Servoy JasperReports Plugin

HI Andrei,

yes the slow scrolling is the same in versus 4.x of the plugin.
We indeed use background image, (letter logo A4).

If we remove this image, scrolling is fine & quick! :-)
How / where do I set this property??

Hi Harjo,

I think you can just add it to your report, nested after the <jasperReport...> element, like this:
<jasperReports...>
<property name="net.sf.jasperreports.viewer.render.buffer.max.size" value="2M"/>
..

If that does not work, you can try using ireport, like described here: http://community.jaspersoft.com/wiki/properties-how-use-additional-properties-build-enhanced-reports.

Hope this helps. (sorry for the late reply, I have some problem with getting case updates from ServoyForge :) will fix it ).

Me too, I don't receive notifications also,
will try it monday morning!

Hi Andrei,

i added the line by hand (see attach)
also the property is shown in ireport under the report properties.
But unfortunately it does not work!. Scrolling with the mouse (with an A4 image logo in the background) is terrible slow in the viewer.

Hi Harjo,
Can you try to set the value of that property to something like: 10000000000 :).
Let me know if this works (better).

Hi Andrei,

this time I got a mail notification of your reply! so that's good! :-)
I'm just back from external work. Tommorow I'm back at the office and will try your suggestion, and will keep you updated!

HI Andrei, I just changed the line in my report to: <property name="net.sf.jasperreports.viewer.render.buffer.max.size" value="10000000000"/>

but no change, scrolling with an image background is still VERY slow. If I scroll once, it scrolls 15 * 1px to the bottom, and every 1px takes about a second! so in total, 15 seconds.

Hi Harjo,

I am not sure what to say in this case; maybe when we go to a newer version of the jasperreports engine, this will be improved. Therefore, please keep an eye on https://www.servoyforge.net/issues/780. It's in progress currently :-). When this is ready, we'll try a test with that.

Regards,
Andrei

did you already tested the slow scrolling (with image background) with the new version??
