --no-renrot.

            Release Notes: A major upgrade was done. The contact sheet generator has been implemented. This new feature requires the Image::Magick Perl module at run-time. In addition to the contact sheet generator framework, the rank functionality has been added. See the applied manual to get details for using it. The configuration parameter "use color" is turned off by default.

            Very useful
            This is a very useful util. Just if it could recursively process files

            in several subdirectories .. :)
