identify returns different results for HTTPS than for local source

Post by yasokuuhl » 2019-08-22T08:17:41-07:00

Hi!

I'm trying to extract metadata from DNG files via HTTPS.
When I run identify on a file on my local harddisc everything works as expected. But things get weird when I use identify on the exact same file via HTTPS.
Via HTTPS the file is not recognized as a DNG but as a TIFF. (this also changes the outcome of convert a lot)
With "-debug all" I tracked the problem and found out that for HTTPS ufraw-batch is never called. And also the intermediate .ufraw file that is usually created is not created in the case of a HTTPS source.

Also I'm having the same problem with Adobe Illustrator files - they are recognized as PDFs when the file is accessed via HTTPS. But for simplicity let's only talk about DNG for now.

Has anyone got an idea how to fix this?
thanks
Daniel

Re: identify returns different results for HTTPS than for local source

Post by snibgo » 2019-08-22T09:00:36-07:00

With IM v6.9.9-50 and 7.0.7-28 I get the same result as you: if I wget the file and identify it locally, IM processes it correctly as a DNG, but when IM accesses over the net it processes it as a TIFF and reads a thumbnail from it.

I don't know why IM gets that wrong. A developer would need to take a look.

Prefixing the remote filename with "DNG:" doesn't help because IM throws an error, possibly because of the two colons:

Code: Select all

magick identify -verbose  DNG:https://bitmovin-poc-input.s3-eu-west-1.amazonaws.com/xx_images/RAW_CANON_1DM2.dng

identify: unable to open image 'https://bitmovin-poc-input.s3-eu-west-1.amazonaws.com/xx_images/RAW_CANON_1DM2.dng': Invalid argument @ error/blob.c/OpenBlob/33
75.

Re: identify returns different results for HTTPS than for local source

Mostly identify will show tiff if you do not preface the file with DNG:. See https://imagemagick.org/script/formats.php
DNG R Digital Negative Requires an explicit image format otherwise the image is interpreted as a TIFF image (e.g. dng:image.dng).
But I am not sure you can do that with http:// or https://. I have not tried. But I suspect the two colons may be an issue. But it is worth trying.

Re: identify returns different results for HTTPS than for local source

Post by yasokuuhl » 2019-08-22T10:03:27-07:00

DNG R Digital Negative Requires an explicit image format otherwise the image is interpreted as a TIFF image (e.g. dng:image.dng).
When the file is available locally it works without explicitly specifying the input format though... (see sample call for local dng source in my initial post)

Of course I still gave it a try aswell. For simplicity I used a jpg input file this time to see if I got the syntax right:

Code: Select all

identify -verbose jpg:https://bitmovin-poc-input.s3-eu-west-1.amazonaws.com/xx_images/ingest/jpegadobergb.jpg
identify: unable to open image 'https://bitmovin-poc-input.s3-eu-west-1.amazonaws.com/xx_images/ingest/jpegadobergb.jpg': No such file or directory @ error/blob.c/OpenBlob/3497.
So, same result as you had, snibgo. Then I thought maybe the placement of the "jpg:" in front of the URL is wrong and maybe it must be within the URL in front of the filename:

Code: Select all

identify -verbose https://bitmovin-poc-input.s3-eu-west-1.amazonaws.com/xx_images/ingest/jpg:jpegadobergb.jpg
identify: must specify image size `/var/folders/wm/m3m6tf1s5sx8bw52dhk7c4nxkkhfhv/T/magick-53833Z6yD6gIQ3r1E' @ error/mvg.c/ReadMVGImage/186.
This seems to work better - at least the file can be found now. Removing -verbose from the equation results in this:

Code: Select all

identify  https://bitmovin-poc-input.s3-eu-west-1.amazonaws.com/xx_images/ingest/jpg:jpegadobergb.jpg
https://bitmovin-poc-input.s3-eu-west-1.amazonaws.com/xx_images/ingest/jpg:jpegadobergb.jpg=>//bitmovin-poc-input.s3-eu-west-1.amazonaws.com/xx_images/ingest/jpg:jpegadobergb.jpg SVG 0x0 16-bit sRGB 243B 0.010u 0:00.010
So now with explicit image format declaration the jpg is interpreted as an SVG...
I also ran the tests again with DNG and the behaviour was exactly the same as with JPG. Same error messages all the way and same SVG mis-recognition.

Does anyone think this warrants a bug report?

Try simply downloading the https webp file and save to webp. Then do identify on that. You can even pipe it

Code: Select all

magick https://...../image.webp WEBP:- | magick identify WEBP:-

Yes.

I think putting the format within the URL eg "https://somewhere/jpg:myfile.jpg" is wrong, and I think IM should complain. I'm not surprised IM gets confused.

But "http://somewhere/myfile.dng" should be read as a dng, not a simple tiff, and that seems like a clear bug to me.

(Personally, I prefer to "wget" the file, then process the local copy.)

Re: identify returns different results for HTTPS than for local source

Thanks for both your help! The download + piping method sounds like a workaround.
I would still like to see it work with HTTP directly - so I'll also make a bug report.

Where would be the best place to file that bug report in order for it to actually get developer attention? Here in the forum or on the Imagemagick github tracker?
Also: would you phrase it as "DNG not recognized properly via HTTP" or more as "Explicit file format not working for HTTP input"

I suggest you post in the bugs forum https://www.imagemagick.org/discourse-s ... um.php?f=3

I would go with your first title, to report that bug.

If you also wish to report that "dng:https://somewhere..." doesn't work, I suggest you report that as a separate bug. Each report can contain links to this thread and each other.

Thanks for all the help again!

As you recommended, I created two bugs for this issue:
