PHP Imagick::readImageFile NEF filehandle detected as TIFF
Try to read an open filehandle results in imagemagick detect the fiel as a TIFF and then only reads the low-res preview. ` $filename='_X000001.NEF'; $preview='_X000001.jpg' $fh = fopen("/src-dir/$filename", "r"); $im->readImageFile($fh); $imageinfo = $im->identifyImage(); $im->resizeImage(1024, 768, Imagick::FILTER_LANCZOS, 1); $im->setImageFormat('jpg'); $im->writeImage("/dst-dir/$preview"); $im->clear(); $im->destroy();
// do other stuff with source file
fclose($fh); ` results in $imageinfo showing format = "TIFF (Tagged Image File Format)" and the output jpg is super blurry as it end being scaled up from the NEF preview a tiny 160x120px, instead of the full size NEF 3280x4928
I'm encountering the same issue with NEF pictures within the Memories app of Nextcloud.
They are using readImageBlob which picks the TIFF thumbnail instead of the source file (for ref: https://github.com/pulsejet/memories/issues/1054)
Hi, I won't be able to fix this in Imagick. Imagick is a thin wrapper around ImageMagick and so Imagick doesn't do any of the image processing itself.
I'd suggest reporting the issue at https://github.com/ImageMagick/ImageMagick
But also:
-
Try to replicate the issue using the command line ImageMagick tools. If you can do that, the maintainers of ImageMagick are far more likely to look at the issue quickly.
-
If you can't reproduce via the command line, making an example standalone C problem is another way of getting the ImageMagick maintainers to look at the problem. There's an example stub program you could base something on here: https://github.com/Imagick/imagemagicktest/blob/0be293bb3bf2b4bc6def249d585fb13f6572db1a/svgtest.c
If those fail, and the ImageMagick maintainers don't do anything, then post an example file here (I guess zipped up to get past githubs upload rules).
@Danack Thanks for the reply, I'll look into your recommendations when I have some free time. If you want to check some example files I've sent some zipped files in this issue on Memories: https://github.com/pulsejet/memories/issues/1054
I know that this is not a bug in Imagick but keeping this open as it might be good not to forget about possible upstream issue and possibly some support to report it there.
@Danack I've quickly hacked 2 tests:
- With your test repo creating a new standalone C file: https://github.com/mnogueron/imagemagicktest/blob/master/dngLowTIFF.c
- With the CLI
Both solutions works fine (I'm using ImageMagick-7.1.2-3) and produce good quality files, even with the NEF / DNG input.
However, using this code snippet in the PHP interactive shell, still yield bad quality files:
$file_path = 'my_picture.DNG';
$blob = file_get_contents($file_path);
$image = new Imagick();
$image->readImageBlob($blob);
$image->setImageFormat('jpeg');
$image->setImageCompressionQuality(85);
$image->writeImage('preview-output.jpg');
I'll keep investigating why there is a difference between ImageMagick and imagick.
@mnogueron assuming you're on some kind of Linux, I'd suggest running both versions through strace so that you can see exactly what your system is doing.
There could be differences in your delegates.xml file or which versions of libraries are actually being used.
You could also look at turning on ImageMagick logging. Which apparently might be configurable through MAGICK_DEBUG - though I'm not familiar with that at all.
@Danack I've been running both versions through strace and there is indeed something wrong in there.

In the script, the file is interpreted as a TIFF file and uses the TIFF coder, while using the CLI tool, it's correctly flagged as a DNG, and uses the DNG coders. The TIFF coder extracts the very low preview file from the DNG, while the DNG coder simply convert the DNG to a JPEG.
The DNG file type seems to be lost in the process. ~~Checking for getImageFormat() right before setting the new jpeg format, correctly returns DNG, so I don't really see where it get lost.~~ (It's actually flagged as a TIFF, bad reading on my side...)
I'll keep digging deeper!
And here are the logfiles with MAGICK_DEBUG="All" flag.

Directly reading a NEF or DNG file using readImage correctly resolves the right file type and Imagemagick picks up the DNG coder.However readImageBlob loses this information and picks up the magic byte for DNG files (II being TIFF files).
I tried passing a filename to readImageBlob to imitate the same behaviour, but the image is still interpreted as TIFF.
