Database BLOB to Image in Qml

[sandro4912]

So I have an SQL Database which contains an Picture stored as a BLOB.

What is the easiest way to show it in an Image in QML ?

I already can expose the data to QML as QByteArray but how to load that in an Image?

You can try the technique described here.

Hi,

What about a custom image provider ?

[sandro4912]

@SGaist Can I provide to that one If I get the data in QML as QByteArray? I expose a struct with other data aswell to QML and one contains the QByteArray.

I followed the instructions in the link you provided and it worked well.

I just don't understand how you would came up with passing

"data:image/png;base64,"

to Image. I think that should be in the docs of Image.

That is the way to fully embed an image in a web page without the need for a remote file but it makes the size of the data at least twice as big.
