Rasterized Plotting

Element transparancy is a view attribute. I believe the default setting of the view attribute initially comes from your seed design file.

Raster transparency is a different topic, unrelated to the element transparency introduced in V8 XM. Completely transparent raster pixels can be printed in non-rasterized mode (although inefficiently by most printer drivers), but not partially transparent raster pixels. Partially transparent raster can only be printed correctly in rasterized mode.

do I have to enable transparency somewhere or is it on by default?

and what if I use trasparent raster files in the design? does the driver fall back to non transparent vector output?

For many reasons such as this I use modified pdf.pltcfg files which print directly to postscript printers or create temp pdf and open pdf reader for realistic print preview or to print using windows drivers to non-postscript printers. See this Google search for my other threads on the subject.

Of the plotter languages that MicroStation supports, PDF is the only one that supports vector transparency. This includes the Windows GDI calls used for print preview.

These are language limitations, not gaps in the MicroStation implementation.

Andrew,

Thanks for the reply. I did try the PDF print driver and it worked well. I did notice that the tansparent elements did not show up in my plot preview window as transparent is this normal? - Will vector tansparancy support be added to other plot drivers?

Thanks

Dan

Have you tried printing in non-rasterized mode to the MicroStation PDF printer driver? That's the only printer driver that supports vector transparency. It might be a preferrable option for you. Otherwise, yes, rasterized printing can take a long time.
