Hi , i have signed with CADES signature some pdf file and convert them to p7m file e.g. test.pdf to test.p7m.
For anyone don't know the p7m extension it's just like a zip file where you can extract the single file in it, by using a specific key.
What i want it's to extract the original pdf in the p7m and make it visualize on share like a normal pdf on runtime while using share, so i can use the standard preview and standard thumbnail of the orginal pdf file.
NOTE: by some expert suggestion on a similar question , i need to setup a composite / pipeline transformer for P7M to PNG, since there is likely not going to be an existing one that works with PDF as an intermediary.
In the documentation of alfresco 5.2 the png not support the preview so instead, i'm tring to use the tiff format to show the original signed document of the p7m file (pdf or text o what else).
So in the end i'm tring to make a trasnformer P7M to TIFF:

That would be a nice addon to have on github
03-31-2021 04:47 AM
Hi, I'm an Italian user who uses dockerized Alfresco Community 6.2. The p7m format is typically used in Italy for the signature of pdf files and being able to access the content in order to index it is absolutely a priority.
I have inspected the "n" dockers that have been created to manage the environment but I can't find where to put the various files you propose in your solution.
For example: "/ src / main / java / org / alfresco / transformers /" I can't find it (especially the "transformers" folder)
Anyone know if there is an addon on github?
Thank you, see you soon!
Andrew

@andrea65 The transformer construct used as the basis for those Docker images is significantly different from the old in-process transformers. None of the files can be re-used as-is to build a Docker-based transformer. A general description of how new transformers are implemented can be found in the ACS Packaging project.
