photocat is a simple java application for producing (digital) quasi 'contact sheets'. A contact sheet is a print-media page of thumbnails representing a set of photographic images. Essentially you provide a number of images and it produces a PDF containing pages of those images scaled down together with some meta-data.
An example of where this might be useful is in the archiving of photographs. For example, an organization keeps photographs of each project and after the project has completed, they archive those photos away. A contact sheet would then be a reference where they could, at a glance and in a relatively smaller PDF file, see what was stored into each archive.

To build this software, you will need the following;
- An internet connection
- Java 17
- Apache Maven
To build;
mvn clean && mvn package
The software can be run either from the command line or as a desktop application. In either case, the same conceptual settings are used
This is the directory containing the images and movies that should appear in the contact sheet.
This is the file where the output PDF will be written
This is the optional output of an intermediate XML file. This XML file is a necessary resource for developing your own contact sheet format should you wish to.
This is the binary for ffmpeg which is used to create stills for movies that may be included in the source image / movie directory. ffmpeg can be downloaded from here. If you do not install ffmpeg then movies' stills will not appear properly in the contact sheet.
You can use this option to either use the simple built-in template or you can nominate your own template should you have created your own one.
This will define the maximum size of the images that are included in the contact sheet. The larger this value is, the larger the contact sheet PDF file will be and the more memory will be required to produce the output PDF.
To launch the software using a command line interface issue a command like this, correcting the actual path to the jar file depending on your situation;
java -jar .../photocat-contactsheet-cli/target/photocat-contactsheet-cli-...jar
Running the software with no options will provide you with a list of options.
To launch the software using a graphical user interface, issue a command line like that shown below, correcting the actual path to the jar file depending on your situation;
java -jar ..../photocat-contactsheet-desktop/target/photocat-contactsheet-desktop-...jar
If you want to make your own contact sheet template, this is possible. Use the "XML Output File" option and produce an example XML file from your data. Now you can create an XSLT file that produces FO (formatting objects) output. Internally, the FO is run through the FOP tool to produce the PDF.
There is a command-line tool provided with FOP to process the XML file with your XSLT file and then process the resultant FO into FOP. This can help with developing your XSLT file.
The default XSL file exists within the sources for this project.
