Export the plot image to memory

[Saurabh Sarkar]

Hi -

I am trying to export the plot image to memory instead of a file in disk. Some what similar to matplotlib:

             buf = io.BytesIO()

             fig.savefig(buf,format = 'png')

             buf.seek(0)

or to an array :

            img_d = np.fromstring(fig.canvas.tostring_rgb(), dtype=np.uint8, sep='')

            img_d = img_d.reshape(fig.canvas.get_width_height()[::-1] + (3,))

Is there an equivalent approach in pyqtgraph?
