In this Qt6 video we are going to learn about How to Draw Image with Qt6, for this purpose we want to use QPainter class with QImage, so Qt6 QPainter is 2D painting system in the Qt6 framework, which provides a way to render graphical elements such as lines, curves and shapes in to different surface types including widgets, images and printers.
It is powerful and flexible tool for creating custom graphical interfaces and visualizations, and also supports different painting operations including basic drawing primitives such as lines, arcs and rectangles, image manipulation, gradients and transformations. and QImage provides platform independent representation of an image and can be used to read, write and manipulate image data. you can create QImage object from file, buffer of raw image data or by specifying the image dimensions and format. with QImage, you can perform different image operations including scaling, rotating, flipping, cropping and converting between different image formats. you can also draw images in to QPainter object or display them in a Qt6 widget.
