The goal of this DLL is to combine multiple compressors into one DLL.

This is only the first version so it only supports .gz .bz and .zip for now.

The user is responsible to give credit and use the licenses of zlib (http://www.zlib.net/) and libbzip2 (http://www.bzip.org).

Example screen shot:

The functionality per format:

GZIP:
Threaded
Compress/Decompress
Get percentage completed
Get speed in bytes-per-second
Get size completed
Get elapsed time

BZIP:
Threaded
Compress/Decompress
Get percentage completed
Get speed in bytes-per-second
Get size completed
Get elapsed time

ZIP:
Threaded
Decompress
Get list of files in ZIP file
Get compressed/uncompressed size of found file
Get CRC32 of found file
Get comment of ZIP file
Get percentage completed
Get speed in bytes-per-second
Get size completed
Get elapsed time

.gz = http://www.zlib.net
.bz = http://www.bzip.org
.zip = don't have to credit

Is that correct understood?

When you use the DLL for no matter what you always have to credit both.
The libs are always used in the dll.

cool dll man B) but currently I don't have a use for this

[ChIkEn AtE mY dOnUtS]

Yay, my request was done!

Thanks man

[Meiun]

Awesome work man! Your gonna be the best DLL producer on the GMC (in my mind atleast) if you keep this up. Finally a good compression DLL other than gm7zip ^^

Hey, I've just swapped too your compression library and have found myself at a bit of a problem. I know how to check if something is finished de/compressing and continue, but I don't know how to wait until it's finished then do a specific action.

Could you help me out please?

Also with GZ_GetReady() it is a little confusing, just to clear my mind, are the following the same basically;

if (GZ_GetCompleted()=100){}
if (GZ_GetReady()=1){}

Thanks for reading.

When GZ_GetReady () returns 1 it's ready, that works the best.

[ben_dover]

Ok thanks for that. Could you help me a little further please? What I'm trying to do is zip a file that contains a hell of a lot of game data and send it from a server app to client's then have them decompress it and read. I just don't know how to write it properly.

clearbuffer()
writebyte(99);
GZ_Compress("save.f1", "farmsave", 9);
saveFile=fileopen("save.f1", 2);
fileSize=filesize(saveFile);
fileread(saveFile, fileSize);
with(obj_client)
{
if(id=player)
{
sendmessage(clientsocket);
}
}
fileclose(saveFile);
file_delete("farmsave");

But this does not work because the compression does not have enough time to finish. So how exactly do I program:
if compression is finsihed send file, if not then wait until it is finished then send file.

Thanks for your time mate.

[uuf6429]

in step event:
if GZ_GetReady()=1
{
// finished
}

[ben_dover]

Ok thanks uuf6429, that took alot of work to implement in, I have to use a 2nd object now to handle the compression. (The original object was compressing in a step event (depending on the circumstances, it was a networking object).

h0bbel I got to the point where I almost went back to your older compression, where gzip and zlib were separate. But then I worked out my problem, I had forgot to initialise the DLL in my server program. It works great, 88kbytes of integers and |'s down to 4.57.

Cheers!

[uuf6429]

@ ben_dover - Glad it worked for you.
@ h0bbel - Glad this dll exists, I was trying my own from ground up. Yours is the best solution! Keep the good work.

Any plans to add .zip compression?

[acrog2]

Is there functionality to make it compress a whole directory/folder? I could use some help.

[shredded.carrot]

I am having trouble with it decompressing files. With the example I understand it probably only needs say one more line but what do I add?

Never mind I worked it out for myself

Decompressing is not working for me. I used WinRar to make the Zip but I don't think that should make a difference. Ok I've got this to load and extract the zip.

[codebox]UZ_Open (area);
UZ_ExtractFile("INFORMATION.di2",working_directory+string(global.gem_path)+"\INFORMATION.di2")
UZ_ExtractFile("AUDIO.mp3",working_directory+string(global.gem_path)+"\AUDIO.mp3")
UZ_ExtractFile("lighting.ls",working_directory+string(global.gem_path)+"\lighting.ls")
UZ_ExtractFile("GEMS.di2",working_directory+string(global.gem_path)+"\GEMS.di2")[/codebox]

Area is a variable that contains the path to the zip file btw. But when all that is executed, nothing happens. I've got this to let me know when it's done:

[codebox]draw_set_halign(fa_center)
draw_set_color(c_white)
draw_text(room_width/2,160,"Installing Song...")
draw_set_color(c_black)
draw_set_halign(fa_left)
draw_text(5,5,"Elapsed Time: " + string(time))
draw_healthbar(16,room_height/2,room_width-20,room_height/2+10,UZ_GetCompleted (),c_black,c_red,c_aqua,0,true,true)
[/codebox]

Absolutely nothing happens! I've included the DLL also. I've got no idea what else to do.

Wish you would fix the mass amount of bugs in your downloader =/.
Any chance this may gain support for 7z or arc?

Hello!

I want to extract multiple files with the DLL, but have problems, as most files after unpacking 0 bytes. Can someone help me?

Create:

AC_Init();
global.meldung1 = "Download wird entpackt!";
UZ_Open(global.update);
File = UZ_FindFirstFile(); // First File
UZ_ExtractFile(File,File); // Extract first File

entpacken = true; // Exctract true

Step:

if entpacken = true {
if (File!=""){
        File = UZ_FindNextFile ();
        if (File!="")
        UZ_ExtractFile(File,File);
    }
}else{
    entpacken = false;
    alarm[1] = 30;
}
