QImage copy

[paolom]

Hi,

I have a QImage with an existing uchar * buffer.

If I make:

qimage = qimage.scaled(..);

qimage = qimage.scaled(..);

To copy to clipboard, switch view to plain text mode 

the qimage buffer is the same, or I need to delete the previous buffer ?

thanks

QImage::scaled() makes a deep copy of the image. The new image will have its own (new) buffer.

Yes, but the new buffer of the scaled image, it is managed by the qimage or I need to delete it after the image destruction?

[wysota]

It is managed by QImage instance.

you need not delete it manually.
