Poor display of fine lines - any settings to improve?

[jdunfee12]

I have had issues with poor display of PDFs from CAD drawings that have fine lines. The fine lines tend to disappear unless you zoom in a significant amount. The one I have problems with at the moment, are actually poor quality PDF (I don't know the original source) that have a great deal of pixelation. So, they aren't good to begin with.

When I view the PDF drawing in Adobe, it is much easier to read and see the details, without having to zoom in as much. I have attached one of the drawings as an example.

Are there any settings in PDF-Xchange's viewer, that will improve the display of this sort of drawing?

Thanks,

Hello Joe,

Welcome to our forums.

Please download and try the Viewer's successor - the PDF XChange Editor:

And there should be a significant improvement.

In PDF-XChange Viewer, via Edit > Preferences > Rendering, the parameter "Smooth images" should be checked/activated.
In Adobe Reader, via Edit > Preferences > Page Display, this same parameter "Smooth images" should be checked.

PDF-XChange Editor, does not (actually) have such a parameter.
Eventhough the "smoothing" of images seems to be ON in the Editor.

Thanks for the input Willy - always appreciated.

You are right - Image smoothing is on by default in the Editor and there is a similar 'On/Off' option coming in the Editor at some later date with many more options later - but for now it was more pragmatic to set on by default than not.

thanks

I was on an older version. The current version has a much better display of these sorts of image.

Thanks,

We do not learn much with these kind of answers.

What was the release and build number of that older version ?
Was it PDF-XChange Viewer or was it PDF-XChange Editor, and what is it now ?
If it now is the Viewer, then still the question: is the "Smooth images" parameter ON or OFF ?

[jdunfee12]

The program was the Free PDF Viewer. I am sorry, but I no longer have the older version installed, so I can't say which is was.

However, regardless, in the new version, I did need to turn on the smoothing function for the best display, since it was off. Note that when I installed the new version, all my tool-bars remembered their settings, so it is possible that the smoothing setting was also remembered from the older version.
