[PYTHON IMAGE-SIG] Imaging
Sun, 23 Jun 1996 17:28:32 -0400 (EDT)
So, I finally got back to working on my live Indycam stuff (working
towards a page with real-time image grabbing from the camera, with
images never getting saved to disk, as opposed to a cron job which
consumes resources all the time).
The camera can handle upwards of 30 fps. no problem, but the realtime
raw to (some format) conversion is a pain!
For my quickcam solution on my Linux PC, I was able to hack up something
without much hassle because I hardcoded myself a 64-greyscale palette
and hacked the hell out of someone else's code (giflib-2.2) to the point
where I couldn't reproduce it even if I wanted to..
For the Indycam, I got the python module to the point at which I could
GET the raw image, and left it there.
Now that I have PIL, I have a chance of getting this thing where I
want it! Today I got a page going which snaps the image and does the
conversion to jpeg, and spits it out.
You can give it a try (until the server dies or I kill it) at:
Compare it with the (faster, but black&white) original Dave-cam at:
This whole process of taking one image and converting it to a jpeg takes
a bit over 2 seconds which leaves plenty to be desired as far as "real-time"!
Converting to gif is even slower (about 4 seconds) because it uses the pbm
stuff to do it with...
My question is, is there going to be native gif-writing support anytime
soon, or do I have to^H^H^H^H^H^H^Hget to write it myself?
