I have tested iTextsharp and iText7 for HTML to PDF conversion. Based on the performance iTextsharp is taking 3 minutes for 10000 PDF creation. But iText7 taking 17 minutes for 10000 PDF creation. Since iText7 is new Version compared to iTextsharp,i decided to use iText7 for Commercial Purpose. But Performance wise iText7 is Low.So Please Tell me How to improve performance of HTML to PDF conversion in iText7?

I'm struggling with this problem for hours now but I can't find a way out, the problem is that: I wrote a program that generate a pdf file using itext version 7 (and a lot of it) along with some statistics, every things is right till here, but when my pdf should contain some arabic strings they just appear from left to right, no matter what I've tried (changing fonts, using universal encodings, making the string inside a cell of table, using canvas, ...)

We are trying to make the signed signature LTV enabled. I am using the below code to add verification. When signature.isTsp() is false, the PDF says Signature is not LTV enabled , though in the other case (signature.isTsp() is true) it shows as valid. When we open the PDF and try to manually add verification info by right clicking on the signature it enables LTV without any issue. Not sure what we are missing here. Any input will be highly helpful. // Adds LTV-enabled information to the PDF document. private ByteArrayOutputStream addLtv(final IOcspClient ocspClient, final ByteArrayOutputStream
