Problems exporting graphs from GUI

[Alejandro Condori]

Hi, i was trying to export a graph from a QGraphicsView (promoted to PlotWidget with pyqtgraph as header file) but I had some troubles doing that. Spyder returns this error:

 

TypeError: 'float' object cannot be interpreted as an integer

So, I found the file where the problem was and made a change in line 70 of the file "ImageExporte.py" located in this directory: C:\ProgramData\Anaconda3\Lib\site-packages\pyqtgraph\exporters :

line 70 before:  bg = np.empty((self.params['width'], self.params['height'], 4), dtype=np.ubyte)

line 70 after:     bg = np.empty((int(self.params['width']), int(self.params['height']), 4), dtype=np.ubyte)

And the problem was solved, I didn't know where do I have to report this, so i posted this here

Hi Alejandro!

In my opinion, since you have found how to solve the issue, you can initiate the change to PyQtGraph's Github code repository by creating a pull request here:

https://github.com/pyqtgraph/pyqtgraph/pulls 

There are links on the page which help contributors posting a pull request for the first time.
