DWRITE_LINE_METRICS
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
| フィールド | 型 | サイズ | x64 | x86 | 説明 |
|---|---|---|---|---|---|
| length | DWORD | 4 | +0 | +0 | 行に含まれるテキストの文字数(末尾空白を除く区分)。 |
| trailingWhitespaceLength | DWORD | 4 | +4 | +4 | 行末の空白文字数。 |
| newlineLength | DWORD | 4 | +8 | +8 | 行末の改行文字が占める文字数。 |
| height | FLOAT | 4 | +12 | +12 | 行の高さをDIP単位で表す値。 |
| baseline | FLOAT | 4 | +16 | +16 | 行の上端からベースラインまでの距離をDIP単位で表す値。 |
| isTrimmed | BOOL | 4 | +20 | +20 | 行が省略(トリミング)されているかを示すブール値。 |

}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_METRICS サイズ: 24 バイト(x64)
dim st, 6 ; 4byte整数×6(構造体サイズ 24 / 4 切り上げ)
; length : DWORD (+0, 4byte) st.0 = 値 / 値 = st.0 (lpoke/lpeek も可)
; trailingWhitespaceLength : DWORD (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; newlineLength : DWORD (+8, 4byte) st.2 = 値 / 値 = st.2 (lpoke/lpeek も可)
; height : FLOAT (+12, 4byte) st.3 = 値 / 値 = st.3 (lpoke/lpeek も可)
; baseline : FLOAT (+16, 4byte) st.4 = 値 / 値 = st.4 (lpoke/lpeek も可)
; isTrimmed : BOOL (+20, 4byte) st.5 = 値 / 値 = st.5 (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。
