Build 3.5.0.48 of xlsgen ensures that vector shapes in PDF files are made of native and scalable objects.
Before this build, vector shapes were drawn in a bitmap and then inserted in the PDF file, which would make it larger in size, and vector shapes not adapt the zoom level.
Now vector shapes being rendered as native PDF objects (lines, curves, text glyphs, ...), they take a lot less space in the PDF files and they do scale according to your zoom level.
This build follows the previous one related to text boxes.
And this works both for floating vector shapes and vector shapes in charts.
