Re: Merging two gif images in JDK 1.1.8 using AWT

I write some *applets* that are intended to
wrap or support other applets. They need
to be 1.1 compatible to do what they need
to do (which is usually catch the last 1.1,
1.2 & 1.3 VMs and warn the user they need
to upgrade) and are thus very simple, and
sandboxed.
If I wanted to catch a 'huge audience' for
a desktop support API I would aim it at
1.3+ to include the last Mac OS9 installations
(Though I was surprised to hear in the last
two months, of a developer who specifically
needed to support OS9).
In general my support APIs are targeted at
1.4+, while the end-user applications are
either 1.5+ or (more and more) 1.6+.
For this app. that you are discussing to be
'1.1 compatible', it would either need to be
a trusted applet (assuming it does something
useful like save the altered image) or a stand
alone app.
I very much doubt that the last users of
1.1 would know how to launch an application
using 1.1. Did 1.1 implementations recognize
the main-class attribute of manifests?
So, I echo Lew's incredulity that it makes
sense to target 1.1+.
For image manipulation, I would probably go
for 1.4+, to get to the ImageIO class.
As for the 1.1-1.3 VM/Boxes. Forget them,
they probably have difficulty connecting to
the internet, let alone doing useful image
manipulation (without a lot of extra code).
