This documents the Job Request File format that third-party systems can create integrate with a Color Factory server. It also includes the specs of the PRF (Process Results file) that Color Factory returns to allow the other system to pick up the output file and determine whether the processing succeeded.
About Job request files
The Job Request File (JRF) is an ascii file that contains the full local or UNC (Universal Naming Convention) path for an image file that is to be processed by Color Factory. It also contains the full path of the resulting output file.
The moment a JRF is saved in a Color Factory hotfolder it is read and the processing starts. This means that the file to be processed must be in place before the JRF is created.The output file will be given a temporary name during the processing and renamed to the proper name when the output file is complete. If a file with the same name already exists it will be overwritten. The input and output filenames can be the same.
Process result files
Color Factory can generate a result file that will contain the name of the output file and an error code with description.
The result file will have the same name and path as the JRF but with the extension PRF (Process Result File).
The JRF file is always removed by Color Factory.
The syntax of the files is the same as a Windows “INI” file. This will give us the possibility to extend the functionality at a later stage.
A JRF is recognized by Color Factory as such if the file begins with the string “[JRF]”.
