can output tif keep layers ？

[jindili]

some small tweak to the example on pypi page,
tif saved successful, but the layer were flattern.

Is is possible to keep the layers on ouput tif image ?

from tifffile import imread, imwrite
import psdtags

isd = psdtags.TiffImageResources.fromtiff('input_2layer.tif')
res = psdtags.TiffImageResources.fromtiff('input_2layer.tif')

image = imread('input_2layer.tif')
imwrite(
    'output_layered_tiff.tif',
    image,
    byteorder=isd.psdformat.byteorder,  # must match ImageSourceData
    photometric='rgb',  # must match ImageSourceData
    metadata=None,  # do not write any tifffile specific metadata
    extratags=[isd.tifftag(), res.tifftag()],
)

Can you share the file? For the example I am using the layers stay layered, which is the purpose of the package. It is validated by assert isd == TiffImageSourceData.fromtiff('_layered.tif') in the docstring.

sure, here is the file
input_2layer.zip

Try isd = psdtags.TiffImageSourceData.fromtiff('test_issue1.tif') instead of isd = psdtags.TiffImageResources.fromtiff('test_issue1.tif')

Great!, the layer is now keeped.

Is is possible to add new layer and import data from another image file ?
I start a new issue for that.
