Unless i am misunderstanding what your saying...
You can not cut a jpg. There is no cuttable data there.
You need to trace it to produce the lines a plotter needs to cut.
Unless i am misunderstanding what your saying...I'm using Sign blazer elements software and can't seem to get a jpeg file to import and cut . Looks good on the page and is a true jpeg or png file , but cuter says it is bitmap
any ideas ?
