Two new system variables were added in AutoCAD 2007 to allow
you greater control over plotting drawings that contain large
raster image attachments or when plotting high resolution, large,
rendered/shaded viewports on large size media.
RASTERTHRESHOLD
Type: Integer
Saved In: Registry
Initial Value: 20
Specifies a raster threshold in megabytes. If the plotted
raster image exceeds this threshold, the availability of system
memory is checked. The plot is aborted if the image is too big for
the available memory.
RASTERPERCENT
Type: Integer
Saved In: Registry
Initial Value: 20
Sets the maximum percentage of available virtual memory that is
allowed for plotting a raster image.
Publish Drawings
DWF Files
Raster images in DWF underlays are not plotted when plotting to
DWF.
Plotting DWF underlay files that contain raster images can
produce unexpected results.
