TBH I had seen that when I replied, I was thinking DPScan might do a
better job than older programs.
As I discovered by accident the Drawfile colour problem was sorted when I
used Windows "DPScan" to extract the Bitmap image out of the Drawfile.
On the PC side all .aff files are auto picked up by a particilar app,
"AspexDraw" (An association I set ages ago).
For pure Vector Drawfiles Windows side this is a perfect solution, but as
I've just discovered, any bitmap file contained within the Drawfile in
AspexDraw does not look good colour wise, and when extracted retains the
colour degradation.
Just for interest, I've posted upline at
http://www.triffid.co.uk/dstuff/Extract.zip one of the mistbank images as
extracted from AspexDraw.
The colours seem to be shifted towards Blue.
Interestingly, Tif, PNG and other bitmap files natively imported into
AspexDraw all render correctly colour wise.
Anyway, in the end there is a solution.
Win side Ovpro.
A graphic of the type Tiff or PNG saves out of OvPro Win as Drawfile, this
being the container for the bitmap image, can effectively be extracted
from the Drawfile using Win DPScan.
Clunky, but it works, and that's the main thing.
------------------------------------------------------------
Now back to my .BMP files, just to clarify a point in my bonce.
As long as the OvPro document remains Win side, the .BMP file saved out of
an OvPro frame as .BMP is a .BMP (This I know from much usage and
re-editing).
On the RISC OS side the .BMP doesn't display for reasons discussed earlier.
(I think, but by now my brain hurts).
So am I correct in my assumption... The plan is to create a filter for Win
side to Auto convert the .BMP into a Spritefile?
I've just looked back through the postings and you said.
"I might have a look at providing the .bmp filter for Windows, since that
would make things totally automatic."
Mmnnn! Wouldn't it be better to have a filter RISC OS side that accepted
the .BMP as a BMP and displayed it?
If I create the document using a BMP file RISC OS side, then go Win side,
it is still a BMP image and can be saved out as such.

Nb: Just for amusement...
Interesting what can be seen in Image Info, RISC OS side for a BMP image.
Type: Mode 20 Sprite
Size: 12765 bytes (The real BMP image is 230,454 bytes).
Dimensions: 10000mm x 10000mm
Pixels: 10000 x 10000 pixels (The real BMP is 320 x 240 pix)
Resolution 180 x 180 (The real BMP is 90 x 90 dpi)
Colours: 10000000 (The real BMP is 24 Million)
Now my brain really does hurt. ;-)
