I tried all the export formats with the same result.
In terms of code, its the standard VBA bulk file exporter that comes with CorelDraw 11...
I checked out the pdf guide to VBA that comes with Corel (dvba_pg.pdf) and it seems to say that the individual layers cannot be exported using Corelscript...
"Files are exported from the Document not Layer objects, since the range of shapes exported often extends over
multiple layers, and even over multiple pages."
This implies I cant use Corelscript, which is a problem as I've about 5000 images to convert!
If I export an image using the File-Export option within Corel it only picks active layers. I take it this is using a different command. Does anyone know if its possible to run these regular commands at the command line?
