I made in Photo Shop a pcb. I then isolated the lines and the holes and saved them as lines.bmp and holes.bmp. I had no problem converting the lines to a .dxf file using Vextractor but that program can not deal with the small black dots on the white background. I tried another program, WinTopo, and it made small squares from the dots but that is not the problem. The problem is that it doesn't make it in the right scale. I tried PDF2DXF and it has the problem that both other program have. How can I make a drill file from a .bmp or .pdf?
