ARGB decoding #5

Hi. Thanks for your previous answer.

Running a few tests, it appeared that csj2k cannot decode argb files. Do you confirm that fact, or were my files (encoded with XnView) malformed?

Thanks, Sylvain.

@sylvain46 Thanks for the report. If you could provide a sample that I could look at, that would be great.

Thanks in advance! Anders

Sorry for the very late feedback, @sylvain46! What kind of error do you experience? Does decoding fail altogether, or is it just a question of the alpha component not being taken properly into account? A sample image would help a lot.

Hi. Sorry also about the giant delay... I'm missing time myself too... ;) In the meantime I can't remember the image in question... Sorry... :\

I'll try to give a go to the xamarin version of your tool soon... But I don't think I will deal with a transparent channel.

Thanks again for your work on this project! Sylvain.

I've just tested on Android, and it was quite easy to decode jp2... Performance is however an issue in my particular case, compared to native jpg decoding...

Sylvain.
