I'm trying to decode a jpeg that is in CMYK color format. BitmapFactory returns null. I googled around but with no luck. Is it possibile Android team did not the right job supporting all kind of color format?

I'm using Android 2.2.

Thank you so much.

Found the solution: loading the JPEG using the external library libjpeg compiled with NDK. It has been a hard work, but I did it!

Would you post some code showing how you did it? Then other users will benefit. – Placid 3/10, 2011 at 16:36

Since it's a mixture of Java and C it would be better if I could show the entire project. Where could I upload it in a safe manner? I mean, in order to make it available for a long time. – Chak 4/10, 2011 at 9:48

It's very possible I'd say:

Status of that issue is set to as new. It means it was not corrected, doesn't it? – Chak 30/9, 2011 at 9:55

Yes, so you're not likely so see any change soon. Isn't fixed on 2.3.6 at least. – Aboveboard 30/9, 2011 at 10:7

do you know other solutions? other libs for reading jpeg compatible with Android? – Chak 30/9, 2011 at 10:14

Porting/building lcms in Android shouldn't be impossible (but not trivial). littlecms.com – Aboveboard 30/9, 2011 at 10:44

I used libjpeg compiled with NDK :) – Chak 3/10, 2011 at 12:8
