CGAffineTransformInvert in Mac OS Qt 4.8.0

[markeshov]

Hi, please help!

When i'll try draw text on QPixmap or QImage by using QPainter, i'll get error: CGAffineTransformInvert: singular matrix.

there is code:

@ QRectF imgRect = QRectF(img->rect());

QPainter p(img);
p.setPen( m_conf.Color );
p.setBrush( Qt::SolidPattern );
p.setFont( m_conf.Font );
p.setOpacity( m_conf.Opacity );

qreal x = imgRect.width();
qreal y = imgRect.height();

qDebug() << p.transform();
p.save();
    p.translate( x, y );
    p.rotate(-90);
    p.drawText( QPointF(0 + m_conf.BottonMargin , 0 - m_conf.RigthMargin),m_conf.String);
    qDebug() << p.transform();
p.restore();@

on windows xp, 7 msvc++2010 this working good

Thanks
