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)
; DXGI_HDR_METADATA_HDR10 サイズ: 28 バイト(x64)
dim st, 7    ; 4byte整数×7(構造体サイズ 28 / 4 切り上げ)
; RedPrimary : WORD (+0, 4byte)  varptr(st)+0 を基点に操作(4byte:入れ子/配列)
; GreenPrimary : WORD (+4, 4byte)  varptr(st)+4 を基点に操作(4byte:入れ子/配列)
; BluePrimary : WORD (+8, 4byte)  varptr(st)+8 を基点に操作(4byte:入れ子/配列)
; WhitePoint : WORD (+12, 4byte)  varptr(st)+12 を基点に操作(4byte:入れ子/配列)
; MaxMasteringLuminance : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; MinMasteringLuminance : DWORD (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; MaxContentLightLevel : WORD (+24, 2byte)  wpoke st,24,値  /  値 = wpeek(st,24)
; MaxFrameAverageLightLevel : WORD (+26, 2byte)  wpoke st,26,値  /  値 = wpeek(st,26)
; ※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。
