Re: [Matplotlib-users] plotting large images

You could look at whether or not you actually need 64-bit precision. Often 
times, 8-bit precision per color channel is justifiable, even in grayscale. 
My advice is to play with the dtype of your array or, as you mentioned, 
resample.

thanks, this helped me significantly,  uint8 precision is enough.

Also, is it needed to keep all images? It sounds to me like your application
will become very resource hungry if you're going to be displaying several of
these 2D images over each other (and if you don't use transparency, you won'
t get any benefit at all from plotting them together).

Yes, I need them all .

To avoid it I am thinking about merging them into one image and then plot 
it.
