imshow interpolation='bilinear' equivalen in pyqtgraph

[Agus]

Dear experts,

 

I usually use matplotlib with imshow and  interpolation='bilinear' method  to display my image looks smoother.

Does pyqtgraph have something like this?

I don't know if it's exactly the same, but the ImageItem has a setAutoDownsample() method (and an 'autoDownSample' keyword argument that you can use in setImage() or the constructor) that might be similar enough for your purposes...

I should have said, it does the downsampling by averaging nearby pixels. Looks like the size of the neighborhood depends on the amount by which the image is downsized.
