Cannot open this TIF file

This TIF file

https://www.dropbox.com/s/pryu0d74gvt6x ... tiff?raw=1

will not open in any image editor/viewer I've tried, including PSP 2018 (32-bit), PSP 2018 (64-bit), PSP 8, and half a dozen others, except for IrfanView.

From googling I gather that it has something to do with Microsoft Office Document Imaging (MODI) which was discontinued after Office 2007. (I have Office 365, alias 2016.) I'd never heard of MODI until now.

Anyone have any no-brainer method of viewing this file in PSP please, as I'm curious about its contents.

I'm guessing IrfanView is displaying just one page of what is presumably a more complex multi-page file. That page (an aerial map) looks like this:

Your TIF file seems to use 16-bit to save the color, gray scale in this case. PSP and most other graphic tools might await only 8-bit for gray scale TIFs. Most of them probably use the same library, which is based on a reference from 1992. PhotoLine fails too.

EDIT: The reference says: "BitsPerSample: The number of bits per component. Allowable values for Baseline TIFF grayscale images are 4 and 8, allowing either 16 or 256 distinct shades of gray."

I'm not sure that it's a multi-page tif file. Irfanview can open multi-page tif files, showing the first page when opened but allowing you to use the Next File arrows to go through the pages. With this image there is no next page (or previous page) when this file is opened. Of course it could still be multi-page but Irfanview might not be able too properly interpret the tags that were created for the multi-page tif when it was created.

EDIT: It is not the Next File arrows that move through multi-page tiffs despite what I said above. It is the Up/Down arrows on the multi-page icon to the right of the Next File arrow!

If you want to open just this page in PSP then use Irfanview to change its color depth to a 256 paletted image and then you can increase the color depth again when you open it in PSP.

Also, according to a Microsoft forum there is a way to use MODI with Office 365. You might want to check out this link:

Thanks Joe, but the 'Next File' button in IrfanView is greyed out for the subject TIF. and my curiosity isn't enough to justify installing Microsoft Office Document Imaging (MODI).

Thanks Joe, but the 'Next File' button in IrfanView is greyed out for the subject TIF.

Hence my speculation that this isn't a multi-page tif. Or, as I said, one with which Irfanview can't interpret the page tags.

EDIT: Contrary to what I said in a previous post, It is not the Next File arrows in Irfanview that move through multi-page tiffs. It is the Up/Down arrows on the multi-page icon to the right of the Next File arrow! That said, those arrows aren't active either with this image.

FWIW, I continue to use MS Office 2007. So I just opened MODI from that and attempted to open the TIF image which I had downloaded. I got a msg saying "The selected file is not a Microsoft Office Document Imaging file." And it wouldn't open there either... So it would seem there may be some other problem associated with it

And I made the reverse mistake! I meant the up/down page buttons, which were the ones I tested.

Thanks for closing off that option, Ken.

I can open it in PSP 2018 but the image is black. If I do a histogram stretch or equalize, I get some black and white patterns, but certainly not what's intended.

Open it in Irfanview . Do Edit > Copy
Open PSP 2018 - Do right click the workspace and Paste as New Image.

Thanks. Interesting - and puzzling that it's necessary.

Presumably unrelated but after copying to clipboard from IrfanView, it took several attempts to get PSP 2018 to start loading and then a longish time to finish loading. With the paste finished and PSP 2018 closed, I then opened it again and it crashed with the rather familiar message, roughly "PSP 2018 (32-bit) had a problem and is closing".
