How to use the Pixel Map Control QPixmap in PyQt5

This article mainly introduces PyQt5 how to use pixel image control QPixmap, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

The QPixmap pixel map control is one of the controls used to process images. It is used to display the optimized image on the screen. In our code example, we will use the QPixmap control to display the image on the program window.

#! / usr/bin/python3#-*-coding: utf-8-*-import sysfrom PyQt5.QtWidgets import QApplication, QWidget, QHBoxLayout QLabelfrom PyQt5.QtGui import QPixmapclass Example (QWidget): def _ _ init__ (self): super (). _ _ init__ () self.initUI () def initUI (self): hbox = QHBoxLayout (self) pixmap = QPixmap ('F:\ Python\ PyQt5\ Widgets\ images\ liutao.png') lb1 = QLabel (self) lb1.setPixmap (pixmap) hbox.addWidget (lb1) self.setLayout (hbox) self.move 300) self.setWindowTitle ('pixel map control') self.show () def showDate (self, date): self.lb1.setText (date.toString ()) if _ _ name__ ='_ main__': app = QApplication (sys.argv) ex = Example () sys.exit (app.exec_ ())

In our example, we display the image on the window of the program.

Pixmap = QPixmap ('F:\ Python\ PyQt5\ Widgets\ images\ liutao.png')

The QPixmap object we created requires a file as a parameter.

Lb1 = QLabel (self) lb1.setPixmap (pixmap)

The QLabel control to which we map the QPixmap object.

After the program is executed
