[wishlist] Support displaying inline tiff images (to support mails fom Mac Mail)

[AJenbo]

Binary package hint: thunderbird

When a user of Apple Mac Mail pastes images in a email body, they are attached as tiff images (can't figure out why they didn't use png), Thunderbird doesn't know how to display these and just shows a big broken square instead.
The files are available as attachments for download only.

Here is the header from souch an email.

Content-Type: image/tiff; name="PastedGraphic-6.tiff"
Content-Description: PastedGraphic-6.tiff
Content-Disposition: inline; filename="PastedGraphic-6.tiff"; size=31891; creation-date="Fri, 22 Oct 2010 08:49:06 GMT"; modification-date="Fri, 22 Oct 2010 08:49:06 GMT"

On all major Linux distributions, and with openstep on Solaris, libtiff is
included. (Which is BSD licensed, if that's a concern).

I didn't see any bug in all of bugzilla that proposed adding TIFF support to
Mozilla. The US Patent Office uses TIFF files for all of their images of
patents, which I ended up having to view source and manually download.

Is there interest in adding TIFF, or is it not a "web format" and considered
bloat? (It's more of a web format then BMP and XBM).

This support might also be very useful to online faxing applications, since
faxes are generally stored as TIFF files.

[Tenthumbs (tenthumbs)]

The big problem with TIFF is that it's not a streaming format. You
have to have the entire file before you can begin to display it. No
incremental display. That's one reason why it's not used much.

There's also the compression issue. LZW was one of the original
compression schemes so there are patent issues. Lots of people are using
uncompressed TIFFs to avoid this so you wind up downloading megabyte
blobs before anything happens. The one big win is CCITT G4 (fax)
compression which is usually better on b/w images than anything else.
That's why the USPTO uses it.

Overall, I don't think it's a good idea.

Indeed, TIFF is a poor choice for web graphics. TIFF is very old and very common
format, however. A lot of old image archives use it because it is still useful.
Commercial and governmental customers will need TIFF support.

[Bunchoffun (bunchoffun)]

The website http://www.ureach.com uses TIFF files for it's unified messaging fax

download. TIFF is still a useful format and I'd love to see Mozilla support it.

As others have said, TIFF is an awful format for the web. We shouldn't
encourage anyone to actually use TIFFs by adding support for it <insert comment

[Jg-jguk (jg-jguk)]

Hi,

Just have to speak now.

Legacy compatability is what computing is all about, 60% of software is
recycling, its the same with gfx files. It is essential to have support, but by
all means do not promote the use of TIFF at all. I agree completly to that.

Other browsers support tiff, and unfortunatily mozilla is not in a monopoly
dominating possition to declair that tiff should not be used on the web.

Name one.

Image browsers, yes. Web browsers, no.

Next you will be saying take out gif support as you do not want to promote
another legacy file format with some issues.
IE supports TIFF does'nt it?
JG

[Jason1-pobox (jason1-pobox)]

Depends on exactly what you mean by "supports". As far as I know, no
out-of-the-box version of IE will ever, under any normal circumstances, display
a TIFF file referred to using <img src=foobar.tif>. I realize that IE is vast
and mysterious, so if I'm wrong, please correct me (and provide evidence).

[R-contact2009-awhlink-com (r-contact2009-awhlink-com)]

Adding TIFF support won't create any noticeable overhead unless a user actually
loads a TIFF file. It won't encourage web developers to use TIFF images inline
on web sites because in the free marketplace, the inefficient TIFF file format
will lose out to the competition. Displaying TIFF files in "img src=" is not
required. What is needed is displaying TIFF files when the URI directly
references a TIFF file.

The up side is we broaden market share. There are corporate and government
environments where this would be useful. See this message, for example.

http://remotesensing.org/lists/libtiff_archive/msg00460.html

Finally, space imagery is often contained in TIFF.

[Melmanmozilla-1 (melmanmozilla-1)]

Please take comment #12 and comment #14 as if they were said by me, although
comme nt #14 starts saying support should be added (for me it means displaying
on an "img src=" tag), and then says that just the URI to the tiff should be
showed. I am for the first option.

[Bunchoffun (bunchoffun)]

I see that Mozilla 1.3 was recently released but still doesn't fix the problem
with TIFF files. Any idea when this will be fixed? I'll be able to move my
company to Mozilla as soon as this is done since we visit the patent website and
Ureach.com website daily. We don't need to display the TIFF in the browser, only
the ability to download this file type and view it in a seperate application.

Thank you for finding that the bug report I had, 221333 is the duplicate of this
one. I think the image was renamed wrongly gif, but it was a tiff format
orginally. To answer a question, in the comments, IE 5.5 supports .tiff format,
but not IE 6.0.
I think if it is not a big effort, Mozilla/Firebird supporting .tiff might be a
good idea, that way we will have a more 'complete' browser. My 2 cents.

Re: comment #11, Jason Summers: Konqueror displays TIFF images without a problem.

BTW all images in the online database of the patent office are TIFF.

[Derakk (derakk)]

From a document imaging and archival point of view, Tiff is still the de-facto
standard for the imaging of paper documents. It is a very efficient format for
bitonal images, and none of the other formats currently available really fit
this niche. Currently, document imaging is starting to move away from client-
server software to a web-based model. All web-based document-imaging systems
use some kind of third party plug-in to view tiff images, and most of them are
quite expensive. If Netscape/Mozilla added native support for tiff images, they
would instantly be the platform of choice for web-based document imaging
systems similar to the US Patent office.This is a feature I would really like
to see.

Example: An 8.5 by 11 document scanned at 200dpi
filesize format color space compression type
43KB Tiff B and W CITT group 4 as implemented in libtiff
84KB PNG B and W
100KB GIF B and W
455KB BMP B and W
462KB TIFF B and W uncompressed
544KB JPEG 256 grays

[Hemanr (hemanr)]

Yes, I completely agree.
I am a real estate sales person in Austin, TX, and the MLS (multiple listing
service) and other tools realtors use - they ask us to use IE only. And I am
reporting to the authorities my complaints about IE lock in. One of the things
they use is tiff support, which I think will help Mozilla/Firebird to be used as
a browser. Please bring TIFF support for Mozilla!

[Rschlem (rschlem)]

I have to agree to the need for tiff support.
Jpg images distort the colors. tiff is a much better system for printing.
It is condescending to make arbitrary esthetic decisions.
For instance, I would like to publish photos for a family history. I am hoping that folks who are
interested in these data will download and print the images for their own collections.
 Jpg doesn't cut the mustard.

[Joegwinn (joegwinn)]

The various comments to the effect that TIFF is too ugly to support misses the
point. The various national Patent Offices have agreed upon the specific TIFF
format, and that's what they will yse, whatever we might think. A big reason
that uncompressed TIFF was chosen was that legally, a totally lossless format
was required.

Many people will not be able to ditch IE unless TIFF display, file save, and
print are supported.

Plugger (http://fredrik.hubbe.net/plugger.html) can solve this (and other plugin
things) for Linux, but with limitations. It is a workaround but missing TIFF
support remains a bug to be solved.

How is this parity-ie? IE doesn't do TIFF without a plugin either.

I just tried it, and IE 6 SP2 certainly doesn't display TIFFs natively. I guess
the comments about needing IE to view TIFF images were misleading.

[Akkana Peck (akkzilla)]

Apparently now the patent office is using <embed> tags (type=image/tiff) instead
of <img> tags. Firefox doesn't appear to recognize there's anything there at all
-- it just shows a blank. If I assign an external helper program to image/tiff,
it still shows a blank area, but then image/tiff disappears from the helper app
dialog and can no longer be viewed or reassigned.

Is there a way to get mozilla to show the presence of tiffs inside <embed>, so
an external handler can be called?

[PFudd (kernel-pkts)]

I just went to the patent office as well, and encountered the TIFF problem.

What's worse is that there is no way to add a helper via the Firefox menus!

Edit/Preferences/Downloads/View & Edit Actions
This screen lets you search for an existing action, remove an action, or change an action, but you cannot add an action, like what to do when you get a TIF file.

Combine that with no available plugin, and you've got yourself a browser that CANNOT view US Patents. C'mon guys, I know you don't like software patents, but this is a bit extreme.

Just a note, as reported all over (Slashdot, et al), the LZW patent mess seems to be over (we hope):

http://yro.slashdot.org/article.pl?sid=06/09/29/1657233

So if anyone was avoiding this for that reason, mayhaps it is time to revisit TIFF support in Firefox?

[Srogers (srogers)]

I agree TIF is awful for the web, but Mozilla is supposed to be an application development platform, not just a browser. There are numerous situations where it would be useful to support TIF display that have nothing to do with using TIF on web sites. In my particular case, I'm importing photos in base64 for display in an address book built in XUL. Apple's OS X Address Book application uses TIF as the format for photos it embeds in vcards - but since Mozilla the "browser" can't display TIF, Mozilla the "Rapid Application Development Platform" also can't display a TIF that's sitting in an installed extension.

Saying "TIF is not a web format" is a very short sighted rationale for deciding whether to support the format in Mozilla.

[F-linus-g (f-linus-g)]

Perhaps TIFF images are "inappropriate" for the web, but they exist and have to be dealt with. My application has to deal with all kinds of images, and FF lack of TIFF support is causing me much grief. Safari happily handles all the images I (so far) have thrown at it.

it is true that tiff is a poor web format, but Mac OS X screen shots are defaulting to "pasteGraphic.tiff" and everyone else on our team use Apples Mail.app. When they send screen shots I have to open them in Photoshop. I would be happy if they just appeared in Thunderbird

[Bugzilla-zirro (bugzilla-zirro)]

Just a note, as far as I can see, screenshots in Macs does not default to .tiff, but to .png.

[Bobbyholley+bmo (bobbyholley+bmo)]

Adding support for an image format in the official releases of the platform means putting it in the web browsers of 200 million people. The only reason we would do this would be if we thought that the benefit of having this support in the hands of web developers outweighed the increased security threat matrix to our users.

We clearly aren't looking to promote TIFF as a web format. As such, the reasons for having support are 2-fold:
1) Convenience for some users visiting websites like that of the US patent office
2) Usefulness of the platform for other (non-web) applications.

Both of these use cases can be handled by an extension. Interested users can install it, and xulrunner app developers can ship it with their product.

I don't think that Joe and I have much interest in writing such an extension ourselves anytime in the near future. However, we would gladly guide and support its development. If anybody is interested in writing one, please ping bholley or joe on irc (#gfx).

[Joe-drew (joe-drew)]

TIFF is great for print and film, but not for the web. It's too complex and not used on the web. Its uses do not justify the increased threat surface it implies.

[Bugzilla-zirro (bugzilla-zirro)]

Personally I have heard enough to conclude that TIFF support isn't needed, and might infact damage the web if supported. I suggest that if you don't have a very good reason which has not yet been brought up here, then there is nothing more to discuss.

[Bugzilla-zirro (bugzilla-zirro)]

TIFF is now supported in the IE9 preview (they don't give any specific reason for adding the support). I still think we should avoid supporting it for the sake of the web.

[Bugzilla-zirro (bugzilla-zirro)]

More interestingly, also supported in the IE9 preview is JPEG-XR. See bug 500500 for this format.

Well, then many Apple Mail users apparently don't find that setting, I'm usually getting those as (uncompressed) PastedGraphics.tiff inline images or attachments, thus it appears to be a not uncommon use case at least for e-mail.

Since ImageLib doesn't support it, neither Thunderbird nor SeaMonkey can display TIFF images in the message body or as attachment either. On the other hand, BMP is supported as inline format, which is not better at all than TIFF and doesn't even support compression. So, at least this is rather inconsistent.

Is there a pointer to such an extension for web or mail/news content?

On the Mac:
Screenshot is png, BUT
I paste to Preview, than <CMD>C and viola, it's a tiff
So tell the Mac users to direct paste into mail!

[Spurred-on (spurred-on)]

In response to TIFF displaying: For Windows OSs there is a file viewing application called Quick View Plus. It adds file viewing for over 300 Windows, Macintosh, Internet, and DOS formats and opens the files either as a stand-alone in the Quick View Plus program or from within file managers and browsers. It's handy for opening file formats for which there is no program installed on the system with which to otherwise view them.

(https://avantstar.com/metro/home/Products/QuickViewPlusStandardEdition/Info/Overview

One of the most visually intense TIFF sites is NASA and its related Hubble, JPL and other sites. Beautiful, but huge files. (132 MB 7546 X 7518 X 24 for example) When accessing a TIFF image in Firefox, Quick View Plus is invoked and it displays TIFF file in a Firefox tab. I do not know of a similar program for Linux, but if NASA and JPL use Linux and view their own TIFF images on the Web, I would think there is a Linux program that would work as a Firefox extension.

When trying to insert a file into a Thunderbird message, the TIFF file format is not available for selection. Opting for "All files" and selecting a TIFF file does not invoke Quick View Plus and no image is displayed. (Just the "broken image" box.)

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Outdoorchris (outdoorchris)]

To all those arguing the pros and cons of the TIFF file format, in my opinion I think you are missing the point.

- Mozilla Thunderbird does not support the TIFF format for inline images
- Thunderbird does not handle tiff images in a way that clearly explains to the non-technical user why they can't view the inline image in Thunderbird.
- the TIFF format is still commonly used, and will be for some time
- most email clients support the TIFF format
- most webmail clients support the TIFF format
- most professional image editing applications support the format

I understand that there arguments for or against handling various file formats in browsers. Website developers should only work with those that are universally supported. Emails clients, though, should support any sent attachment, inline or otherwise. At the very least, Thunderbird should display an appropriate error message indicating that it does not support inline TIFF images. Thunderbird could also provide access to the inline TIFF image as an attachment. The current handling of TIFF images by Thunderbird is clunky and confusing. Not resolving this issue will turn away many potential users of the Thunderbird Client.

[Akaihol+mozilla (akaihol+mozilla)]

Today I received an e-mail with an inline or embedded (I'm not sure what's the difference) image.

The image doesn't appear, only a "broken image icon" is shown in the upper left corner of the image area.

The image does not appear as an attachment.

If I right-click on the image, there is no "save image as" option, only "Select All" and "Copy Image". The "Copy Image" function doesn't work - if I try to paste into The GIMP, it tells me that the clipboard doesn't contain an image.

This is Thunderbird 9.0 on Linux Mint 12.

*** CONCLUSIONS: ***
1. I can't view the image even in an external application.
2. There's no reasonable way to get the image file out of Thunderbird.
3. I can't use Thunderbird when communicating with our graphic designer.

*** SUGGESTION: ***
At least make it possible to save TIFF images.

[Luke1410 (luke1410)]

I've to second Chris O's point here. If Thunderbird relies on ImageLib to support different image formats, tiff should be supported IMO.

Having a current mail-client not being capable of showing different image formats is a relevant draw-back in my opinion.

So if the "proper" way to add tiff-support to Thunderbird is to add tiff-support into ImageLib, here's my vote for this issue to be taken care of.

If the "proper" way is to handle image formats which are unsupported by ImageLib in Thunderbird differently, then I don't mind much in whether tiff-support is added to ImageLib or not.

[Luke1410 (luke1410)]

If this is considered not a valid feature request for ImageLib and hence is kept in the state "Won't fix", IMO issue 171514 shouldn't be considered a duplicate of this issue.

[Lrozenblyum (lrozenblyum)]

Are there any chances the WONTFIX status be changed to something more optimistic?
It's really a nice to have feature

[Mtanalin (mtanalin)]

By the way, native TIFF support would be useful for creating browser-based viewer (as an extension) for local images even if TIFF support was not quite reasonable for the pure-web purpose.

Lack of TIFF support makes such possible browser-based viewer of quite limited usefulness since many serious lossless graphics (e.g. scanned photos or other documents) are usually in TIFF format. Web browser is currently more than just a _web_ browser.

[lilydjwg (lilydjwg)]

I got here because an online PPT previewer from Tencent email service uses TIFF. Also, some people send TIFF screenshots as mail attachments so I can't view them directly in the web mail page. It seems that some screenshoters love TIFFs so much...

Actually that would be a good riddance and I personally won't miss it (nothing of value is being stored as GIF nowadays, and this format is laughably inefficient) and will be the first to jump on the version without gif support. I already block them in uBlock Origin anyway, so it would be less "dead" code, which is always good because it's less attack surface.
TIFF at least has some use cases, at least compared to GIF which doesn't have any valid use cases whatsoever.

[Luke1410 (luke1410)]

@sausagefactory0, do you have any empiric evidence supporting your statement that GIFs don't have any valid use cases?

If not, then IMHO this kind of attitude to conclude from one's personal opinion that the "rest of the world" (or to put it in this context here: "all other users of Thunderbird other than yourself") without any doubt will see it the same way, is very dangerous and can lead to really bad decisions resulting in loss of the user/customer base.

[Saint-snit (saint-snit)]

> Actually that would be a good riddance and I personally won't miss it

There may be good reasons for webmasters to avoid GIFs. Some webmasters will use them anyway. Perhaps they are ignorant of these reasons, or perhaps they disagree with them. It really doesn't matter.

A well-designed web browser will display a subpar web page -- including nonconforming HTML and, yes, nonoptimal image formats -- despite such a page's design flaws. A poorly designed web browser will decide what webmasters should and should not do, and attempt to police them by choosing to hide parts of their pages. This more likely to drive users to a better web browser than it is to make recalcitrant webmasters change their pages.

> nothing of value is being stored as GIF nowadays

It isn't your (or my, or any other individual's) place to decide what is "of value" across the entire world wide web. Users are diverse and find value in an enormous range of things.

(NOTE: substitute "TIFF" for "GIF" above for an equally valid reason this bug should be fixed)

GIF is typically more efficient (provides less file size) than PNG for low-resolution graphics — probably because PNG header is larger than GIF header. For example, a 1×1 white image is 43 bytes in GIF vs. 72 bytes in PNG.

But the whole GIF story is off-topic here anyway.

That's true, I only replied to that comment ("Next you will be saying …") to highlight that there _is_ some difference. Sorry if that sounds like heresy to some. Peace. :)

I am a photographer, and as such work with graphics files. JEPEGs are limited to a 24-bit color depth. TIFFs
have a 48-bit color depth. Anyone working in graphics would want to work with 48-bit images because they contain so much more information. However to make the files viewable in a Web browser, they must be dummied down to JEPEGs and lose much of their available information.

NASA publishes a lot of TIFFs

4K monitors are already common with Dell laptops and others, and 5K monitors are already becoming available. It'd be nice if Mozilla/Firefox came out with a browser ahead of the visual status quo rather than just keeping up with the past.

To be fair, PNG also supports higher bit depths, and also compresses a little bit better.

I'll put a $500 bug-bounty on this one. Can you get support committed to latest Firefox?

I like working with PNGs. They have some other advantages over JPEGs as well. PNGs may become my workaround to compensate for the inability to use TIFFs.

Thanks sausagefactory0.

[Jg-jguk (jg-jguk)]

sausagefactory0, why not start a petition, pledge $500 for the feature. I imagine if it hit $40,000 Firefox would implement it. That is only 80 people.

This entire thread seems to discuss the pros of other web graphic formats. Who cares -- this is a mail app, not a web browser?!? If Macs default to sending screenshots as TIFFs, then I need a mail app that can display TIFFs, because like it or not there are a lot of people who use Macs and who send emails to Windows users like me. This thread's been going for 17 years and my Thunderbird STILL doesn't display a TIFF. When I responded to the sender that I couldn't see their screenshot, my reply actually rendered the TIFF and they think I'm an idiot because I use a mail app that doesn't work "properly".

The upstream bug was marked WONTFIX 10 years ago. I'm updating the status of this bug accordingly.
