LATTICE_METRICS

構造体

サイズx64: 20 バイト / x86: 20 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	型	サイズ	x64	x86	説明
lsBaseline	LINE_SEGMENT	16	+0	+0	文字の基線を表す線分(LINE_SEGMENT)。
iMidlineOffset	SHORT	2	+16	+16	基線からの中線オフセット値。

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)
; LATTICE_METRICS 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)
; lsBaseline : LINE_SEGMENT (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; iMidlineOffset : SHORT (+16, 2byte)  wpoke st,16,値  /  値 = wpeek(st,16)
; ※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)。
