Kenji,

I see the same results on OS X 10.8.5 and Win 7.

I also tried a PNG with no colour management (i.e. no embedded colour profile) and the result was still different from Mac to Win, I also tried 2 different Macs with totally different monitor profiles so it's not a monitor profile having an effect, more likely a difference between the way LC handles colour management the two OSs.

I didn't see any discrepancy when I switched the image to a non colour managed JPG or a GIF, although the figures for the JPG were slightly different to the GIF. Colour managed JPEGs also exhibited the same sort of discrepancy.

Can you use a non colour managed JPG or a GIF file instead of a PNG in your project?

I do see this as an issue that really needs addressing. If you don't want to send in a bug report I would be happy to.

Paul
