There are 4 ways to view Images in PyQt5.
First way: QLabel, QPixmap
label = QLabel(self)
pixmap = QtGui.QPixmap("landscape.jpg")
label.setPixmap(pixmap)
label.setGeometry(500,300,650,493)
Second way: QPainter, drawImage
painter = QPainter(self)
target = QRect(500,300,650,493)
source = QRect(0,0,650,493)
image = QImage("landscape.jpg")
painter.drawImage(target,image,source)
Third way: QPainter, drawPicture (however, this gives me an 'Incorrect header' error)
painter = QPainter(self)
picture = QPicture()
picture.load("landscape.jpg")
painter.drawPicture(0,0,picture)
Fourth way: QPainter, drawPixmap
painter = QPainter(self)
target = QRect(500,300,650,493)
source = QRect(0,0,650,493)
pixmap = QPixmap("landscape.jpg")
painter.drawPixmap(target,pixmap,source)
This leaves me very puzzled and very very confused. Which of these ways should I use to get the highest quality of Images and geometric figures both on video and in print?
