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()],
)

Is it possible to put multiple images, as layers, into a tif file and have them be read by photoshop.

I tried the following,

with tifffile.TiffWriter('temp.tif') as tiff:
    for img in data:
        data_block = bytes('Adobe Photoshop Document Data Block', 'ascii') + b'\x00'
        bim = bytes('8BIM', 'ascii')
        layer = bytes('Layr', 'ascii')
        img_bytes = img.tobytes()
        img_len = len(img_bytes)
        img_len_bytes = bytes(str(img_len), 'ascii')
        all_bytes = data_block + bim + layer + img_len_bytes
        byte_length = len(all_bytes) - len(data_block)
        bytes_bytes = bytes(byte_length)
        allll = all_bytes + bytes_bytes
        metad = {"37724": str(allll)}
        
        tiff.save(img, metadata=metad)
tif.close()

which works with preview (on mac) but not photoshop. Photoshop only sees the first layer...

Hi @cgohlke. First of all, awesome work! I got your library from stackoverflow that it might be helpful for me. What I need is to create a multi-layered tiff. Just the same like you exported tiff from your photoshop.

Here is an example of files: google drive where you have photoshop file and tif created from it and also images which was created from.

This I want to accomplish, when you open generated tif, photoshop needs to see as layers.

I tried multiple approach:

• generate psd and then with imagemagic convert to tif but without a success.
• generate a tif with wand library
• generate psd and convert with online tools ... and I'm complete stuck.
