AMVPDIMINFO
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 |
|---|---|---|---|---|---|
| dwFieldWidth | DWORD | 4 | +0 | +0 | ビデオフィールドの幅をピクセル単位で示す。 |
| dwFieldHeight | DWORD | 4 | +4 | +4 | ビデオフィールドの高さをピクセル単位で示す。 |
| dwVBIWidth | DWORD | 4 | +8 | +8 | 垂直帰線区間(VBI)データの幅をピクセル単位で示す。 |
| dwVBIHeight | DWORD | 4 | +12 | +12 | 垂直帰線区間(VBI)データの高さをピクセル単位で示す。 |
| rcValidRegion | RECT | 16 | +16 | +16 | 有効なビデオデータ領域を示すRECT構造体。 |

}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)
; AMVPDIMINFO 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)
; dwFieldWidth : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; dwFieldHeight : DWORD (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; dwVBIWidth : DWORD (+8, 4byte) st.2 = 値 / 値 = st.2 (lpoke/lpeek も可)
; dwVBIHeight : DWORD (+12, 4byte) st.3 = 値 / 値 = st.3 (lpoke/lpeek も可)
; rcValidRegion : RECT (+16, 16byte) varptr(st)+16 を基点に操作(16byte: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)。
