Hi group,
I'm confused, kind of. The application I'm writing currently reads data
from a FITS file and should display it on a gtk window. So far I have:
[...]
pb = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, False, 8, width, height)
pb_pixels = pb.get_pixels_array()
print(type(fits_pixels))
print(type(pb_pixels))
which gives
<type 'numpy.ndarray'>
<type 'array'>
So now I want to copy the fits_pixels -> pb_pixels. Doing
pb_pixels = fits_pixels
works and is insanely fast, however the picture looks all screwed-up
(looks like a RGB picture of unititialized memory, huge chunks of 0s
interleaved with lots of white noise).
Doing the loop:
for x in range(width):
for y in range(height):
pb_pixels[y, x] = fits_pixels[y, x]
works as expected, but is horribly slow (around 3 seconds for a 640x480
picture).
So now I've been trying to somehow convert the array in a fast manner,
but just couldn't do it. What exactly is "array" anyways? I know
"array.array", but that's something completely different, right? Does
anyone have hints on how to go do this?
Kind regards,
Johannes
