[Qt-jambi-interest] Instantiating 'QImage(byte[], ..)' in a loop crashes the Java-VM

[Ralf.Weber at diehl-bgt-defence.de]

Hi,
I'm sorry, I think posted this in the wrong forum 'Qt labs forum -general
diskussions' before.

I'm experimenting with a tool to visualize raw image data (i.e 14bit grey
values)
using a QImage with 'Format_RGB32', following I convert the raw data to a
byty[]
array with 4 byte rgb data.
To support playback I instanziate the images with
      'image = new QImage(imgRgbBuf, 128, 128,
QImage.Format.Format_RGB32);'
in a loop and display the new image with 'painter.drawImage(0, 0, image);'
in the 'paintEvent()' slot (see 'ImgTest.java').
This crashes the Java-VM after a while.
Performace is no issue (..actually;-).
Using the 'image.loadFromData(imgRgbBuf, "Format_RGB32")' on the same
buffer as
above always returns 'false' and doesn't work.
How can I visualize raw rgb-data out of a buffer in mem. (in a loop) ?
Is it possible to work directly with int[] data ?


I strapped down a short example application in 'ImgTest.java'. (see
attachment)
Sorry, I'm neither a Java nor a Qt expert. Many thanks for your help in
advance,
it would be much appreciated.


Ralf
