DXGI_MODE_DESC
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 |
|---|---|---|---|---|---|
| Width | DWORD | 4 | +0 | +0 | 表示モードの解像度の幅(ピクセル数)。 |
| Height | DWORD | 4 | +4 | +4 | 表示モードの解像度の高さ(ピクセル数)。 |
| RefreshRate | DXGI_RATIONAL | 8 | +8 | +8 | リフレッシュレートを分数で表すDXGI_RATIONAL。 |
| Format | DXGI_FORMAT | 4 | +16 | +16 | 表示モードのピクセルフォーマットを示す列挙値。 |
| ScanlineOrdering | DXGI_MODE_SCANLINE_ORDER | 4 | +20 | +20 | 走査線の描画順序(プログレッシブ/インターレース)を示す列挙値。 |
| Scaling | DXGI_MODE_SCALING | 4 | +24 | +24 | 解像度がネイティブと異なる場合のスケーリング方式を示す列挙値。 |

}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)
; DXGI_MODE_DESC 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)
; Width : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; Height : DWORD (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; RefreshRate : DXGI_RATIONAL (+8, 8byte) varptr(st)+8 を基点に操作(8byte:入れ子/配列)
; Format : DXGI_FORMAT (+16, 4byte) st.4 = 値 / 値 = st.4 (lpoke/lpeek も可)
; ScanlineOrdering : DXGI_MODE_SCANLINE_ORDER (+20, 4byte) st.5 = 値 / 値 = st.5 (lpoke/lpeek も可)
; Scaling : DXGI_MODE_SCALING (+24, 4byte) st.6 = 値 / 値 = st.6 (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)。
