Chroma - a laser color blender

Well, it seems that it doesn't run on W7 x64. I found out last week. It works on 32-bit Vista and W7 for me though.

I will release a new version soon. I'm downloading Visual Studio 2008 now (legally I should add

).

It doesn't seem to work for me on Vista or W7 32 or 64 bit

Looking forward to the next revision of this fantastic tool

Thanx;

I had it running on Vista 64 bit but I couldn't get it working on W7 64 bit which was why I contacted Tocket. My research showed that there's a compatability problem between Matlab and W7 64 bit.

There should be no such problem on Vista 64 though as its a W7 problem.

An updated version is finished. Unfortunately, since I'm running W7 x64 with 64-bit MATLAB on this computer the new Chroma is 64-bit (and for no good reason).

The good news is that I've added a few new features. See the screenshot below and changelog for details.

Download link: http://blue.orgchem.kth.se/Chroma/distrib/x64/

Chroma v1.1 x64

This program will only run on 64-bit Windows!

Changelog:
Updated to MCR 7.11 - You need to install this version of MCR to run Chroma 1.1.
Added requested luminous power comparison.
Changed luminous flux to luminous power.
It is now possible to look at single wavelengths.
Minor GUI changes.
Command line interface has disappeared.

I just downloaded & installed Chroma (Win XP) for the first time...

WOW!
Awesome software, Tocket!
Thanks for sharing this with us!!

Interesting how clearly it shows the effectiveness of 640nm vs 660nm when it comes to "white balance" -

And how there's no way I'll be able to afford to balance my 400mw of 532.... $$$

I do like that extra edge I get in beams, however.....

I should add that I haven't actually tested the new version on a computer that does not have matlab installed, so I would appreciate if you let me know that it works. Remember to remove the old and install the new MCR.

32-bit users should still be OK with the old version. The new will not work for you until I can compile it on a 32-bit system, which I currently have no way of doing.

What do you need to compile a 32 bit version? I've got both 32 and 64 bit versions of W7, and both with VS2008...

Thanks Tocket, working fine here although it is very slow to initialise still.

@ Stuka, the best 1W balance I've found is 600mw 640nm, 300mw 532nm, 250mw 473nm. Works out to be 1.15 Watts and balance is dead centre perfect. Only improvement would be a little more blue.

**tocket** · 02-17-2010, 04:36

Yes, it is still slow to start and uses a lot of memory. That's the MCR... a bit like java. The only way to get rid of that is to port it to some other language. It might happen some day, but it's not a high priority.

Well, you also need MATLAB 32-bit.

**daedal** · 02-17-2010, 12:02

Yay! W7 64 with Chroma

Thank you

**bryce007** · 02-26-2010, 17:45

how did you get it to work? I also have W7 64-bit, and I tried all packages on the ftp, and it doesn't work

I recall having a problem with one thing... needing to move the file. I don't recall having any issues with the installation. Can you elaborate on the error you are getting?

--DDL

EDIT: I should probably mention that I moved it into a folder in 'Documents' that I created.

**bryce007** · 02-27-2010, 01:12

Ooops, I didn't have it in the same folder as the MCR. My bad!

**White-Light** · 03-28-2010, 18:10

Is your web down as its refusing to serve me - connection problems dialogue.

**tocket** · 03-29-2010, 04:27

Yes, the web server really is down. Making some changes to the computers at work (just got a Core i7 980X). I will have a (much slower) mirror up later today.

**tocket** · 03-29-2010, 09:27

Here's the mirror:
http://tocket.mine.nu/Chroma/

Only 10Mbit unfortunately.

Hi guys. I installed and updated a fresh legit copy of Win7 Pro 64-bit, installed .NET, the latest graphics card drivers, Matlab 7.11, changed the PATH and still when I click the Chroma x64 app the computer heistates as if it's about to launch and then... nothing. It doesn't launch, create any files or give an error message. It acts as if I never clicked on anything at all - nothing additional appears in the task manager during this process. I have tried installation in a different order many times, read and re-read this topic and Chroma readme with no luck. Matlab is installed in the proper location as described in the readme, too. Do any of you Windows 7 gurus know what might be the problem? Thanks in advance

**White-Light** · 09-04-2010, 04:12

It takes a long time to launch, typically around 30 seconds or so.

Maybe you're just not waiting long enough before cancelling the threads from task manager. If not then I'm not sure. I have it on Windows 7 64 bit and it runs fine on mine.

**motionloops** · 09-11-2010, 00:18

Thanks for your reply. It's really strange because I have the task manager open and never force close anything - when "launching" chroma nothing appears in the task manager at all. I've let it sit there overnight and still nothing. I'll get the "working" mouse pointer icon for a few seconds after double clicking chroma but that's it.

I bought and installed Windows7 on a new hard drive just for Chroma so I'm not giving up

I'll post exactly what I have and maybe someone will see something I've missed:

1. Install Win7 Pro 64bit
2. Install MATLAB 7.11 - resides in directory C:\Program Files\MATLAB\MATLAB Compiler runtime\v711
3. Add entry into the USER environment table as the variable "PATH" pointing to C:\Program Files\MATLAB\MATLAB Compiler Runtime\v711\runtime\win64
4. Place Chroma folder in Program Files.
5. Double Click Chroma

Anyone see anything wrong with this? Are there any special software updates or hardware requirements for Chroma with Matlab 7.11?

Thanks!
Ron

**Qumefox** · 09-12-2010, 00:18

You probably need to install microsoft visual c++ 2005 sp1 redistributable (x64)

That did the trick for me.

Check the event viewer. I bet it's complaining about VC80.MFC being missing every time you try to run chroma.

**kindmatt** · 04-14-2011, 08:26

I found this tool which lets you compile your MATLAB code as libraries or standalone executables so it can be used without needing to install 250MB of libraries.

It would be really helpful if you could compile your code using this tool to minimize the install size. Thanks for making an awesome application!
