  • What is the difference between QImage and QPixmap?
    QPixmap is an "image object" whose pixel representation are of no consequence in your code, Thus QPixmap is designed and optimized for rendering images on display screen, it is stored on the XServer when using X11, thus drawing QPixmap on XWindow is much faster than drawing QImages, as the data is already on the server, and ready to use
  • xlib - What is the difference between XYPixmap, ZPixmap, XImage . . .
    From the X11 protocol specification: The data for a pixmap is said to be in XY format if it is organized as a set of bitmaps representing individual bit planes, with the planes appearing from most-significant to least-significant in bit order
  • Python - matplotlib - PyQT: plot to QPixmap - Stack Overflow
    from PySide6 QtGui import QImage, QPixmap from matplotlib backends backend_agg import FigureCanvasAgg as FigureCanvas from matplotlib figure import Figure def get_q_pixmap(): fig = Figure() canvas = FigureCanvas(fig) ax = fig add_subplot(111) ax plot([1, 2, 4, 3]) ax set_title('test plot') canvas draw() width, height = fig figbbox width, fig
  • qt - How to use QPainter on QPixmap - Stack Overflow
    When you add a pixmap to a scene using addPixmap, only the current pixmap is used Further changes will not affect the scene So you should call addPixmap after you make changes Also you need to destroy QPainter before you use the pixmap to ensure that all changes will be written to the pixmap and to avoid memory leak
  • qt - How to change size of QPixmap? - Stack Overflow
    I am write a paint program pix = QPixmap(600,500); set size to 600X500 How to change size after this? Someting like: pix setSize(800,600); Change size to 800
  • qt - QPixmap and SVG - Stack Overflow
    How would you suggest to handle svg with QPixmap? The construct QPixmap(": myfile svg"); then call of scaled() does not work The QPixmap gets pixelised Thx
  • Programatically setting the pixmap of a QLabel in Qt
    The Widget we should use to show pictures is a QLabel we can do it directly from QtCreator, by setting its pixmap property we should first create a resource file and then add the image to that resource file To create a Qt Resource File, we go to the menus: File > Qt > Qt Resource File we can set the image of the QLabel using Qt Creator
