Re: [Interest] Error : QImage: out of memory,

[Igor Mironchik]

Hi,

You get this error in slot onImageReceived()?

or you are talking about this lines:

QImage img(cdata, 288, 352, QImage::Format_RGB888);
    img = img.scaled(QSize(288*1.5,352*1.5));
    delete[] cdata;

Hello,

I've a function as follows. With this I get QImage: out of memory,
returning null image, I dont allocate heap to QImage anywhere.
but the crash happens at QImage img(cdata, 288, 352,
QImage::Format_RGB888). Any clue.
If the QImage is allocating the memory to the heap internally how to free that?



void AddToQueue(/*param*/)
{

    /*
..
    */

     QImage ampl_image = convertImageWithImageAdjust(/*param*/);
     QImage dist_image = convertImageWithImageAdjust(/*param*/);
     emit imageReceived(ampl_image, dist_image, FPS);

}

QImage convertImageWithImageAdjust(/*param*/)
{
   /*

..

   */
     QImage img(cdata, 288, 352, QImage::Format_RGB888);
     img = img.scaled(QSize(288*1.5,352*1.5));
     delete[] cdata;
     return img;
}


void GestureCamCorder::onImageReceived(const QImage &amplImage, const
QImage &distImage)
{
     QPixmap tempImage = QPixmap::fromImage(amplImage);
     ui->amplImage->setPixmap(tempImage);

}
