Can I set ZOOM_RATIO for reports created by REST or Web Service?

[mschraudolph]

I´m accessing a JasperServer from my PHP-App using REST.

The rendered reports in HTML format are very small.

Googling the problem showed, there is a parameter ZOOM_RATIO, that can be set via Java by something like

parameters.put(JRHtmlExporterParameter.ZOOM_RATIO, 1.5F);

I dont know anything about the "Java way" of accessing JS so i have no clue, where/how to set this parameter when accessing JS the way I do. Can this export param be set inside the report itself or by using a magic parameter when rendering via REST...?

Thanks in advance
