Problem Saving TIFF Images

General Usage
1

Hi!

I’ve got trouble saving images in .tiff format.
Am I doing something seriously wrong with this code?
(I’ve got ImageMagick and QuartzImageIO installed)

using Images
using TestImages

img = testimage("moonsurface.tiff")
save("img.tiff", img)

This gives me the following error asking me if I want to install OMETIFF:

Error encountered while saving "img.tiff".
Fatal error:
Library "OMETIFF" is not installed but is recommended as a library to load format: ".tiff"
Should we install "OMETIFF" for you? (y/n):

If I install OMETIFF it fails too, because OMETIFF only reads tiff files as I understand it.

I think I have to convince FileIO to use ImageMagick or QuartzImageIO? Savers for these are already added. So if i use add_saver I get this and calling save still asks me to install OMETIFF:

add_saver(format"TIFF", :ImageMagick)
3-element Array{Symbol,1}:
 :QuartzImageIO
 :ImageMagick  
 :ImageMagick

Edit:

Solved it somehow by using the following:

io = ("myimg.tiff", "w")
save(Stream(format"TIFF", io), img)
close(io)

But now I’ve got an additional problem, because I want to save the image in 16bit. Is there a 16bit tiff saver available anywhere?

From my experience with Images, it will save the image in 16 bit if the eltype of your image array is 16 bit (i.e. N0f16).

When I convert the data array to N0f16 type, the image is stored in 16 bits.
