How to construct Image from Bytes

[vishal.chauhan]

I do this aswell, but I had to put a QImageReader in between:

QByteArray array = qry.value(0).toByteArray();
QBuffer buffer(&array);
buffer.open( QIODevice::ReadOnly );
 
QImageReader reader(&buffer, "PNG");
QImage image = reader.read();

QByteArray array = qry.value(0).toByteArray();
QBuffer buffer(&array);
buffer.open( QIODevice::ReadOnly );
  
QImageReader reader(&buffer, "PNG");
QImage image = reader.read();

To copy to clipboard, switch view to plain text mode 

The code did not work unless I opened the buffer explicitly, so don't forget that.

Thanks for Reply.
But What is qry?and how to open buffer explicitly.
Also Is QImageReader reader(&buffer, "PNG") used to constuct a PNG Image or what?
If yes then If I donot know what type of Image is this then What Will I do?
