I am hoping some one in here has done some CNC programing and used Inkscape to vectorise their designs.
I am looking at this SVG specification that Inkscape specifies on their website: Paths — SVG 2
And I have the attached Inkscape svg file that I created by vectorising a .jpg file from DipTrace.
I had to rename it to a .cpp in order to attach it.
I am intending to read this file and reproduce the image in a MS Windows app and then upload custom CNC commands to a CNC device of my own design.
Refer to "<path id="path21"" below (not all of it is there because it is too big)
Now right from the start this file does not follow the standard for paths!
m 14.272381,197.21428......these are clearly absolute coordinates. So 'm' should be 'M'
A bit further on we have m 149.775329,0 V 147.72661 It still does not follow the standard - absolute coordinates with 'm'
Then I find this m -41.31733,42.0513. These are clearly relative coordinates with a 'm'.
So how are you supposed to tell if the coordinates are relative or absolute when they are not adhering the the standard they have specified?
Has anyone else figured out how to read an inkscape file and accurately reproduce the image in it?
