    Default jpeg2000 file is displayed as totally black

    I have a problem in viewing jpeg2000 files with IrfanView. IrfanView displays my 2-bit grayscale images (jpeg 2000) as totally black. If I use Oracle Outside In, I can see the image correctly.

    Does anybody know if this is a problem of IrfanView or the image?

    I've attached an example.

    The image displays fine in FastStone Image Viewer. The problem lies with IrfanView.

    Send it to Irfan Skiljan with a bug report. Help, About IrfanView for his address.

    Let us know what he says.

    Irfan send me a fixed version of jpeg2000.dll immediately. I was very surprised. The problem is fixed in version 4.52.0.0.
