Hello, apologies for reopening this issue. It's still happening in 2025 :(

I have vips version 8.17.0

My image has 8 pages.

None of these works:

vips dzsave demo.btf[page=N] x
vips dzsave demo.btf[N] x
vips dzsave demo.btf x

vips tiffsave demo.btf[page=N] x.tif
vips tiffsave demo.btf[N] x.tif

All of them say tiff2vips: tiled separate planes not supported

The vipsheader -a shows:

f: 54784x45056 uchar, 3 bands, srgb, tiffload
width: 54784
height: 45056
bands: 3
format: uchar
coding: none
interpretation: srgb
xoffset: 0
yoffset: 0
xres: 5802.9
yres: 5802.9
filename: demo.btf
vips-loader: tiffload
n-pages: 8
image-description: ImageJ=
hyperstack=true
images=3
channels=3
slices=1
frames=1
resolution-unit: cm
bits-per-sample: 8
orientation: 1

Do you have any suggestion? is it that I have to use a different symbol/key for the page?
Using imagemagick I can extract the second page, the first one is too large and imagemagick exits with an error.

bfconvert takes ages to convert btf to tif, I am still waiting, but then I will try to run vips on the converted image and see if that changes something.
