dynamic image creation with original ASP

[Guru]

One of our systems creates an image with an ID on it.
It creates an xbm image.

This works fine except the c***s at Micro$soft have decided not to suport xbm in IE on XP SP2

Therefore, I need to create a gif or jpeg

I don't want to use extra DLLs if possible and ASP .NET is not an option.

I know there is a registry fix which will allow the browser to display xbm files but that is not an option either.


Any suggestions?


Thanks

Um, dunno if there's code out there for this (not looked into it) but can you not just add the other dll (the one you don't want to) onto the server so it converts the xbm image into a gif/jpeg... Would be easier to implement?

In a word.. NO!

[vbNeo]

WEll then, write a converter yourself, there really is no other option the way I see it...

[Guru]

Which part off "no additional DLLs" doesn't anyone understand?

[davebat]

Dont ask for help and say that the only way its possible is out of the question.

Okay then smartass, don't post on this forum, non of us is obviously able to help you - I, however, am surprised that his excellency was not capable of figuring this out himself.

Whoops, made the small text big and the big text small, how clumsy of me

I've got it 75% sussed now.

I can now store a gif as a hex string and write it out from within an asp page - without any additional DLLs.

I just need to suss out how to write uncompressed gifs

[davebat]

The best way would be to use a DLL to do this

[Guru]

The best way isn't always possible in the real world

[Wokawidget]

Guru, you are not going about this the right way.
It's clear that the answer to your solution is what people have been suggesting.
I'd advice you not to get so irate when people are only trying to help.

People here have given up their own time to try and help you, and then you flame them...Hmmmm...will they help you in the future....I think not.

Why are you unable to use a DLL, for curiositys sake?

Is that an easy thing to do?

Politics.

Deploying DLLs on a customer's server is more trouble than it's worth. There would also be licencing implications for third-party components

I believe it is possible - originally devised to get round paying Unysis royalties for use of the LZW (?) compression algorythem.

[Ecniv]

Not sure if any of these will give you a hand (you've probably been there already)

Thanks Ecniv

I will check it out a bit later when I've got some time to spare.

I found a perl script last night which appears to do what I want; I just need to convert it to vbscript or javascript.
