Legacy ImageMagick Discussions Archive

I have several questions regarding its system operation.

[root@server-XXXXXXX-X ~]# convert /var/www/vhosts/xxxxxx.com/httpdocs/upload/temp_image/*.jpg -strip /var/www/vhosts/xxxxxx.com/httpdocs/upload/temp_image/*.jpg
Killed

1. Above is what I tried, and does it make sense to you from technical point of view? It says killed, and does it mean that ImageMagick took exif data off from all those jpg files in temp_image folder?

2. Is this command line something that I have to run every time I upload file to the application? Or will it take care of the task forever once I run the convert –strip command line?

You cannot use a wild card for both input and output using convert. If you want to process a whole folder of files and keep the output names the same as the input names, then use mogrify rather than convert. See http://www.imagemagick.org/Usage/basics/#mogrify

ImageMagick does not watch folders to run new image when the appear. You will need to use a cron job to do a timed command for any images in the upload folder and then move them after processing.

fmw42,

Thank you for your time.

Below is what I had after about 5 min when I run it, there are about 2000 jpg images in save_image folder, and since there are no error appeared after all, does it mean that ImageMagick mogrify command line eliminated all those exif data from jpg files that exist in save_image folder or I still have to check something ?

[root@server-xxxxxxx-x ~]# mogrify -strip /var/www/vhosts/xxxxxxx.com/httpdocs/upload/save_image/*.jpg
[root@server- xxxxxxx-x ~]#

When I check the website to find out it seems that pictures still possess exif data.

Regarding a cron job, I will work on it later.

What is your IM version and platform? Can you post a link to one of your JPG files that have EXIF data that you want to remove. I can test to see if it works on current versions of ImageMagick.

How did you check the images after running the command to see if the EXIF data was still there?

I just tested mogrify on one JPG image that had EXIF data and it remove the EXIF data according to identify -verbose P1050001.JPG

Code: Select all

mogrify -strip P1050001.JPG

works fine for me on IM 6.9.9.23 Q16 Mac OSX.

It also works fine using IM 7.0.7.11 Q16 Mac OSX.

Code: Select all

magick mogrify -strip P1050001.JPG

One other point. ImageMagick will read your JPG, decompress it, strip the meta data, then compress it again before saving when using convert or mogrify. That may cause a change in the quality of the result, since JPG is a lossy compression. If you do not want this to happen, then use EXIFTOOL to remove your EXIF data rather than ImageMagick.

fmw42,

Thank you for your time.

Below is the versions of softwares installed.

OS：centos-6 (x86_64)
Plesk 17.0.17
ImageMagick-6.7.2.7-6.el6.x86_64
ImageMagick-devel
php-devel
PECL imagick

When I saw the website, the particular picture(taken from iOS device) was displayed horizontally, because of the orientation data of the exif that the jpg file possesses, which should be shown vertically, which is also the reason why I still think that the particular picture still has exif data.

I tried below from your advice and found the orientation of the exif is "undefined" which should be ok to be shown vertically.

Do you know anything about what the orientation data of the exif should be in "this particular case" after mogrify command line eliminated the exif?

So it is typical of ImageMagick to show undefined for orientation after you strip the meta data. Once the EXIF orientation is removed, ImageMagick can no longer know what it was, which it had originally copied to its Orientation field.

By the way your version of ImageMagick is 6.7.2-7 2017-03-22. That means it is very old, but has been patched. The patch date is from March of this year. Perhaps you should check if there are any newer patches.

fmw42,

Thanks for your time.

The data I showed you was the one after I run mogrify -strip command. (Do you think that the jpg file is not containing exif data anymore? If it does not contain exif data anymore, then I wonder why the picture is still displayed horizontally.)

Before I decide to reinstall ImageMagick for a newer version or install EXIFTOOL to test again, I have to find how exif data differ before and after running mogrify –strip for new jpg file.

** So, how can I get "meta data pertaining to EXIF", the first data that you showed me to know exif data in detail?

Show us the data before you used strip. Perhaps the orientation was already correct. Or post and example JPG for which you are having trouble so we can test that.

** So, how can I get "meta data pertaining to EXIF", the first data that you showed me to know exif data in detail?

I do not understand this question. You can use

Code: Select all

identify -verbose yourimage.jpg

or

Code: Select all

identify -format "%[EXIF:*]" yourimage.jpg

or use EXIFTOOL.

to get the EXIF information. See http://www.imagemagick.org/script/escape.php

fmw42,

Thank you for your time.

>Show us the data before you used strip. Perhaps the orientation was already correct.

Then, why do you think that the picture was displayed horizontally which should be vertically when the orientation was already correct.

http://metown.info/products/detail.php? ... yname=test

* I've not used strip command yet for the picture above.

Sorry for being a foreign site.(URL contains double byte characters、and I'm not sure your os allows it.) This picture was taken vertically from iOS device and is displayed vertically in the iOS device, but once I upload to the demo site that I am developing now it will be displayed horizontally which is the reason why I think the orientation was added by iOS device.(This phenomenon never happen to the picture taken from android device, and exif orientation issue is famous for iOS device. )

What should I do in the end if the original data does not even contain orientation like your guess, yet it is displayed horizontally which was initially taken vertically?

Since I do not read the language on that site, I am not sure how to download it. I clicked on the picture and chose download file. But I may have only downloaded the preview file. Also note that some hosting service reformat the image. So it might be better if you do the following on your original file and show the results. When I do it the file has no orientation and no EXIF data.

fmw42,

Thanks. Sorry again.

Again, this only happen to the picture taken from iOS, not Android(hosting service has nothing to do with these different os). Since orientation is not the one that is causing the problem, what is causing this?

Perhaps I don't understand the issue. You said you were not getting the correct orientation. If the orientation is undefined, then that could happen, if there was a different orientation, but it was stripped from the image meta data. Again, I would need to be able to download the original image to see what is happening.

Fmw42 Thanks for your time. I really appreciate it.

The link below is the site that shows the original image, the one without strip and without uploading to the application. (I just sent the image to the web server from iPhone via FTTTP)

http://metown.info/upload/save_image/595.JPG

You can download the original image by clicking the 4th link from the bottom after you left-click the mouse. (Isn't it what you want? If it's not, should I send you the image?)

When I run commad I had results like below. Can you tell why the image is displayed horizontally which was initially taken vertically by seeing exif data?
