jasper report height

I am creating a jasper report. The default size of the report is A4. I want to change the report's height dynamically. I am using HTML Export.So it is creating a html for A4 size(Even though content size is half of the A4 size). If the report content size is small, I want the html page size also small.

Is it possible to achieve开发者_运维知识库?

Try setting the contents Position type to Float in the elements properties.
