Title: About LGP files
Post by: Bert on 2010-06-09 19:53:20

Hi guys,
i'm new to this forum and i found a lot of very interesting discussions here (which brought me to register ;))

I had a question about an old LGP thread that i consulted:
http://forums.qhimm.com/index.php?topic=8641.0 (http://forums.qhimm.com/index.php?topic=8641.0)

I was wondering if and if yes how it is possible to use an LGP file (created with Highwind 1.21 program) in a C++ project.
And by using it i mean taking an image (address) and put it in a SDL_Surface for example.

Regards,
B.

You should post this is Tech related.

Why are you using Highwind?

He is talking about using highwind for LGP creation for something other then for use in FF7. So the 'use lgp/unlgp' may not apply here.

Good morning.
Sorry for not having posted my message in the correct section ! Thanks for the modification.

About the question, I am using highwind because i could add my own files (images/text files/etc.) so create a custom LGP archive.

The problem I am facing is that I don't know (in terms of C++ src code) how to get for instance 1 element of this archive and use it in a program.
I am using LGP because of the very performant compression it provides :)

Edit: I analyzed the lgp /unlgp source code but I doesn't seem that my answer is in there. Correct me if I mistake ;)

The LGP format doesn't provide any kind of compression at all.

I have to agree that it's very "performant" though, doing nothing is usually quite fast.

That's very interesting what you just said, and thanks for the help!
Knowing now that it's not a compression file but it regroups many of them, how du you access to one of them?
For instance, it doesn't work when you just search in the repertory LGP(file)/"resource name"

Do you need to open the file and then search the resource file using FILE functions (like in lgp.cpp and unlgp.cpp ) ?

Thanks for your help

Does anyone know how to use an image included in a LGP file in C++?
