Google Docs inline pdf documents displayed as black and white

Question

I embed pdf files (hosted on S3) in modules using google docs iframe in my rails application. Here is the code:

$modalBody.append( "<iframe src='https://docs.google.com/viewer?url=<%= @url %>&embedded=true' width='100%' height='800'></iframe>" ); 

The problem is that sometimes (apparently random) pdf files are displayed in black and white, even if the original download was in color. The only hint I have is that pdf files that appear as black and white usually have a very small color in them (for example, the one below). Any idea what is going on?

Answer 1

I believe this is a compressed type of RGB image in PDF. I tried converting RGB to CMYK, which sorts the work (I only have an old utility for this). I also tried to edit the original to add another image: http://tonywilk.no-ip.org/testpdf/index.html the pdf file is located at: http://tonywilk.no-ip.org/testpdf/test_out. pdf

This shows the color for the added image with the original monochrome - therefore, the Google viewer cannot handle the original compression type.

In addition to re-encoding pdf files, I am afraid that this will not help you - sorry!
