Will I be able to convert a HTML string to PDF using PDF Clown? Do you support HTML to PDF conversion now?
I’m pleased to confirm you that next version (2.0), which has been under heavy development since early 2021, will support HTML-to-PDF conversion (this feature will be fully integrated into its layout model to offer a seamless API experience). Version 2.0 is going to supersede the previous (unpublished) version 0.2.0, which had paused since 2016: the new version represents a full-order-of-magnitude advancement over the existing code base, completely renovating its functionalities yet keeping its core design principles; it will be modular to accommodate its sprawling set of features and will be Java-only (no more .NET). I will publish it as soon as possible, but I cannot be more specific at the moment, sorry.
Hi Stefano,
Thank you very much for your reply. Looking forward for your new release 😊
Can I edit PDF documents (i.e. search for some text and replace it with other text)?
Text replacement is a complex topic: PDF typically doesn’t flow, so it’s upon you to ensure the new text properly fits within the page; moreover, the characters referenced in your new text may have no mapping in their (probably) embedded font, as it may have been previously subset. Therefore text replacement is doable but somewhat difficult, depending on the actual characteristics of your files.
Can I use PDF Clown to generate PDF from HTML content? Particularly, can I make tabular structures?

I’m trying to make an Android note application with PDF Clown but having a hard time realizing its functions.
Can I use PDF Clown to render PDF file in my app which acts as a PDF reader?
At the moment (version 0.2.0) Android is not supported (PDF Clown relies on AWT).
Do you have any plan about handling images other than JPEG (XObjects where the stream is encoded with something different from DCTDecode)?
PNG and TIFF will be supported in the future (after 0.2.0 version).
Can I compress a file using PDF Clown for Java? Do you have an example to show? thanks
Yes, you can: please see the File compression sample.
