Maintaining Aspect Ratio of Image in Qt

[rohitkk]

Dear All,

Is there any way for maintaining the aspect ratio for the Image being taken from the db.
What exactly I am doing is I am populating db with the image (the datatype for the image is BLOB in DB) & later on I am displaying that image on the reports.

The code I have used for displaying the Image on the reports is below,

QPainter *reportPainter;
QPixmap p;
QByteArray myImage;
p.loadFromData(myImage);                      //myImage = Acquired from the db
p.scaled(120,60,Qt::KeepAspectRatio);       //This is not required as x & y co-ordinates are fix
reportPainter->drawImage(QRect(60,0,120,60),p.toImage());              //Adding image in QPainter with rectangle size kept fixed.

QPainter *reportPainter;
QPixmap p;
QByteArray myImage;
p.loadFromData(myImage);                      //myImage = Acquired from the db
p.scaled(120,60,Qt::KeepAspectRatio);       //This is not required as x & y co-ordinates are fix
reportPainter->drawImage(QRect(60,0,120,60),p.toImage());              //Adding image in QPainter with rectangle size kept fixed.

To copy to clipboard, switch view to plain text mode 

In Line of Code no. 4 : Image is scaled to fix width & height (viz. not the requirement, as it should be calculated based on the acquired image height & width)
In Line of Code no. 5 : Similarly, the Image is drawn in the fix rectangle.

How to get the image's height & width present in the db? or Is there any other way to do so?
And yes I want to maintain the aspect ratio of the image in the report acquired from the database.

Thanks in Advance.
