How severely does this bug affect you?: 

●●●○ — It prevents me from completing a specific task with Vuo.

Steps causing the bug to occur: 

  1. Use Fetch Image to read a 16 bit Tiff / PNG etc
  2. Get info about the type of image in Vuo
  3. Vuo reads 16 bit files as 8 bit

Thanks for reporting, alexmitchellmus.

Confirmed that Vuo 1.2.3 reads 16bpc RGBA PNGs into 8bpc images.

Vuo 1.2.3 does correctly read 16bpc RGB PNGs. So as you said, removing the alpha channel would be a workaround.

And as you suggested, updating Vuo to use FreeImage 3170 may be a fix. FreeImage just added support for 16bpc RGBA PNGs in that version.

Would you mind attaching one or two of the images that aren't working correctly? Just want to make sure we test the fix on them.

;-) I mistakenly exported the 180-360° in PTGui with antialiasing- so don't try using the above image for uv-remapping! Right now it's just a nice and colourful image of two people talking about a vase! (In 16bit with alpha)

I did work out that PTGui can export without antialiasing: PTGui calls that mode nearest neighbour.

Hey @Bodysoulspirit. Yes it

Hey Bodysoulspirit. Yes it looks like its pushing out an image that is 8 bit. That's up to Team Vuo to work out if that is a bug or not, but having a 8/16 menu should/could be standard? If you want a nice gradient today, then simply use a Make Radial Gradient Layer, not Image- then render the layer at 16 bit.

Here is a comp, press spacebar to see the 8 v's 16 bit.
