MFCameraIntrinsic_DistortionModel
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

}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)
; MFCameraIntrinsic_DistortionModel サイズ: 20 バイト(x64)
dim st, 5 ; 4byte整数×5(構造体サイズ 20 / 4 切り上げ)
; Radial_k1 : FLOAT (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; Radial_k2 : FLOAT (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; Radial_k3 : FLOAT (+8, 4byte) st.2 = 値 / 値 = st.2 (lpoke/lpeek も可)
; Tangential_p1 : FLOAT (+12, 4byte) st.3 = 値 / 値 = st.3 (lpoke/lpeek も可)
; Tangential_p2 : FLOAT (+16, 4byte) st.4 = 値 / 値 = st.4 (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。
