Import Raster To Vector

This command creates polylines from a raster image. The image can be either an external .bmp file or an image inserted in the drawing.

For the external file to process other file types, such as .tif or .jpeg, open the image up in Microsoft Paint and Save As the file as a monochrome .bmp. In the dialog below, you can specify the Layer, Color, Scale, and whether to draw the entities on the screen or write a .dxf file. Minimum Polyline Length will reduce the amount of line segments created from the conversion.

For an image in the drawing, you can process the entire image or limit the area to process by window or inclusion polylines. The Erase Selection option wipes out the image with the specified Backgroudn Color in the area that is processed.
