EMRSETVIEWPORTEXTEX
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 |
|---|---|---|---|---|---|
| emr | EMR | 8 | +0 | +0 | 共通レコードヘッダを表すEMR構造体。 |
| szlExtent | SIZE | 8 | +8 | +8 | 設定するビューポートの範囲(幅と高さ)を表すSIZE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)
; EMRSETVIEWPORTEXTEX サイズ: 16 バイト(x64)
dim st, 4 ; 4byte整数×4(構造体サイズ 16 / 4 切り上げ)
; emr : EMR (+0, 8byte) varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; szlExtent : SIZE (+8, 8byte) varptr(st)+8 を基点に操作(8byte: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)。
