anyone interested in high-res performance charts?

The charts look very nice. Do you reenter them? They are too good to
have been scanned in. I'm always interested in the Warrior II and C-172.
W&B charts are most important. Thanks.

"Vectorizing" means that he is taking the original charts and essentially
redrawing them, using a vector-based description (that is, rather than
drawing the charts in a manner similar to painting or printing, the charts
are described as lines from one point to another).

Google "raster versus vector" for more info. The bottom line is that the
resolution of the displayed chart is matched to whatever medium they are
being displayed on. Only the endpoints of each line used to describe the
chart are stored (ie vector data), and during display the actual raster data
required to show the charts on the chosen medium (computer screen, printed
page, etc) is derived from that vector data to match the resolution of the
raster device being used.

So, yes...they are necessarily "reentered" and not scanned (that is, they
may have been scanned as part of the vectorization process, but the end
result you're seeing is not the scan itself).
