**Scanner le QR à l'écran** (bouton QR du champ 2FA de l'éditeur, 2026-09-18) :
|
||||||
|
`cmd://qr/screen` → la fenêtre passe au tray, `PM.ScreenQr` capture **tout le
|
||||||
|
bureau virtuel** en mémoire (GDI, octets bruts, jamais sur disque) et le décode
|
||||||
|
par ZXing.Delphi — le même que l'APK, `android-client\ThirdParty\ZXing` dans le
|
||||||
|
chemin de recherche du `.dproj`. Pas de sélection de zone : le décodeur trouve
|
||||||
|
le QR où qu'il soit. **Seul un `otpauth://` repart vers la page**
|
||||||
|
(`Bridge.onScreenQr`), le reste de l'écran ne quitte pas l'exe. Format `BGR32`
|
||||||
|
et non `BGRA32` : l'octet alpha d'une capture GDI vaut 0, lu comme transparent
|
||||||
|
→ image blanche.
