Display a colored image with pixels stored as numpy array


#1

Hello,

I would like to display a colored disc, with every pixel’s RGB values specified in a numpy array. I can generate the image as a 3D numpy array (n rows of pixel x n columns of pixels x 3 colors RGB), but I can’t find a way to display it.

The closest thread I could find is the following, but it’s not exactly what I’d like to have in my stimulus.

May I ask if ImageStim or GratingStim can do this? If so , how do I pass the pixel array to the object?

Thanks,
Alan

You can pass the array as the image argument to ImageStim or the tex argument to GratingStim.

Thanks! It works now with ImageStim. I was stuck before as I didn’t know the size argument is necessary for ImageStim.
