[ome-users] PNG images being auto-scaled upon BioFormats import

[Paul van Schayck]

Dear Balaji,

Thank you for your response. I noticed the problem is not limited to PNG
images, but also present in JPEG or other RGB images. Am I correct in
assuming this is a general problem with RGB images?

Is a trac issue that I can keep an eye on? Is there a work around possible?

Thanks,

Paul
