Hey folks!

I'm in need of a bit of help using the ZipStream module.
What I want to be able to do, is load an image from a .zip file, but I can't
seem to get it to work. I'm probably doing something dumb, so here's a the
code and a download.

 Framework brl.system
  Import maxgui.Drivers
  Import brl.Bmploader
  Import brl.Pngloader
  Import brl.Jpgloader
  Import brl.EventQueue 
  Import brl.Event 
  Import brl.Basic
  Import koriolis.bufferedstream
  Import koriolis.zipstream
  Import brl.Max2d


Local imageo:TImage=LoadImage("zip::Foldo.zip//1.png")

DrawImage imageo,10,10

WaitKey 

End

In the same folder as the code, I have a zipped folder named Foldo, which
contains the image 1 within it. If nothing is wrong with my code, then I probably
need to reinstall MinGW, lol.

Your are trying to draw an image without Graphics().
In the zip to download there is a folder "Foldo".
So you need "zip::Foldo.zip//Foldo/1.png"
Why is your zip's filename .zip.zip?
Very confusing.

This code works, when the zip is name "Foldo.zip"
and the 1.png is in the folder "Foldo"

'Framework brl.system
''  Import maxgui.Drivers
'  Import brl.Bmploader
'  Import brl.Pngloader
'  Import brl.Jpgloader
'  Import brl.EventQueue 
'  Import brl.Event 
'  Import brl.Basic
 Import koriolis.bufferedstream
  Import koriolis.zipstream
'  Import brl.Max2d

Graphics 800, 600

Local imageo:TImage = LoadImage ("zip::Foldo.zip//Foldo/1.png")
If imageo = Null Then Throw("no such image")
DrawImage imageo, 10, 10
Flip
WaitKey

End

lol, woops!

Can't believe I forgot to include 'graphics' ;)

Half of programming seems to be acting like a dumb a**.

Works fine now!

Thanks a bundle Volker!

Now I'm having a bit of difficulty getting SetZipStreamPassword to work, lol.
I want to read from a compressed, password protected file, but am not sure how
to use SetZipStreamPassword. I know what it's suppose to do, just not how
to use it correctly.

Would anyone mind giving me a quick example?

Thanks,

Volker

A simple
'SetZipStreamPassword("Yourpath\Foldo.zip", "yourpassword")'
before accessing the zipfile should do it.

I tried that ;(

Didn't seem to be working.

I'll give it another shot in a bit.

Thanks a bundle Volker!

It took me awhile to get your demo working, but I finally realized what I was doing
wrong.

I was doing this.
SetZipStreamPassword("zip::Foldo.zip", "password")

Instead of doing this,
SetZipStreamPassword("Foldo.zip", "password")

It's always the dumb stuff that gets you ;)

Thanks again Volker, you really made my day helping me finally get this working.
I now have my graphics folder zipped up tight, with a rather nifty password, and I
even changed the extension from .zip, to .TurkeyFeet so you'll need a custom program
to even look inside the folder :D

Hi Werdna,

I was doing this.
SetZipStreamPassword("zip::Foldo.zip", "password")

I did the same the first time :-).
