IssueTracker

This bug has been reported on the skia bug tracker. The referred image is there:
https://code.google.com/p/skia/issues/detail?id=69

What steps will reproduce the problem?
- Try to display the attached picture with android sdk or with the basis android browser. The particularity of this picture is that it use an embedded ICC profile and it is in CMYK.

What is the expected output? What do you see instead?
- instead having a pointer (the display) on my bitmap I have a null pointer and the following message in the logcat :
D/skia    ( 1537): --- decoder->decode returned false


What version of the product are you using? On what operating system?

I was able to reproduce the issue in Android: 2.2, 2.3, 3.0, 3.1, 3.2, 4.0

but probably it goes back to Android 1.0


Please provide any additional information below.
Here the code I used to call the skia decoder :

Bitmap bt = BitmapFactory.decodeFile(getFilesDir()+"/"+filename);
if(bt==null)
        Log.v(TAG, "\tError !!!!");

I used imagemagick:

convert -colorspace RGB mycmyk.jpg mybmp.jpg

mycmyk.jpg can't be decoded:
D/skia    ( 1537): --- decoder->decode returned false

and mybmp.jpg is decoded correctly.


No known workaround, the bug is probably in the low level (C) function that actually decodes the image, the only possible way I can think about to decode jpeg with CMYK colorspace in Android is to avoid the android BitmapDecoder and write a custom jpeg-decode function --- that wouldn't be as performant as the BitmapDecoder and probably some issue with memory management will raise as well, I may be wrong but Android (or at least some version of it) manage image memory in a different, low-level, space that's not directly accessible to the public API.


According to skia developers the skia code used in Android is a modified version of the one used by upstream, see comment https://code.google.com/p/skia/issues/detail?id=69#c6
