Add tools/gen_skin_template.py to generate a labeled 642x420 PNG template for creating custom spritesheets. Move rg35xx device scripts from tools/ to device/rg35xx/. Point prev_sprite at its own cell (bottom-center) so Prev and Next can have distinct icons. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

gen_skin_template.py — Generate a skin template PNG for sdlamp2.
|
|
|
|
Creates a 642x420 PNG showing the sprite grid layout with labeled gutters.
|
|
Each 200x200 cell is blank white (ready to draw on). The 20px gutters between
|
|
cells are gray with small text labels identifying adjacent cells.
|
|
|
|
Grid layout:
|
|
Col 0 (0-199) Col 1 (220-419) Col 2 (440-639)
|
|
Row 0: REWIND PLAY FF
|
|
----gutter y=200-219 with labels----
|
|
Row 1: STOP PREV NEXT
|
|
|
|
Two extra pixels on the right (640-641) are gutter fill to reach 642px width,
|
|
matching the spritesheet dimensions.
|
|
|
|
Usage: python3 tools/gen_skin_template.py [output.png]
|
|
|
|
Requires Pillow.
