Issue with JPEG image

Classic Servoy
1

I’m testing on Mac OS X 10.4.3 with J2SE 5.0 Release 3 installed and Servoy R2 2.2.3 build-335.
I have a JPEG image that Servoy cannot visualize.
You can download the image from here.
If I try to visualize it, Servoy launches the following exception:

I see ```
sun.awt.image.ImageFormatException: Unsupported color conversion request

I believed that Servoy could read all type of JPEG images, isn't it true?

Hi Xfox

Got following message when clicked on link in your post - maybe problem is with image rather than Servoy.

The image http://homepage.mac.com/xfox/scritta.jpg cannot be displayed, because it contains errors.

I’m using Firefox 1.5 on Win XP

I tried to load the image with Mozilla 1.8b, Camino 0.8.4 and Firefox 1.5 on Mac OS X 10.4.3 and I got the same error message, but I found that it’s a Mozilla bug that cannot yet visualize the JPEG images in CMYK color mode.
Opera 8.51 and Omniweb 5.1.3 beta 1 simply don’t show the image.
iCab 3.0.1 (ß379), Safari 2.0.2, Shiira 1.1, Shiira mini 1.1.1 and SunriseBrowser 0.776 show the image without problems.

So it’s definitively not a problem with the JPEG image, I think it’s a lack in the JPEG support of the present Java version.
Could someone of the dev team confirm this?
Can I expect CMYK JPEG support in the short time or should I have to fallback to use only RGB JPEG images?

Note:
To correctly view this message you should switch the text encoding of your browser to UTF-8 (see this thread for more information).

Found the bug in the Java Bug Database:
Bug ID 4924909: Reading a certain JPEG image fails with IIOException
Actually, it’s a request for enhancement.
I just voted for it.
There is a suggested workaround, too, if the Servoy dev team wants to have a look at it.

Seems like CMYK jpegs are still an issue displaying properly.

Is there a fix/enhancement/upgrade anytime soon to the image plugin?

Yes, there is a case to support this but not sure when will be fixed. Best thing would be to create a case with your desired enhancement/fix. More demands for a feature tend to make it more urgent.
