maximum size for imagecreatetrue color()??

there seems to be a maximum size (in px) for images created with
imagecreatetrue color (somewhere between 4000 px and 4500 px). if the
image is bigger than that size, the browser doesn't display it but
reports errors in the image.

is this maximum size inbuilt into php?

or

does it depend on my server config and if yes how can i read it?

A full-colour 4096x4096 image occupies 48 MB (or 64 MB it it has an alpha
channel). My guess is this problem is not so much to do with a maximum image
size but rather the amount of memory allocated to the running of your
website. Either talk to your web hosts about getting it increased, or stop
using such enormous images.

yes, that occurred to me after posting. i had not thought about memory
at all, just followed the manuals recommendation to use
imagecreatetrue color() instead of imagecreate(), even if i don't really
need true color images. works fine now with imagecreate.

I am now using db2 v8.2 64bits without DPF. I want to create a very large table which is about 1000G and the record length is suitable for 32K page size. I find in the manual that the maximum size for 32K page size container is 512G only. Does it mean that the maximum size for 1 tablespace is also limited by 512G or I can create a tablespace with 2 containers (512G each) to support 1000G table? Thanks.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...
