I have tested the points in barn that should have colour (143, 91, 33) and found colour values that are very close. The list of (pixel, colour) is [((887, 1096), (142, 91, 38)), ((2226, 1397), (141, 92, 34)), ((2007, 1402), (141, 91, 40)), ((2161, 1508), (142, 91, 34)), ((1187, 1702), (141, 91, 40))]. I think you will need to change the images to PNG so we all see the same colour values.

Could it be different JPEG decompression libraries? If so, perhaps you could convert the images on GIT to a lossless format like PNG.

a few more ideas.

Ok. I'm stumped. I will try

I added im.convert('RGB') with same result. Python 2.7.10, Ubuntu Linux 64 bit. Can you verify that my code above (with convert) returns the expected colour on your machine?

I am still having problem replicating your result. My code: def findpixels(fname): im = Image.open(fname+'.jpg'); px = im.load(); print 'TEST', px[(887, 1096)] using barn prints (142, 91, 38). Could you specify the origin (top left?) you are using? Maybe using 1-based rather than 0-based indexing?

For the barn image, I get a pixel list of [(612, 1131), (690, 1155), (784, 1065), (888, 1106), (900, 1729), (903, 1099), (980, 1498), (1581, 1420), (1661, 1529), (1811, 1484), (2140, 1650)] for the (143, 91, 33) colour value. At least one of our programs has an error.

The barn.jpg image is 2600x1733 pixels yet you provide an (x,y) list [(1096,887),(1397,2226),(1402,2007),(1508,2161),(1702,1187)] that includes y values larger than 1733. Am I misunderstanding these lists?

I will run the code and find where I went wrong.

Wow. I did not know ideone exists.

Keeping with that example, is your result 34 vs 37 or 34 vs 42 strength?

I don't use Java so I cannot run your code, but thanks.

Hi. I am thinking about what you have wrote. Hmmm.

No problem.

Thanks. I will need to edit my code anyway. That -1 bandit will catch me otherwise.

The underscores would be easier.

Ok. The -1 bandit owner has confused my line parser as the hyphen is both a delimiter and minus sign on this line. I will fix it. Thanks for debugging help.

Aha. The trailing semicolon and hyphen on the first line will cause the error. If you intended these characters to be there, I can change my code.

I checked the code again. This is the error that it will throw if one or more of the fields are empty eg: 0_0_600_5_15_10_12_10_7_5_1_40_---. Any chance the error is on your end?
