I've noticed that colors are not correct in maxscript tools in 2012.
Possibly a gamma issue.

Here is a sample script.
Please compare the colors carefully.
Note how the colors displayed with ImgTag are darker then the Image viewer.

p = (getdir #maxroot) + "Maps\\adskMtl\\Finishes.Tiling.Ceramic.Mosaic.Blu" + "e.jpg"

b = openbitmap p
display b

rollout poo "poo"
(
imgtag n "fish" bitmap:b
)
createDialog poo width:400 height:400

Can anybody confirm they are seeing color differences?

I can confirm the colors do not match only when gamma is enabled in 3dsmax.

i don't use 2012, and i don't really want to try it yet.
my question is:
is imgTag bitmap always lighter(darker) than displayed bitmap, or just does look different?

I was just using a regular checkbutton, and it was always or almost always making it darker. But I did have it randomly make my bitmaps appear fine a few times... not sure why..

I always had gamma issues with gamma and UI bitmaps, I either display them with dotNet, or something like that:

originalGamma = displayGamma --get current gamma settings
fileIngamma = 1.0 --set the gamma override
i.images=#(thisIcon,"bitmap.bmp",1,1,1,1,1)
fileIngamma = originalGamma --restore gamma

Aside from gamma issues, imagebuttons always looked darker for me, not only in 2012. Also there is something wrong with alpha masking.

Chris from Autodesk has figured out the issue (and send me a fix for c++ sdk) so I am assuming this fix will eventually make it into 3dsmax.

Thanks Chris!
