Well said DC.
I realize that my explanation (for the process of including a bounding box of a known size in order to set "scale") was a bit brief.
So, when trying to convert a vector based image to a raster based image, for the purpose of engraving, it is good to find out what the highest resolution (dpi) that the goal process can handle.
Working with pixel based software, like photoshop, one has the ability to work in the desired dpi, to crop to an area defined by a bounding box of a predetermined size and then set the size of the remaining image to the prescribed value.
In this way, if the end user imports the bmp or jpg into the engraving software at the highest supported res, then the size of the desired part should come out as close as possible.
