KSCAMERA_EXTENDEDPROP_ROI_INFO
構造体サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。
フィールド
| フィールド | 型 | サイズ | x64 | x86 | 説明 |
|---|---|---|---|---|---|
| Region | RECT | 16 | +0 | +0 | ROIの矩形領域を表すRECT(正規化座標)。 |
| Flags | ULONGLONG | 8 | +16 | +16 | ROIの状態や動作を示す64ビットフラグ。 |
| Weight | INT | 4 | +24 | +24 | ROIの重み(優先度)を示す。 |
| RegionOfInterestType | INT | 4 | +28 | +28 | ROIの種別(顔/被写体など)を示す値。 |

}HSP用 定義
HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。
; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; KSCAMERA_EXTENDEDPROP_ROI_INFO サイズ: 32 バイト(x64)
dim st, 8 ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; Region : RECT (+0, 16byte) varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; Flags : ULONGLONG (+16, 8byte) qpoke st,16,値 / qpeek(st,16) ※IronHSPのみ。3.7/3.8は lpoke st,16,下位 : lpoke st,20,上位
; Weight : INT (+24, 4byte) st.6 = 値 / 値 = st.6 (lpoke/lpeek も可)
; RegionOfInterestType : INT (+28, 4byte) st.7 = 値 / 値 = st.7 (lpoke/lpeek も可)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
