FILE_PREVIEW_MAX_SIZE not working

[Guilhem30]

I'm using seafile pro 6.2.9. Modifying the FILE_PREVIEW_MAX_SIZE setting does not work. Previewing a file over 30MB fail. The only log I could find is in the seahub.log file :

2018-02-20 15:58:39,377 [ERROR] seahub.thumbnail.views:77 latest_entry [Errno 2] No such file or directory: '/opt/seafile/seafile-pro-server-6.2.9/seahub/seahub/../../../seahub-data/thumbnail/1024/64e67c776d96d7b7629ef24bff97338a25e97ece'

In pro edition, for preview doc/ppt/excel/pdf, there is another option 'max-size'. The option 'max-size' is setted in seafevents.conf. You can refer to 'https://github.com/haiwen/seafile-docs/blob/master/config/seafevents-conf.md'. AND you need to restart seahub so that your changes take effect.

We are trying to preview high resolution images. We have tried to modify this max-size parameter too but it's made for other filetypes so we weren't surprised that it didn't work. Is it possible to preview higher than 30MB images with Seafile pro ? If so, we haven't been able to file any error log to tell us why it doesn't work. Thank you for your help.

I'm afraid it is not possible yet. The limitation of 30MB is written in the code currently.

@Guilhem30 hello, for previewing large size images, try add the following settings to conf/seahub_settings.py

# Seafile only generates thumbnails for images smaller than the following size.
THUMBNAIL_IMAGE_SIZE_LIMIT = 30 # MB

# Default size for picture preview. Enlarge this size can improve the preview quality.
# NOTE: since version 6.1.1
THUMBNAIL_SIZE_FOR_ORIGINAL = 1024

Note, we really don't suggest you set these settings too large, because it will cost many many many memory when generating thumbnail for large images.

this is the manual: https://manual.seafile.com/config/seahub_settings_py.html

Thanks for the answer imwhatiam but this setting doesn't seem to work
