Run the 279 CIAT author corrections on CGSpace
2017-03-02
Filed an issue on DSpace issue tracker for the filter-media bug that causes it to process JPGs even when limiting to the PDF thumbnail plugin: DS-3516
Discovered that the ImageMagic filter-media plugin creates JPG thumbnails with the CMYK colorspace when the source PDF is using CMYK
Interestingly, it seems DSpace 4.x’s thumbnails were sRGB, but forcing regeneration using DSpace 5.x’s ImageMagick plugin creates CMYK JPGs if the source PDF was CMYK (see 10568⁄51999):
$ identify ~/Desktop/alc_contrastes_desafios.jpg
/Users/aorth/Desktop/alc_contrastes_desafios.jpg JPEG 464x600 464x600+0+0 8-bit CMYK 168KB 0.000u 0:00.000
I need to file a Jira issue for sure
