I have installed Sierra and after the installation I couldn't import a jpg anymore as an 1-bit PNG in my Vectorworks 2016.
It remains 32 bit and therefore I cannot change it's color as I used to do.
Same thing happens to VWX 2017 Test Version.
VectorWorks 2013 still works without a problem.
Furthermore the plans which have already 1-bit Pngs in them although they show correctly on the screen when I try to export the plan as
PDF the 1-bit PNGs show only B&W.
I'm using a iMac 27'' 16 GB RAM, mid 2013
Anyone else has the same problem?
