When I am trying to view a document using PDFJS the content in white color is rendered in black color and the content in black color is rendered as white color.

When reporting an issue, please make sure that you read https://github.com/mozilla/pdf.js/blob/master/CONTRIBUTING.md, paying special attention to the first paragraph. At the very least, you must provide a link to a PDF file that can be used to reproduce this issue!

@vijith2712 For future reference, when reporting issues:
If possible, please upload the PDF file to a file sharing service (e.g. Dropbox, Google Drive, Microsoft OneDrive or similar), and paste a link to the file in the issue, instead of sending it by email to individual contributors/developers.

Sending a PDF file by email should only be considered as a last resort for PDF files containing sensitive data, where making the PDF file publicly available through a file sharing service would pose a problem.

Jonas,
Any updates on why this issue is happening.

[timvandermeij]

The PDF contains a DeviceGray image with DecodeParams. Perhaps we do not handle those decode parameters correctly? It seems like a color inversion issue.

[vijith2712]

Can we expect a fix for this issue in the next release? Can you please provide ETA for this issue?

I think it's related to the predictor 2. This is related to issue #6289 but different bit size.

Interestingly enough, if you skip the bits === 1 code-path in readBlockTiff, see src/core/stream.js#L740-L749, and instead fallback to the default one, see src/core/stream.js#L758-L783, the PDF file appears to render correctly. Hence it certainly seems plausible that the code for the bits === 1 case could be wrong in some edge-cases.

@Snuffleupagus, i also reproduced the condition mentioned above, but i am unable to understand what is going on in the code, can you please guide me how can i understand what code does.

Closing as fixed by PR #7869.
