Tilman Hausherr commented on PDFBOX-2917:
-----------------------------------------
Sadly not very successful either:
- immo-kurier_arsenal_93x62.pdf the barcode now has the wrong color
- Page 3 of PDFBOX-2348.pdf is too dark
- the Braun file is unchanged. This could be because your patch doesn't change
standard CMYK images, which do also use an ICC colorspace.
