Jasperreport remove vertical space inside frames - jasper-reports

Question

I have a jasperreport and I am trying to reduce the vertical size of its two frames. As you can see in this screenshot
The 3 frames (the surrounding frame and the two internal frames) are larger than the contents.
I have been struggling to reduce their size to the size of the contents but without success. Any ideas what I can do? The par1 = null, par2=2, par3=3, par4=4.
My jasperreport:

Edit:
I tried to reduce the size of the frames and set their removeLineWhenBlank property to true, and now everything disappears if I set the values par1=par2=null, par3=3, par4=4. Why ? I only want to remove the lines that are blank, not all of them:

Answer 1

what is the format that you are generating your reports. Lets assume you are generating reports in HTML format and the following trick will do the job.
<property name ="net.sf.jasperreports.export.html.using.images.to.align" value="false"/>
Hope that helps .
