The perfect white balance - feedback requested

[tocket]

Working for me although it doesn't appear in programmes list or as an icon - you have to find it where you downloaded it. I moved my copy to the desktop.

2 pieces of feedback:

1. It would be useful to have a clear button for the luminance map as once you've tried 2 or 3 different mixes it becomes very hard to know which is which and you need to restart the program to clear the map.

2. It would be useful if it would zoom to full screen as the colour gradients on the map are quite hard to view at current size.

Thanks for your comments. Regarding the first point; the plot is actually cleared between every refresh in the code. Obviously this doesn't work, so it's in fact a bug. I'll take another look at the code, but I suspect I will either have to add some ugly code or rewrite the callback function.

As for your second point, the gradient is not very accurate, but I can see how a zoom could be beneficial at times. I'll see if it's easy to add such a feature.

I got the new version to work on my old opteron 175 running XP. Thanks!

For point 1, couldn't you just reinitialize the graph each time "update" is pressed?

[tocket]

I have a solution to the plot clearing problem, somewhat ugly... but it works and is very simple (single line of code). As I see it there are three options for implementing it:

1. Clear every time update is pressed.
2. Add a clear button and don't clear when update is pressed.
3. Add a check box and clear on update when it is checked.

So what do you think is best?

Hey, whatever is simplest for you.

For me Option 1 seems best but like Allthatwhichis said, what ever is easiest for you Tocket.

Its a great little programme and much appreciated. I'm sure its going to make laser power choice a lot easier for everyone.

New version uploaded. I went with option 3, as I find it is sometimes useful to not clear the graph when adding new points (comparing 2 different setups).

I can unfortunately not find a way to add zoom functionality. I did make one small other change now though; the window is slightly larger.

The next change is probably making the gradient more accurate.

I can't run the new version Tocket.

I'm getting the original error message despite having Matlab installed.

Funny... I wouldn't put it past me to have uploaded the wrong file again, but this seems to be the correct one. I recompiled it and it seems to work on all of my 3 computers now. I did not make any changes to the code, but instead found that crossing your fingers and standing on one leg while pushing the compile button is more likely to produce a working executable. The console window will spit out a couple of hundred warnings when it starts now instead, but it works fine. That even happens to me in matlab sometimes, for no apparent reason.

Anyway, a new "working" version has been uploaded.

Still can't get it to run.

If a re-instate the original file from out of the recycle bin, the original chroma runs, albeit it takes like 20 seconds to initialise (I have a very fast pc - C2D 6600+ Overclocked + 4GB RAM + RAID Array) so this is strange in itself.

If I delete the original chroma to recycle then try to install the latest Croma I get the original .dll can't be found error.

Could it be something to do with the package associating itself with the original file?

[tocket]

What's the size of the file you're trying to run? Or better yet, the MD5 checksum? It should be:
38b6d7bb2f07b7aa0e3df803919bf06d Chroma.exe
7ec36aec97fc2d67961a597fe2514d53 Chroma_pkg.exe

I found that my browser cached the old version, so when I thought I was downloading a new version I was in fact just running the old again.

It does take a while to start the program, because it has to load MCR.

EDIT: nevermind, tried it on a fourth computer, and it doesn't work. This is stupid... I'll take another look at it when I get home, but it must be some bug with the compiler.
