Curious insight bug

[ppouchin]

Good morning.

Yesterday, a user told me she had encountered some problems while viewing images in Insight. I've managed to reproduce it, but I'm not sure of what triggers it...

This happens when viewing images with several channels in "split" view with compression set on medium or high. If the first three channels are red, green and blue (the order does not seem to matter), the red and green channels become binary images.

I noticed it happens also on images with only 2 channels : if they use two of the primary colors, the same behavior is observed as if a third channel used the missing primary color. For example, if channel 1 is green and channel 2 is blue, channel 1 will appear as a binary image (only in the split view with compression on) and if channel 2 is red, both will be affected...

To speed the display and reduce the number of calls to the server, we apply a mask to the image when the channels are red, green or blue otherwise we retrieve an image for each channel.
Then scale the returned image.
I will have to review that strategy depending on the compression level.

Thanks for the feedback.

I forgot to update the post.
The problem has been fixed.
