DIPROPCPOINTS

構造体
サイズx64: 84 バイト / x86: 84 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
diphDIPROPHEADER16+0+0プロパティ共通ヘッダー(DIPROPHEADER)。
dwCPointsNumDWORD4+16+16cp配列に含まれるキャリブレーション点の数。
cpCPOINT64+20+20キャリブレーション点(CPOINT)の配列。

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)
; DIPROPCPOINTS サイズ: 84 バイト(x64)
dim st, 21    ; 4byte整数×21(構造体サイズ 84 / 4 切り上げ)
; diph : DIPROPHEADER (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; dwCPointsNum : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; cp : CPOINT (+20, 64byte)  varptr(st)+20 を基点に操作(64byte: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)。
