[Qt-embedded-interest] How to display a QImage which is in Hex format

[Sujit Kumar]

Hi Trinath
    Use QByteArray *fromHex <qbytearray.html#fromHex>* ( const 
QByteArray & /hexEncoded/ )

QByteArray readCompressed = QByteArray:: fromHex (rStr.toAscii ()); 
if (readCompressed! = compressed) 
qDebug ( "bytes before hexing and dehexing _is_ different."); 
QByteArray readDecompressed = qUncompress (readCompressed); 
if (readDecompressed! = ba) 
qDebug ( "bytes before and after compressions are different."); 
QImage readImg; 
/ / QBuffer readBuf (& readDecompressed); 
readImg.loadFromData (readDecompressed); 
if (readImg.isNull ()) 
qDebug ( "The image is null. Something failed."); 
readImg.save ( "test.bmp");

Thanks,
Sujit
