John Hewson commented on PDFBOX-2681:
-------------------------------------
The license starts off well by granting the right to bundle the profiles with
application software:
{quote}
Adobe also grants you the rights to distribute the Software: (a) on a
standalone basis (b) as embedded within digital image files. (c) as embedded
within hardware products that author digital images, where there is no End User
access to the Software, and (d) as bundled with your own application software,
provided that you comply with all the distribution requirements in Section 3
below.
{quote}
The distribution requirements in Section 3 include the following terms, which
are fine:
{quote}
If you distribute the Software on a standalone or bundled basis, you will do so
by first obtaining the agreement of the end user under the terms of either the
Adobe End User License Agreement ("Adobe EULA"), attached as Exhibit B, or your
own license agreement which (a) complies with the terms and conditions of this
Agreement;
{quote}
It's not clear what "this Agreement" means, does it mean the current license
which we are reading, or does it mean Exhibit B?
In the first case, we might be ok to redistribute the files under that license.
In the second case, the license in Exhibit B only provides these rights:
{code}
Adobe also grants you the rights to distribute the Software only (a) as
embedded within digital image files and (b) on a standalone basis. No other
distribution of the Software is allowed; including, without limitation,
distribution of the Software when incorporated into or bundled with any
application software.
{code}
Which would permit PDFBox to redistribute the ICC profiles, but wouldn't allow
end users or developers to redistribute PDFBox.

> Key: PDFBOX-2681
> URL: https://issues.apache.org/jira/browse/PDFBOX-2681
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 2.0.0
> Environment: Tested on OS X 10.10, Java 1.6 / 1.8
> Reporter: Jon Wu
> Attachments: Shading2Function2CMYK.pdf, Shading2Function2CMYK.ps,

> In the attached gradient-test-photo.pdf, there's a photo with a gradient on
> top of it. The colors in the gradient are CMYK. When rasterizing this test
> file with PDFBox 2.0.0 SNAPSHOT 20150209, the resulting image's gradient is
> different from the original and the colors of the photo under the gradient
> look significantly different vs the display in Adobe tools like Illustrator
> or other compliant PDF readers.
> Issues:
> - Color hue is wrong. Is this a CMYK to RGB issue?
> - Opacity of gradient is wrong and much different. The jpg from Illustrator
> shows much more of the photo without a gradient over it.
> Without a photo, there's still a difference, but it's much harder to see.
> Example in gradient-test.pdf where the same gradient is drawn over a grey
> rectangle.
> If I convert the PDF to RGB in Illustrator first and rasterize the RGB PDF
> with PDFBox, the result is nearly identical between Illustrator and PDFBox so
> this seems like a CMYK conversion issue in both the general color conversion
> and maybe how the gradient is calculated.
