Porting Violet to Java

Doug, as I wrote above ... implement .HDR instead. I'll ask Ian if I might
share the partially code of radium with you, then you just have to copy
the stuff and plug it in jViolet. If you're interested I'll dispatch a mail to
Ian in a second and will get back to you as soon as possible.

take care

Leave it a while psor. There's still plenty work to do just to make it useable with IGIs.
Extending to other formats can come later.

Ok, as you wish!

Just as a quick note. I quickly checked the latest code of sunflow that's
available per svn, ... and they already have the .exr and .hdr stuff
included. So if you're interested, or anyone else, ... take a look there.
So there is no need to bug Ian.

nb: They also have the IGI read/write stuff in there.

take care

hmm, ok if it's already been done I may have a quick look at how they did it.
If I have to start from scratch, it'll have to wait a while.

Thanx Doug!

Hang on a sec... why do you want to save the LDR output from Violet into HDR formats?
This doesn't make much sense.

On the other hand I can understand full reading HDR and EXR files.
Sunflow has sources for reading HDR only, I'll have a look at that first.

Okay, after anoying power problems my api work on the gui was lost, but not a big deal the hard part i had a backup up

Currently trying to reslove one anoying conflict as svn wont let me commit till im done, but any way here is what it looks like (Metal l&f dosent line up right due to diffrent fonts, but it sucks anyway so im not so concerned)

Everything in the GUI should be responsive and change when you play with it, but its not connected to anything (again, lost my api work)

You might not have been able to commit due to my server being down this afternoon after a powercut.
Strange we both had power problems today

Anyway, the GUI looks good

I've done yet more refactoring I'm afraid - trying to move away from the slightly dis-organised c++ file layout and make the Java packages more logical.
If you can't manage to commit or resolve conflicts etc, you can attach or PM me your sources and I'll merge it by hand.

Are you able to fix the histogram-problem, I found earlier?

The one, that gets visible, if you resize the window

First attempt at loading an HDR image, using a class from sunflow:

Almost there... I'm reading the data in the right order at least, just a problem with scaling or number format or something.

psor, you got it ... Radiance HDR loading

BTW, eman:
I'm going to stop committing revisions now until we've got your GUI in place. Sorry if my obsessive updates make it hard for you.

Okay, your commiting help me a lot, i had files from 3 different commits and didnt know it!

Its now up there still w/o the api as i was trying to get the damn thing to comit. Im actualy going to write a file listener that can do what psor was asking casue i think i can

also, make sure the sunflow's license will let you barrow their code.
