Does anyone know if it is possible to determine if an image is

library? I have been searching this news group and the information was
not all clear on this.

I have multi-page tiff files. I need to extract individual frames from the
multi-page tiffs and save them as single-page tiffs. 95% of the time I
receive multi-page tiffs containing 1 or more black and white CCITT4
compressed files (frames) inside the tiff. Every now and then I receive a
mixture of black and white CCITT4 and JPEG compressed files, and sometimes
just multi-page tiffs with JPEG only. The code runs great when dealing with

Hi
I've spent a good majority of my day trying to figure out how to have
PIL 1.1.5 working on my OSX 10.3.9_PPC machine. I'm still stuck and I
have not gotten anywhere. Could somebody please help me...
I've scoured all the documentation, google, and mailing lists to no
avail. I believe the problem may lay in a jpeglib problem with OSX
10.3.9, or a python paths problem.

Hi, everyone,
I am wondering whether it's possible to read part (e.g. 1000*1000) of
a huge jpeg file (e.g. 30000*30000) and save it to another jpeg file
by pure python. I failed to read the whole file and split it, because
it would cost 2GB memory.
Can anyone help me? Any comments would be appreciated.
Thanks.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
