Hello dear Ignition’s fan.

I’m doing some test with the pdf viewer in Vision. I’m loading a pdf file of 3Mb and 134 pages.

The gateway is on my personnal computer as well as the pdf file. I’m using Ignition 8.

1- Loading pages takes time (a few second). It is almost instantaneous in acrobat.  
2- The rendering is not terrible. Resolution is not very good.

Any comments or idea?
