KSPROPERTY_CAMERACONTROL_REGION_OF_INTEREST_S

構造体
サイズx64: 32 バイト / x86: 32 バイト

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)。

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)
; KSPROPERTY_CAMERACONTROL_REGION_OF_INTEREST_S 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)
; FocusRect : RECT (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; AutoFocusLock : BOOL (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; AutoExposureLock : BOOL (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; AutoWhitebalanceLock : BOOL (+24, 4byte)  st.6 = 値  /  値 = st.6   (lpoke/lpeek も可)
; Anonymous : _Anonymous_e__Union (+28, 4byte)  varptr(st)+28 を基点に操作(4byte:入れ子/配列)
; ※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)。
#defstruct global RECT
    #field int left
    #field int top
    #field int right
    #field int bottom
#endstruct

stdim st, KSPROPERTY_CAMERACONTROL_REGION_OF_INTEREST_S        ; NSTRUCT 変数を確保

mes "AutoFocusLock=" + st->AutoFocusLock
; ※union フィールドは byte 列で確保(NSTRUCT は union 非対応)。必要に応じ手動でアクセス。
