AW: AW: Is RGB on Mac something else as RGB on windows?
Hi Jaccque, in my case the result of a jpg and png screenshot is the same. On Mac I always have to add 30 to the charToNum(char x of tImageData) to get the same result as on Windows. I hope this really is a "constant" and not depending of any system or monitor settings, what could hit me on different customer machines.

Bill, I have no idea, but doesn't the unicode handling change come with 6.7?

Can you change your images to jpg? I've seen the problem with png images, and since I didn't need to match exact RGB, I only needed a visual match, changing the screengamma on a Mac was enough to fix it. I did this: on setScreenGamma if the platform = "macOS" then set the screengamma to 1.7 else set the screengamma to 2.23 end if end setScreenGamma -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Some more testing: The mousecolor returns the same RGB on Mac and Win. I need this for comparing each pixel of an imageData with this mousecolor. But when looping through the imageData of an image, the charToNum(char x of tImageData) returns a different value on Mac and Win. Up to now, it seems that the Mac value is always 30 less than on Win, same for R,G and B If this keeps constant on further testing, I can manipulate the values on Mac by this constant. But enough for today. Tiemo > -Ursprüngliche Nachricht- > Von: use-livecode [mailto:use-livecode-boun...@lists.runrev.com] Im Auftrag > von Tiemo Hollmann TB > Gesendet: Freitag, 12.

Hi Trevor, hmm, might be we are experiencing the same issue. The more I am testing, the more I get confused what happens with the RGB on Mac. Because I never would have thought that there could be an issue related to this between windows and Mac this issue hits me at the latest stage in my development process at the finishing tests close before release. Probably I have to suspend my whole release plan now.
