示例1: fromqimage

# 需要导入模块: from PySide import QtCore [as 别名]
# 或者: from PySide.QtCore import QBuffer [as 别名]

    """
    :param im: A PIL Image object, or a file name
    (given either as Python string or a PyQt string object)
    """
    buffer = QBuffer()
    buffer.open(QIODevice.ReadWrite)
    # preserve alha channel with png
    # otherwise ppm is more friendly with Image.open
