Changing Default Zoom Level For The Report HTML Output On JasperReports® Server

By default all reports use Template "Actual Size". This information could be checked by property "defaultTemplateUri" in file:

 /WEB-INF/applicationContext-adhoc.xml

More information about this property could be found in Admin Guide - section Ad Hoc Templates and Report Generators

For changing default zoom level (100%), for instance to 200%, it is necessary to add property "net.sf.jasperreports.viewer.zoom" with value 2 to "Actual Size" template in Jaspersoft® Studio:

Save this template and publish it to JasperReports® Server.

As result, all reports which will be created on JasperReports® Server with applied this template, will have zoom output level = 200%

For existing .jrxml reports the same result could be achieved by adding this property to the report level:

<property name="net.sf.jasperreports.viewer.zoom" value="2" />

There are other possible values for this property:

• integers (e.g. 3 for 300%)
• decimals (e.g. 0.75 for 75%)
• FitWidth
• ActualSize
• FitHeight
• FitPage
