Layers exported to a PNG
Using the script below, I'm doing an export to a PNG file:
EXPORT_RASTER FILENAME=c:\temp\bishop.png \
While examining the resulting PNG with the Windows Photo Viewer, I discovered that I could zoom
the image (I didn't know that this could be done). I assume that Global Mapper did this by
writing multiple layers to the PNG (I'm probably not using the right terminology, this is all
new to me).
How can I limit Global Mapper's export to the top most layer?
