#X text 49 38 the pix_film is the same as pix_movie but does not texture
the movie immediately onto a Geo.;
#X text 50 77 therefore it is possible to manipulate the frames;
#X text 48 106 the pix_film object will return the movie in it's (more
or less) native color-space. most of the times \, this will probably
be not RGBA but RGB or BGR (on windows machines).;
#X text 48 153 do not worry about this. however \, most of the pix-manips
will only work correctly on RGBA-pixes. if this is the case and you
send it a non-RGBA pixture it will say something like "pix_object cannot
handle gray image".;
#X text 49 226 to avoid this \, you can convert your pix-buff to RGBA
using "pix_rgba". this will be a no-cost operation if the pix_buf already
is in RGBA.;
#X text 36 334 you might notice a significant performance-enhancement
by just turning the [pix_rgba] off (via the toggle). however \, not
[pix_rgba] is expensive but actually the [pix_convolve] (which appears to do
nothing when initialized with "0 0 0 0 1 0 0 0 0". When [pix_rgba]
is "off" \, the [pix_convolve] will be bypassed \, and therefore be
very fast.;
