Description (last modified by cblackburn)
The imported "BIG" image
data_repo/test_images_good/nikon-jp2/DapiFitcTexRed001.jp2
has initial rendering settings (thumbnail etc) very saturated, probably due to incorrect min/max calculations (see screen-shot).
These same rendering settings are also picked when you "Reset" the rendering settings in Insight.

Is this image an "fs-lite" format? If not the problem may not be with the BfPixelBuffer? min/max calculation.

The min/max values look to be okay. The default rendering setting on two channels are wrong.
A similar file: data_repo/from_skyking/nikon-jp2/kira/DapiFitcTexRed008.jp2 has the correct rendering settings when imported.

It looks like for two channels the lower value is calculated okay but the upper value is out by a factor of 10 or so.

Just imported this plate onto the windows server - all are 'BIG' images and rendering settings are initially saturated.

Forgot to bring that point today.
We may want to turn off the "best guess" and use the min/max.
comment:8 Changed 8 years ago by wmoore
You mean just for Big images? But strange that this is working for most images, and that 'reset' returns it to the saturated settings.
