EMRARC

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 40 バイト / x86: 40 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)。

フィールド

フィールド型サイズx64x86説明
emrEMR8+0+0共通レコードヘッダを表すEMR構造体。
rclBoxRECTL16+8+8円弧の元となる楕円の外接矩形を表すRECTL構造体。
ptlStartPOINTL8+24+24円弧の開始点を定める座標を表すPOINTL構造体。
ptlEndPOINTL8+32+32円弧の終了点を定める座標を表すPOINTL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)
; EMRARC サイズ: 40 バイト(x64)
dim st, 10    ; 4byte整数×10(構造体サイズ 40 / 4 切り上げ)
; emr : EMR (+0, 8byte)  varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; rclBox : RECTL (+8, 16byte)  varptr(st)+8 を基点に操作(16byte:入れ子/配列)
; ptlStart : POINTL (+24, 8byte)  varptr(st)+24 を基点に操作(8byte:入れ子/配列)
; ptlEnd : POINTL (+32, 8byte)  varptr(st)+32 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)。
