Hello,
I use html2ps/pdf - as upgrade of FPDF - for conversion html/php pages to pdf.
It works great but I cannot solve the problem - how can I convert only part of the page without other CSS style. FPDF offers class CLIPPING.
However official html2ps/pdf forum doesn´t work properly and the documentation is very brief ...
Thank you for any sugestion. Petr
