I would suggest using "Report An Issue" located at the top of this website.
More on the original post: Posted that I did not make any changes to the FM files before generating a report and exporting to pdf. Apparently must have made one change: if in containers actual files are embedded, rather than references to files, Results in very large differences in pdf file size. Embedding files in containers seems to always results in smaller pdf files, 5.5 MB, references seems to always results in larger file sizes, 65 MB file size.
In iOS it is even better, same report results in 1.5 MB pdf file size.
Is it the same exact file in the container field in each case?
Different image files inserted into the same field may not have the same resolution and thus one PDF could be quite different from another given the difference in the size of that inserted file.
Yes, no changes are made to the files in the containers. The difference is embedding Vs. reference. Embedding results in much smaller pdf file size than when containers use reference to files. Embedding all files into containers, and exporting to pdf gives me 5.5 MB file. Referencing files into containers, and exporting to pdf gives me 65 MB files. With iOS and files embedded into containers results in the smallest pdf file, 1.5 MB.
iOS seems to use a different version, resolution, and encoding software. So it seems that when exporting to pdf, if reports have containers, it is best to first embed files into containers.
