示例1: fromqimage

# 需要导入模块: from PySide.QtCore import QIODevice [as 别名]
# 或者: from PySide.QtCore.QIODevice import ReadWrite [as 别名]
def fromqimage(im):
    buffer = QBuffer()
    buffer.open(QIODevice.ReadWrite)
    # preserve alha channel with png
    # otherwise ppm is more friendly with Image.open
    if im.hasAlphaChannel():
        im.save(buffer, 'png')
    else:
        im.save(buffer, 'ppm')

    b = BytesIO()
    try:
        b.write(buffer.data())
    except TypeError:
        # workaround for Python 2
        b.write(str(buffer.data()))
    buffer.close()
    b.seek(0)

    return Image.open(b)
