AutoCad :: Raster Images Convert To Objects

In the old days (15years ago) we scanned a lot of files to DXB, and simply imported the image into the .DWG as small objects. (I believe they were treated as polyline segments). The lines from the original scan became a series of small polyline segments (not joined) but the scanned image plotted as good as the original, and even better, the objects could be erased and a "hybrid" drawing created without xrefs or "embedded" raster files. You could manipulate the scanned objects with normal autocad commands, and they existed on Layer 7.

Now, I am forced to Import a TIFF and "embed" the object (if I want it to be a permanent part of the drawing), and edit it with seperate programs like Raster Design.

QUESTION: How to convert a "embedded raster image" into a DXB image?

The scanner used to do the work for me and save the image as DXB. It was not a "vectorization program", but the raster lines became small (not joined) polyline segments in the process.

I don't want to "vectorize" with a seperate program, because then it just "traces" with a zero-width polyline.

The old scanner used to save to DXB, now I don't even see that as an option.

Any words of wisdom about creating a "scan" that can become "objects" (even small dots) INSIDE the DWG file, instead of a "Raster Image" that has to be xref'ed or "embedded", and will not even plot to a DXB or HPGL format?

I have mostly TIFF files that I would like to "convert" to DXB, and not have to re-scan them. I hate that the Raster file is treated as a seperate xref or "embedded" Raster Image.

I KNOW we used to scan directly to DXB and bring in the objects with the DXBIN command!
