Greetings.
One of my customers has alerted me that the rgb settings for text and images are corrupted when put into the PDF via converter.
For example, open a word doc, add some text and set the text colour to RGB 29, 87, 160. Now print to the PDF Converter.
Open the PDF in Acrobat Viewer and use Pitstop or similar to check the golour of any piece of text - values are RGB 28, 86, 160.
The difference is not much for office/pc work, but it is significant if the document is purposed for print.
This happens with converter 2.08 - I have not yet tried with 2.10.
Is this a known issue and if so is it still an issue with 2.10 ?
(I suspect some rounding errors in the converter code - could you check it out pls ?)
RGB colours corrupted in PDF.
Well, two years have passed and more customers report more problems.
This time the colours are still becoming corrupted and not following the colour profile selection in the PDF printer.
Would anyone from Amyuni care to comment ?

Hello,
We already received e-mails to our Technical Support Department concerning this issue and replied by e-mail.
This inaccuracy is due to the way RGB are converted to pdf. The RGB values
are divided over 255 which give us a number between 0 and 1 with 32 decimals
after the coma. This number is truncated in the pdf files to a fewer
decimals. So when converting this number back to RGB a small difference
occurs.
Our developers are checking the possibility to lower this inacuracy. If this revealed possible it will be implemented in our next release.
