Theresult of this variable is not important, the key is currentbook which returned the result is undefined. I want this currentbook value equals pdf's PageHeight.

Well, it can work.

var curFileStats = new FileStatistics(job.getPath());

currentbook = curFileStats.getNumber("PageWidth");


I tried, but without success.

Can you give me an example of flow?







test.sflow

var re ="5454564";

var s=Switch;

s.log(1,"variable = " + re);



TypeError. Undefined member function 'log' for object '[object FactoryObject]' of type: 'FactoryObject'

how to use function FileStatistics?

var curFileStats = new FileStatistics(re);

currentbook = curFileStats.getNumber("PageWidth");
