嗨,我以为QMovie可以采用QBuffer?
这是我的代码。
a = QByteArray(img)
b = QBuffer(a)
self.movie = QMovie(b, 'GIF')
最佳答案
您要使用第二个构造函数:
QMovie::QMovie(QIODevice *device, const QByteArray &format = QByteArray(), QObject *parent = nullptr)
如您所见,第二个参数是一个QByteArray
,可以用字节替换,因此在下一部分中,我向您展示一个示例:
import sys
from PyQt5 import QtCore, QtGui, QtWidgets
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
# load data from
path = "congratulations.gif"
file = QtCore.QFile(path)
if not file.open(QtCore.QIODevice.ReadOnly):
sys.exit(-1)
ba = file.readAll()
buf = QtCore.QBuffer(ba)
if not buf.open(QtCore.QIODevice.ReadOnly):
sys.exit(-1)
movie = QtGui.QMovie(buf, b"gif")
w = QtWidgets.QLabel()
w.setMovie(movie)
movie.start()
w.show()
sys.exit(app.exec_())
