"""One-time ROI calibration.
|
|
|
|
Usage:
|
|
python calibrate.py samples/full_1080p.png # interactive: drag 10 slot boxes
|
|
python calibrate.py samples/full_1080p.png --check # draw current config on image
|
|
|
|
Interactive mode: for each of the 10 hero slots (any order), drag a box around
|
|
the portrait (include the whole parallelogram, exclude neighbors), then press
|
|
SPACE/ENTER. Press ESC when all 10 are done. Slots are sorted left-to-right
|
|
and stored as resolution-independent relative coordinates.
