Image displayed without color (Red changed to Black)

Open the attachment. The logo and company name on top right is in black, but it should be in red.

File is correctly displayed with gs and a commercial java product whose name starts with j. File is incorrectly displayed with PDFBox and a commercial java product whose name starts with i. PDFBox complains about a bad icc profile and uses the RGB colorspace instead.

Chrome display this in blue (should be red). I also reported a bug to them:

Acrobat Reader and SumatraPDF (MuPDF) can display this correctly in my test.

I've briefly looked at this PDF file, using http://brendandahl.github.io/pdf.js.utils/browser/.
I'm not sure if it's relevant to the issue at hand, but I noticed that just prior to painting the image (with /R80 Do), the Graphics State is set (through /R79 gs).
That particular GState includes a transfer function entry (TR), comprised of an array with four functions. Hence I'm wondering if we would need to parse those transfer functions, and then apply them when painting the image (in canvas.js, similar to how transfer functions are handled for SMasks).

@Snuffleupagus we can always replace functions by LUT if we cannot perform color transforms on the the core side. See also #6723 and #5046 (comment) .

Mac OSX Preview displays the same way as us (see screenshots of PDF.js, Chrome, Preview, Adobe Reader):

@WalterYongtaoWang Are you the author of the PDF file, and if so may we include it in our test-suite?

Here's a document that has both: page 4 has an array of transfer functions, page 11 and 12 have a single transfer function for all colorants. This is a NASA document (I googled "Planetary Systems Branch") , thus not copyrighted.

Another non copyrighted PDF with a single transfer function:

@Snuffleupagus I'm really sorry, this is from our customer and they don't want to include this PDF file into the test suites.

@WalterYongtaoWang Is there any way you could generate a minimal test case, i.e., a PDF file with only the logo in it and no other data? If that's also not possible, we might need to look into creating a reduced test case from this PDF, which will be hard I'm afraid :(

I made some changes. Please included this one in your test suites. Thanks.

@WalterYongtaoWang Awesome, thank you for providing this file!

https://bugzilla.mozilla.org/show_bug.cgi?id=1149713 contains another example of a PDF file where some images utilise transfer functions.
