  • Run the 279 CIAT author corrections on CGSpace

  • 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
  • This results in discolored thumbnails, sRGB and CMYK:

Thumbnail in sRGB colorspace

Thumbnial in CMYK colorspace

  • I filed an issue for the color space thing: DS-3517
