Question Convert command from ImageMagick does not work, and saying convert: unable to open image :

[questhk09]

Hi,

I’m trying to use convert command from ImageMagick like below by placing in.JPG right under httpdocs, and had an message like below. I’ve also tried to place the files several other directories in order just to test to find out what will happen and the results were same.

[root@server-XXXXXXX-X ~]# convert in.JPG –strip out.JPG

convert: unable to open image `in.JPG': No such file or directory @ error/blob.c/OpenBlob/2589.

convert: missing an image filename `out.JPG ' @ error/convert.c/ConvertImageCommand/3015.

I do not think that the problems come from the directory issues, and have no idea what is casing this. I would appreciate if you could give me some tips.


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

I think it is ImageMagick issue, but not Plesk. Try to find solution in ImageMagick forum ImageMagick - Search

Hello,

Could you check the name of file ("in.jpg" and "in.JPG" two differ files), file permissions with command `ls -la`? Also, be sure you run `convert` in a directory with files because you do not use an absolute path to files. Could you run the command with absolute path?

Is enabled selinux on your server (check output of command `sestatus`)?

AYamshanov,

Thank for great information. I have 2 questions now.

1.Regarding directory issue, what convert command line should I write if there is in.jpg under the below directory?

/httpdocs/upload/temp_image/in.jpg (out.jpg)

[root@server-XXXXXXX-X ~]# convert.........

2.Regarding permission issue, what command line should I write to check if it's ok or not? If it's not, then how should I grant permission?

 

[AYamshanov]

Could you post there an output of next commands...
1) ls -la /
2) ls -la /httpdocs/upload/temp_image/
3) whereis convert
...?

AYamshanov,

Thank you for your time.

I tried and I wonder if it's what you want me to do.

[AYamshanov]

So, in root (/) directory you do not have a httpdocs directory. That's why you get an error "No such file or directory". A correct path should be like "/var/www/vhosts/example.com/httpdocs/".

AYamshanov,

I tried below and had no error message. Does it mean that convert -strip command line work?

[root@server-XXXXXXX-X ~]# convert /var/www/vhosts/XXXXX.com/httpdocs/upload/temp_image/in.jpg -strip /var/www/vhosts/XXXXX.com/httpdocs/upload/temp_image/out.jpg
[root@server-XXXXXXX-X ~]#

 

[AYamshanov]

Hi,

Did you get file out.jpg? This file looks like you want? If yes, then the command work

 

[questhk09]

AYamshanov,

Thank you for your time. I really appreciate it.

I'm still working on this since it seems that ImageMagick command line is not eliminating exif data from jpg file.

Anyway, unless you taught me how to write the collect path not to receive an error "No such file or directory", I would not have proceeded forward to find out whether or not exif data were eliminated.

I'll keep you updated about the progress.
