Hi

I was trying to compress an pdf file
Here is my code:

Document doc = new Document
(new FileInputStream("./data/Example.pdf"));
OptimizationOptions opt = new OptimizationOptions();

opt.setCompressImages(true);
opt.setImageQuality(1);
doc.optimizeResources(opt);
doc.save("./output/output.pdf");

And I got an Exception

Exception in thread “main” java.lang.IllegalArgumentException: Map size (0)
must be >= 1
