my doctor's office sent me a file I was supposed to print out and take to another doctor (normal thing to happen in healthcare) and they sent a TIFF

like, that's no problem for me, I have literally been a professional TIFF manager for the US government, and I'm all kinds of computers. but does the average person have even the slightest idea what the fuck a TIFF is, let alone the ability to print one?

@foone oh, I actually kinda know something about this. for some reason TIFF is like *the* medical raster image format. x-rays, retinal imaging, the works, it's pretty much all TIFF.

@foone I do, which makes me think that I'm not an average person perhaps?(IMHO the bigger question is how to print a TIFF without it eating a year's worth of ink, because Windows by default will go "hell yeah, I'm printing this at million dots per inch -snort- let's gooooo.)

@foone possibly! it's also an earlier standard than PNG so it was probably the only vaguely-widely-supported patent-free compressed image format for anything written before '98.

@foone I have a feeling their office staff are not computer touchers. Tiff was what our big old multifunction scanners all used to default to. I had to change it everywhere I went because that's a completely impractical file format for an office.

@lanodan @foone @leo I honestly don't get why they don't support TIFF.It's not like ImageIO plugins for it (namely TwelveMonkeys) aren't readily available.

@lispi314 @leo @foone I don't either but well I feel like smartphones are specially designed to be painfully restrictive even compared to PDAs.At least unless you install a whole bunch of apps (and likely get malware in the process…).

@foone For the past 30 years I’ve had to be my grandparents’ and parents’ IT manager and help them out on similar tasks for medical offices, banking, cell phones, etc. I have no idea what they would’ve done without younger family members to help them. At some point society needs to stop being abusive to its elders.

@foone I'm now wondering if some of the TIFF usage was down to people using TWAIN-adjacent image acquisition stuff 'cos it was easily available. 'cos I've seen sequentially numbered TIFFs used for CTs, which (unless they were like... using reels of film or something) wouldn't make much sense for an actual flatbed lolbut now you have me intrigued... what's the rub?

@gsuberland it's JPEGs. the Windows Imaging program in windows 98 could produce TIFFs encoded with JPEG, but they're not readable by most other TIFF software (or at least weren't in 2010 when I had to deal with this)

@gsuberland it's because the windows imaging component in windows 98 was made before the TIFF standard finalized the JPEG support, so it's not compatible with standard TIFFs with JPEG contents

@gsuberland for a LONG while the only way we could deal with this was to call up our subcontractor who would go pull up that file on the spare windows 98 machine they had, print it out, then scan it back in on a newer computer

@lispi314 @leo @lanodan TIFF is a bit of a security nightmare, it's been used to hack a couple mobile devices before. so they might just have thrown it out for security reasons, as they figured TIFF is rare enough that supporting it isn't worth it

@foone @lispi314 @leo Yeah although we got sandboxing almost since the start of smartphones and I'd expect TIFF to be rather easy to sandbox (at least SELinux/seccomp/landlock-wise) since it's an image format.

@foone Lossless and fax-adjacent? I can see why they sent a TIFF. Isn’t it the default for medical imaging? It was back when I was fussing with that stuff.Macs aren’t bothered by TIFFs, I can see how the other kids might throw up their hands, though. Surely the OS would hide the extension and just treat it like any other graphic format.

@foone I actually liked it when I got referred one time, because they entrusted me with a CD to take. That gave me all the time to see what I could use to look at my own X-ray imaging before the next appointment.

@foone all OS X derivatives (including iOS and iPadOS) have always been able to display and print TIFF files natively since probably the first developer releases (for sure the Mac OS X Public Beta; it seems it was part of OPENSTEP*), so probably that covers a lot of area, together with libtiff having been in Linux since at least Slackware 8 (before delving into the way back machine).*I found a link to libtiff 1.7 for OPENSTEP at https://ftp.nice.ch/pub/next/unix/graphics/_imagetools.2.s/imagetools/src/_netpbm-1mar1994/netpbm/libtiff/ which I guess dates it to prior than 1994; probably TIFF support was there for Mac OS Rhapsody as well… which brought me to https://netpbm.sourceforge.net/history.htmlI feel properly nerdsniped 😉

@foone It's always a TIFF! X-ray? TIFF. Ultrasound? TIFF. MRI? TIFF. Sometimes the company that did the scan has an app, and that's the only way to view the TIFF. Then you have to screenshot it to get a JPEG.

@foone @lispi314 @leo @lanodan I don't see how TIFF can be more of a security nightmare than PDF for example, since PDF can include images all encodings used in TIFF.

@casandro @lanodan @leo @foone So, libtiff, the C library, has had a lot of RCEs.PDF in theory could have those as well if one's viewer actually uses the library for image decoding instead of refusing to render it. It also has the issue of Turing completeness and a JavaScript runtime with possible sandbox escapes on top of that.TIFF decoding is implemented properly in TwelveMonkeys. Handling PDF safely requires ignoring significant parts of the spec because permitting arbitrary computation means risking hardware vulnerabilities coming into play.
