Hi folks,
taking a short break from trying to remove backlash, I wanted to turn to something simpler...
I want to do some engraving of of Japanese characters, so I had some written and scanned scanned that. The image had grey zones (folds in the paper), so wrote a small python program to decide if a grey was a black or a white, then removed all the blacks that were not an "edge" of the picture - so I have now the outline of the character - neat.
now I could easily "read" that image and generate a long list of coordinates that need to be drilled - x,y pixels. But this would look bad - the spindle would move at x=0 from y=0 to y=end and drill every black pixel on that line, then do x=1 and y=0 to end and drill the pixels on that line... etc, rather like an old TV. This would look quite bad, especially given the backlash I have
What I need is all these pixels to be joined by a single line (okay, several as the lines don't always intersect in "holes", such as in the letter "O") that can be then drilled as a curve - any ideas of how I could do that?? I am sure there are programs that take a list of coordinates, finds the function that goes throught the points - that is what I need I guess!
If anyone is interested in sending me some picture files to see the output, please feel free! High contrast will give better results - see examples attached
many thanks
Thomas
