openslide jp2000 slides

Hi Talha,

Is JPEG2000 the "native" format of Omnyx, or is there something more "raw"? If
so, it would be interesting to have both formats (or at least have them in the
OpenSlide repository for future reference).

In the short term: you should check your scanner and see if there is a setting
that lets it produce "regular" JPEG/TIFF-files instead (I know our
Leica/Aperio scanner has this).

As Benjamin indicates (if I understood correctly): making some small tweaks
for TIFF-files would be easier to do than having to come up with full JPEG2000
support. We did this ourselves some time ago for Philips TIFF-files.

Just my two cents,

Hi Gilbert,

Thanks for your prompt response.

I just checked those TIFF files were produced with Omnyx , and i know Omnyx
scanners is not supported by openSlide, so is there any way-out for me so i
can read those images?

I am worried that only option left for me is to write my own driver using
 this  (
