How to print/screenshot a tabwidget to an image file (.jpg/.png) in high resolution?

Piyush

Hi,

I am working on a piece of code wherein I have to print the tabwidget to an image file (.png/.jpg) file. The file is being created by the following code but i cannot view it.

Code:

    ```
    printer.PrinterMode(QtPrintSupport.QPrinter.HighResolution)
    printer.setOrientation(QtPrintSupport.QPrinter.Landscape)
    printer.setPaperSize(QtCore.QSizeF(297, 420), QtPrintSupport.QPrinter.Millimeter)

    temp_pdf = "abc.png"
    printer.setOutputFileName(temp_pdf)
    painter = QtGui.QPainter(printer)
    painter.drawPixmap(0, 10, self.ui.tabWidget.grab())
    painter.end()

Do you want to send the picture to a printer or why do you use QPrinter instead QPixmap::save()?

I was actually working with PDF before this after which the requirement changed to image file. I am open to using QPixmap but I don't know how? Could you please help me with an example?

tried Qpixmap.grabwidget but it seems to be deprecated in PyQt5.

hi
There is
http://doc.qt.io/qt-5/qwidget.html#render
which you can use to directly make tabwidget draw to pixmap.

@mrjj Can you share an example?

Hi
There is not so much to say about it.

// make bitmap that is size of widget
QPixmap pixmap(widget->size());
// ask widget to paint it self to the pixmap
widget->render(&pixmap);

@mrjj Thanks. It worked. Was a very simple and quick solution.

pixmap = QtGui.QPixmap(self.ui.tab_2.size())
self.ui.tab_2.render(pixmap)
pixmap.save('abc.jpg','jpg')
