使用PySide将QImage转换为Numpy数组 [英] QImage to Numpy Array using PySide

问题描述

我目前正在从PyQt切换到PySide.

I am currently switching from PyQt to PySide.

使用PyQt，我使用在

With PyQt I converted QImage to a Numpy.Array using this code that I found on SO:

def convertQImageToMat(incomingImage):
    '''  Converts a QImage into an opencv MAT format  '''

    incomingImage = incomingImage.convertToFormat(4)

    width = incomingImage.width()
    height = incomingImage.height()

    ptr = incomingImage.bits()
    ptr.setsize(incomingImage.byteCount())
    arr = np.array(ptr).reshape(height, width, 4)  #  Copies the data
    return arr

但是ptr.setsize(incomingImage.byteCount())不适用于PySide，因为这是

However ptr.setsize(incomingImage.byteCount()) does not work with PySide as this is part of the void* support of PyQt.

我的问题是:如何使用PySide将QImage转换为Numpy.Array.

My Question is: How can I convert a QImage to a Numpy.Array using PySide.

Version Info
> Windows 7 (64Bit)
> Python 2.7
> PySide Version 1.2.1
> Qt Version 4.8.5

推荐答案

PySide似乎没有提供bits方法.如何使用 constBits 获取指向数组的指针?

PySide doesn't seem to offer a bits method. How about using constBits to get the pointer to the array?
