Thanks for your reply.

I have asked in the EXIFtool forum. I looked into the documentation of exiv2 and did not find a copy command there.

If all else fails I will have to do this with own software, which I try to avoid, of course.

Hello, my scanner delivers its raw data as multipage TIFs. I would like to tweak the images without changing the metadata. If the metadata are changed, the software no longer works correctly. Is there a way in imagemagick to "replace" the content of the sub-images without affecting the metadata? I ...

Strange. It should work without login. That the whole issue!

But here is the file again: https://filebin.net/82fzdgw50brlgy93

Thank you for your fast reply. I am using ImageMagick-7.0.5-0-Q16-x64-static.exe on a Win10 64bit platform. I have tried "magick convert dng:image.dng[0] test_0.tif" and so on with 1, 2 and 3, but it always extracts the same image. And I know that there are 2 different images in this file from the ...

Hello,

how do I extract the individual images in a multi-page DNG-file? The documentation states, that an explicit format is required like "dng:image.dng". I have tried this but it did not work.

Many thanks and best wishes

solved! magick was missing!

Now it works nicely. Once again: If all else fails, read the instructions ...

The images are RGB and the IR-channel from the scanner. I read the documentation and had thought the following command should do it: convert C1-VS_Dia_1410_R.tif C2-VS_Dia_1410_G.tif C3-VS_Dia_1410_B.tif C4-VS_Dia_1410_IR.tif -channel RGBA -combine VS_Dia_1410_test.tif But it does not work. I get an ...

Hello,

is it possible to create 4-channel TIFs with imageMagick from 4 separate TIF files, i.e. "bits per sample 16 16 16 16"?

Hello, just for completeness: The problem is solved. It was the metadata. In the original image the tag subfiletype for IFD0, IFD1 and IFD2 were "Full resolution image", "Reduced-resolution image", and "Transparency mask". But in the three-page-TIF created with imagemagick, all three tags were set ...

Good morning,

thank you very much for your help. Now the endianness is correct. Unfortunately the third image is still not recognized. So there must be some other issue. I will now look into the metadata and see if there is still some difference.

Hi, I had tried both versions: magick SF_Dia_4850_0.tif SF_Dia_4850_1.tif SF_Dia_4850_2.tif -endian MSB SF_Dia_4850_sim.tif magick SF_Dia_4850_0.tif SF_Dia_4850_1.tif SF_Dia_4850_2.tif -endian LSB SF_Dia_4850_sim.tif to create a multipage TIF. And both give as a resulting format the little endian ...

Good evening from Europe, let me describe my goal without reference to any commands in imagemagick. The scanner output is a multipage TIF (RGB, preview, IR) with a given set of metadata, which contain the information for the second part of the scanner software (after scanning) which is image ...

Hello, thanks for your answer. I am using ImageMagick 7.0.5-0 Q16 x64 2017-02-20 on Windows 10 from the cmd-window. The goal is a multi-page tif. I can see the pages of the output file with exiftool and in IrfanView, but there must be some difference to the original leading to the problem. I also do ...

Hello, my scanner delivers scans as 3-page TIFs: RGB-scan, preview (lower resolution), IR-scan. Images are 48bit/pixel for RGB/preview and 16bit/pixel for IR. I want to make changes to the RGB- and IR-scans and then recombine the images so I can continue using the results like the original files in ...

Sorry, but I do not understand what you mean. I do not use PhotoShop, but the tag is written by software B and has the structure XMP-Name_B:ScanFrames=' ... ', where the dots stand for a long text, holding information about the setup of the software.
