Problem with reference/thumbnail auto-generation for pdf files

[Jonathan Chu]

Hi everyone,

We are running AtoM 2.4 on Ubuntu for St. John's College of the University of Hong Kong.

We have been using AtoM for almost 1 year and the reference/thumbnail auto-generation function has been working fine for both photos and pdfs. However, when we tried to upload a pdf file yesterday, both the reference and thumbnail were not generated. The result is as shown in the following screenshots:

For the carousel:

For the relevant archival description page:

For the digital object edit page:

This is a new problem for us. It does not affecting image (jpeg) files. At first, it also did not affect pdf digital objects uploaded earlier. The master file is still there, and can be accessed by clicking the "file" icon. We have also tried the "Or auto-generate a new representation from master image" function on the edit page, but does not work.

We found a similar topic in this group: https://groups.google.com/forum/#!searchin/ica-atom-users/auto$20generate%7Csort:date/ica-atom-users/lQ0wt2SnWqY/lzxkYivU-ncJ. Our administrator followed the command for regenerating digital derivatives mentioned there (i.e. php symfony digitalobject:regen-derivatives). The data log after running this command is as follows:

identify: not authorized `/usr/share/nginx/atom/uploads/r/archives-of-st-johns-college-hku/e/b/1/ebla905bablc7b33bca9bbbb079e58a817df731e91687f732359e6ac5a/SJH-03_w.pdf' @ error/constitute.c/ReadImage/412.

Following this, all other pdf digital objects are plagued. Both references and thumbnails have disappeared.

Has this been encountered by anyone? Is there a solution?

Thanks!

Hi Jonathan, 

I think that you might be running into the following issue, caused by a change in ImageMagick. Please see this thread for more information and a solution:

Once you have this fix in place, you can try the derivatives regeneration task again to see if it resolves the issue. 

Cheers,
