Sorry if this get¹s re-posted, my earlier e-mail didn¹t seem to go through.
I have an array of images stored as an array of numpy arrays. I need to be
able to efficiently scroll through that set of images. My first attempt at
doing this goes something like this:
--init--
self.ax = pyplot.imshow(imgdta[0], interpolation='spline36',
cmap=cm.gray, picker=True) # draw the plot @UndefinedVariable
pyplot.axes().set_axis_off()
self.fig = self.ax.get_figure()
self.canvas = FigureCanvasGTKAgg(self.fig)
--onscroll--
self.ax.set_array(imdta[n]) # 0 < n < num_images
self.canvas.draw()
This method ends up re-interpolating the image on each scroll event (which
takes SIGNIFICANT time). What I¹d like to do is pre-build the images and
then just change what image is displayed on the canvas on each scroll event.
I cannot seem to figure out how to do this. Can anybody give me a pointer
in the right direction.
Thanks,
Dave.
