Thanks Sean. I finally had time to check your file and indeed it
displays correctly in 8.1.6.
It still displays wrong in 7.1.3, but it displays differently than the
file without profile, so this must be the profile issue that was fixed
in 8.1.3.
In other words, my problem is with the way jpe
Hi Robert
I have looked at this and it is reacting this way because a correct
CMYK colorspace profile has not been embedded into the jpeg file.
LiveCode, therefore, has no idea how to interpret the colors and
handles them in an almost raw state oversaturating them. Adding the
closest profile to it
I just tested this in LC 8.1.6 and it shows the same problem as 7.1.3. I
filed a bug report for the team to check into this, including the files.
Bug 20316.

I am using 7.1.3. This is what I meant that this was a known problem.
I just fetched 8.1.6 to check but I won’t habe time to do it until next
week.

Hi Robert,
Are you able to file a bug with the offending image?
The engine does handle colour profiles in many cases so there may be an issue
with that kind of profile (if the image has one).
Of course, if the image does not have a profile then it might the engine isn't
using an appropriate de
Not only that, but a PDF can have embedded objects, each with their own ICC
profile. For instance, a logo should be using a saturation intent and absolute
colorimetric profile to make sure the color remains constant. Think Home Depot
Orange. A photograph however might need perceptual intent with

I suggest you try LC 8.x anyway, since LC 7.x is no longer maintained.
Moreover you'll find many many new features in LC 8.x :)

It sounds like I must venture into LC8-land or see whether I manage to
get by with sRGB yet…

Thanks for pointing me in the right direction. The images are indeed
CMYK. The stack is used to produce a PDF file and the printing shop
requested CMYK. I just checked that last year we had indeed used sRGB
not CMYK.

Hi Robert,
This is likely down to the colour space the images are embedded with.
Preview will respect the colour space whereas LC will not in some cases.
Make sure the jpg is saved with the sRGB (IEC61966-2.1) profile to maintain
the correct colour. And make sure it's not CMYK.
