Jpeg 2000 images and viewers

Post by dbarrall » Fri Aug 10, 2018 12:12 pm

Hi,

I am scanning a document and creating a Jpeg 2000 document. When I process the document in anothe rapplication I see the red tint to the document. ON opening this up in different viewers I either get a pure image or I see the image diplayed on the right of the attached file.

I have tried several viwers and at the moment it stands at 50% showing the uncorrupted image while the other 50% shows the corrupted image.

What standard should I be looking at.

Kindest Regards
David

Ok. File to obig at 5mb to add as an attachment.

Let me know if you have this OK.

I think it may be down to compression but want to make sure.

Pierre,

Of course.

I think this may be down to compression or something as I am trying to feed this into LIMB processing and I see the same results when using XNView. When I use IrfanView then I see no corruption.

Pierre,

Many thanks if this is fixed can you let me know what has been changed as I will need to go back to either one of my software vendors so that they can also enable the same fix.

Pierre,

Could this be down to the ColourSpace as I saw that the output I have from my document scanner is sYCC and the output from another source is SRGB. I did change the ColorSpace in Photoshop and the image was displayed correctly in XnView.

Do some viewers assume that the ColorSpace is SRGB while yours correctly read the type?
