Hi Lars Thanks for sending the program, exactly what I was looking for. I notice that you set it up to save the image as a jpeg with a tfw, I will have to tweak the program to saveas a jgw file as AutoCAD's raster software does not recognize tfw when inserting a jpeg image. I assume whatever program you import the image into allows you to use tfw for jpegs?
Thanks to all that replied. Brian Cowper -----Original Message----- From: Lars V.

However, TFW has no coordinat system info. TFW is a very simple format, especially if the image is aligned to the grid, i.e. n o rotation. Then it basically holds just the upper-left X,Y and the map units per pixel in X and Y. I've put together a small app, and attaches the source code FYI. If the attachments don't get thru, I can send it as ZIP. The app uses the assumption that Pro exports with 96 dpi, which may not be true with VGA resolution (640x480), but who uses that anymore anyway :-) Best regards / Med venlig hilsen Lars V.

The way I go about it at the moment is to have my points displayed with cross hairs on top of thematic layer, then save map window to image file and import the image to AutoCAD. I use the points on the image to align with the duplicate points in the AutoCAD drawing. I save the drawing and close it, then resave the thematic map, with the points removed, overwriting the existing image. I open the AutoCAD drawing and I have a clean image with just the thematic shading. > > It sounds a bit cumbersome, but I can do this quite quickly, do you think writing the tfw would save any time? > > TIA > > Brian > > -----Original Message----- > From: B.
