hi everybody.
is there a possibilty to have the output of a render as a jpg file?
because in the message window of povray it says "LibJPEG 6b, Copyright
1998 Thomas G. Lane"... i didn't find a commandline-switch or something
to change the output to jpg, but if it's not possible, why mention the
JPEG-llibrary?
an alternative would be a program i can use in a batchfile to convert
files from bmp to jpg, if possible with low quality loss, like acdsee
does. i need this because i want to make an animation with 1500 frames,
but at 640x480 this would need 900kb per picture, resulting in almost
1.5GB of files. this would not be a problem if i were rendering on my
own pc, but i have to do it on another machine to which i have only slow
access via wlan.
thanks for listening to me, and if this is the wrong newsgroup, please
point me to the right one.
bye
Marc

i'll try this one

i'm not familiar with this format, i thought it was equally uncompressed

i don't think that makes sense, as the connection is not only slow but
also rather buggy, too many frames would get lost... ATM i'm simply
copying the .pov file to the remote machine if i have to render
something big, start up povray, wait, and when it finishes i take some
hours to copy the resulting pictures to my pc

I'll throw in my recommendation for netpbm as well. It's a little odd to
learn at first until it snaps in your head how they designed it, but it is
the ultimate conversion utility and it handles damn near every image format
you'll ever see -- and you can make uber MPEG-1 movies with it too. It's
like POV-Ray -- you /can/ find software with fancy interfaces, but you'll
never get the true feeling of power that netpbm will give you (arggh, arggh,
arggh, more power!)

PNG uses lossless compression. The reduction in file size is less than
with lossy formats like JPEG, but you get a perfect reproduction of the
image. It makes a good replacement for GIF, having better compression,
supporting 48 bit color, alpha channels, and file gamma values. It's
also good for archiving images or other situations where you want to
keep full quality.

A WLAN is reliable as any other network as far as deliverly of data is
concerned, it is just slow. Nothing can get lost or be buggy just because
it is used over a WLAN.

Are there any other lossy formats than JPEG? ;)

I just invented one: All files compressed with my format are 0 bytes in
size, and when the image is read, its dimensions and colors are guessed.
I expect this to be in widespread use before long.

trust me, i have to use it every day... the problem is, that the walls
in our house are to thick for it to work properly... i made a check via
the ping utility over a week about 20% of the pings didn't arrive
but i do agree that it *should* be as reliable as any other network in a
more common situation ;)

Marc
