"""Generate the ThreadCount Staff launcher icon.
|
|
|
|
python3 scripts/make-staff-icon.py
|
|
|
|
The two apps have to be the same family and still be telling apart on a home screen, where the
|
|
only other clue is a truncated label. So this is the counter app's mark exactly — four stepped
|
|
bars in the 60/48/34/22 proportions from tc-icon.svg — inverted onto ink: the leading bar keeps
|
|
the accent, the rest go from ink to paper, and the ground goes from paper to ink.
|
|
|
|
Light tile versus dark tile is the strongest difference available at 48px, it costs no new
|
|
artwork, and it stays on-brand: the app's own splash is already ink.
|
|
|
|
The geometry is measured from the counter app's own PNGs rather than guessed, and expressed as
|
|
fractions of the canvas so every density comes out identical rather than merely similar. Bars are
|
|
drawn at 4x and downsampled, which is what keeps a 43-pixel-wide bar from landing half a pixel
|
|
off at mdpi.
