jpeg2000 support

[rkrijger]

Which software do I need to display a JPEG2000 image in a CVI user interface panel?

I make BMP's of JPG-pictures first and then it works. Is that OK for you ?

[rkrijger]

Thanks, but no: it won't work. I have the JP2 files as input... It would help if there is some command-line tool available to convert JP2 to BMP/GIF/JPG, but... hey: NI should have something, right?!?

Regards,

Hi!
 
   If you have to dinamically load images, you may try some ActiveX control, just like Microsoft ImageList Control.  but, unfortunately, I can't tell you more, because I'm not able, on my machine, to use this component; when I told in another post to use it, the guy told me it worked.

Let me know if it works, if you want!

Hm, I have no experience with ActiveX (yet). Let's see what the official NI response is. But thanks anyway!

On Guillaume Dargaud site you can find an instrument driver for managing JPEG files.

I have used his instrument for PNG files and it does a great job but I have never used the correspondent instrument for JPEG, but it may worth a look.

I would just like to clarify the following distinction:

CVI 7.1 and later does have native support for the JPEG 1992 standard, which currently is the more widespread of the JPEG standards. CVI does not currently support the JPEG 2000 standard. If we see that the adoption of JPEG 2000 becomes more widespread, we will certainly consider adding support for it in a future version.
