I just recorded the process of mapping LEDs on a photo, in order to explain the use of FreeLED tools to a user named ButerBrott. And here's what i did:

- Upload the photo as background, dimm it for comfortable view of dots
- Use Link (L) tool and Ctrl + Mouse wheels to draw the lower half of the hex
- Then use Copy (Ctrl+C) and Paste (Ctrl+V) to create the upper half as a copy of the lower half
- Then use Flip (FX/FY) to correct the path

- Then use Invert (I) to correct the direction

- Then use Link (L) to connect the 2 halves

Use the tool freely at freeled.org

This online webapp solves most of your 1D 2D (and some 3D) mapping head aches, and exports to various formats, including FastLED arrays.
Check it out r/FreeLED or go directly to the tool which is permanently host at freeled.org
