[Dspace-tech] Problems with JPEG media filter and Branded

[Schuster, David]

Are there limits to the size of the JPEG that the filter will create thumbnails of?  Our Marketing department provided me some files, but they are pretty big – 10 MB and when I run media filter on it I get

 

./dspace filter-media -i 11274/446 -p "JPEG Thumbnail" -v

The following MediaFilters are enabled:

Full Filter Name: org.dspace.app.mediafilter.JPEGFilter

org.dspace.app.mediafilter.JPEGFilter

original size: 6016.0,4016.0

x scale factor: 0.013297873

new size: 80.0,53.404255

created thumbnail size: 80.0, 53.404255

If I resize the file to 69 KB it runs the filter without a problem.

 

My memory is set to 2048 max do I need to increase that and what are the proportions?

Try the following command to boost memory before rerunning the filter media process

 export JAVA_OPTS=-Xmx1024m

David,

I'm able to generate thumbnails for images that are hundreds of MB and my max memory is also set to 2048, so your images should be able to go without a problem.

What version of DSpace and Java are you using? Is it Oracle or OpenJDK?

Try disabling

thumbnail.blurring

and

thumbnail.hqscaling

in dspace.cfg one at a time to get a start on where the issue is.
