QImage to QPixmap Convertion Parameter Error after QT 6.2 Update at Python

[msaidbilgehan]

Python Version: 3.7
OS: Windows 10
QT Version: 6.2

I was using "QPixmap(qt_image)" to convert from QImage to QPixmap at QT5. After getting updates of QT6, I get error as below;

TypeError: QPixmap(): argument 1 has unexpected type 'QImage'

So changed usage of typecasting as QPixmap.fromImage(qt_image) and now getting this;

TypeError: fromImage(QImage, flags: Qt.ImageConversionFlag = Qt.AutoColor): argument 1 has unexpected type 'QImage'

There are some reference links that I used to get information about QT6 QPixmap;

• doc-snapshots.qt.io - QPixmap

Hi and welcome to devnet,

Do you have the same issue with fromImageInPlace ?

@SGaist

Hello and thanks, That is right.

QPixmap.fromImageInPlace(qt_image)
AttributeError: type object 'QPixmap' has no attribute 'fromImageInPlace'

I also converted all imports from qt6 to qt5 and there is no issue with typecasting using QPixmap(QImage).

But I should inform you, my QT APIs are PyQT, not PySide.

[SGaist]

Would you mind checking with PySide6 ?

From the looks of it, there's something wrong going on with PyQt.

@msaidbilgehan I just tested: qimage = QImage("/path/of/filaname") pixmap = QPixmap(qimage) on PySide6 and PyQt6 (the latest versions available) and it works fine. Could you provide a code that allows me to verify the error?

[msaidbilgehan]

@eyllanesc I am sorry but right now I can't. Downgraded from 6 to 5. I will wait for the best stable version of QT. Thanks a lot!

P.S.: I was using fromImage method which is necessary for my app flow. Not type conversion with the class call (such as QImage() )
