Hello,

I am trying to build a workspace where PNG-images are processed into webmaptiles and then written to multiple sub-folders based on their zoom-level. However, I want the output result as a zip file which contains the folder-structure and can be written to a postgresql database. Does anyone know if there is a reader which does that? I don't seem to manage to keep the folder-structure when writing to a zip file using the PNG reader.

 

This job will anyway be published to a FME Server, so I have tried to upload it and run from there (with a PNG reader). I then get the correct sub-folder system from the data download url in a zip file, so that might be the way to go. I thought then of creating a second script that can call the result from the first script, but I am still very new to FME so not sure how that is done. Is there a reader which can call a result (url maybe?) from another fme server job?

 

Regards,

Anne

I use the ZipArchiver custom transformer from the FME Hub for this. Works within one workbench:

- Write temporary data (FeatureWriter).

- Wait till data is ready, use outputport summary feature to fetch data and zip it.

- Delete folder with temporary data (SystemCaller) with RM (remove directory).

Let me know if you need more help.


Agree that the ZipArchiver does the trick.

Alternatively, the TempPathnameCreator and the FeatureWriter (File Copy writer) could also be helpful.

Assuming that the attribute called "_folder" stores the path to the folder to be zipped. The output feature from the FeatureWriter will have an attribute called "_dataset", which stores the resulting zip file path.

Although I think the TempPathCreator isn't an easy one to start with it is a nice alternative for removing temporary files with a Systemcaller. Deep folder structures might give some problems as the temp path is quite deep itself.

Hi @nielsgerrits,

My goal is to do a datadownload service on FmeServer and to have in the result .zip this tree

- 1 pdf file

- 1 csv file

- 1 .zip file with 2 .shp fils in

I'm following your solution.

I use a FeatureWriter to create a folder with the 2 shp in $(FME_SHAREDRESOURCE_TEMP) -> OK

I use a ZipArchiver to fetch the folder and zip it in $(FME_SHAREDRESOURCE_TEMP) -> OK

But do you know how I can recover my .zip to write it in my final writer ?

Thank You

I think I have the solution with the writer filecopy.

@damien Excuses me for the delayed response, had some busy days. Did you work out a solution? You can use ZipArchivers or FileCopyWriters to write and collect the results to zip. I also use Emailers to send the response. If the file is to big for email (scan with the Directory an File reader) I copy it to a downloadlocation and let it be removed after 2 weeks.

Hi @nielsgerrits. No problem ! Yes, I've found a solution. I use a FeatureWriter and a filecopywriter (I didn't know this writer before my comment) and with the good parameters I have exactly what I want.

 

Thanks !
