Compression/Decompression Question

DriakTravo · Post by **DriakTravo** » Sun Oct 12, 2003 7:35 pm

Is there any way in Purebasic that you can compress many files into one and use it in a purebasic program. Example: if I wanted to compress 5 sprite bitmaps and 2 wav sound files into one file and use it in a game.

I give many thanks to any help.

Have you looked at PureInstall ??

You could also IncludeBinary your files and then UPX your compiled app.

Hmmm... Thanks! That will prove to be very usefull to me!

What I meant tho was put 5 bmp and 2 wav into one file and use the file in PureBasic.

I think the best solution is to compress each file you need (a .bmp , a .wav , etc.. ) with PackMemory() and then you include each compressed file in your program with IncludeBinary. At run-time you decompress each file. Instead of using IncludeBinary, you could add the compressed files as resources. That would be better since you won't waste memory. See in the Tips&Tricks section how to load a file from resources.

You could use the packer stuff...

Don't ask me how though. I've never tried them.

I tried using the packer but I couldn't get it to work. I guess im just not that good yet.

Mabe one day someone will teach me

easy! 'binary include' your media into your exe, then download UPX.exe, lob it in your windows folder, then on the command line from a CMD prompt, type 'UPX --best APPNAME.exe'.

Easy!

The packer lib is here for that: you create the pak file, add some file with AddPackFile() and then use the CatchSound()/CatchSprite() commands when reading it back. If you need more info, tell me..

Yep,
you create your pak file:

createpack("mycompressedfiles.pak")

; you add your files

addpackfile("Image1.bmp")
addpackfile("Image2.bmp")
addpackfile("mywave1.wav")
addpackfile("mywave2.wav")

closepack()

you execute this code to compress the files.. After in your program:

openpack("mycompressedfiles.pak")

catchsprite(0,nextpackfile())
catchsprite(1,nextpackfile())
catchsound(0,nextpackfile())
catchsound(1,nextpackfile())

closepack()

It's ready to use...
