DWRITE_LINE_METRICS1

構造体

サイズx64: 32 バイト / x86: 32 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	x64	x86	説明
Base	DWRITE_LINE_METRICS	24	+0	+0	基本行メトリクス(DWRITE_LINE_METRICS)を埋め込んだ構造体。
leadingBefore	FLOAT	4	+24	+24	行の前(上)に追加される行間スペースをDIP単位で表す値。
leadingAfter	FLOAT	4	+28	+28	行の後(下)に追加される行間スペースをDIP単位で表す値。

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)
; DWRITE_LINE_METRICS1 サイズ: 32 バイト(x64)
dim st, 8    ; 4byte整数×8(構造体サイズ 32 / 4 切り上げ)
; Base : DWRITE_LINE_METRICS (+0, 24byte)  varptr(st)+0 を基点に操作(24byte:入れ子/配列)
; leadingBefore : FLOAT (+24, 4byte)  st.6 = 値  /  値 = st.6   (lpoke/lpeek も可)
; leadingAfter : FLOAT (+28, 4byte)  st.7 = 値  /  値 = st.7   (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。
; ※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)。
