DWRITE_TEXT_METRICS

構造体

サイズx64: 36 バイト / x86: 36 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
left	FLOAT	4	+0	+0	レイアウト矩形の左端からテキスト描画領域の左端までの距離。
top	FLOAT	4	+4	+4	レイアウト矩形の上端からテキスト描画領域の上端までの距離。
width	FLOAT	4	+8	+8	末尾空白を含まないテキストの幅をDIP単位で表す値。
widthIncludingTrailingWhitespace	FLOAT	4	+12	+12	末尾空白を含むテキストの幅をDIP単位で表す値。
height	FLOAT	4	+16	+16	整形されたテキスト全体の高さをDIP単位で表す値。
layoutWidth	FLOAT	4	+20	+20	テキストレイアウトに割り当てられた最大幅。
layoutHeight	FLOAT	4	+24	+24	テキストレイアウトに割り当てられた最大高さ。
maxBidiReorderingDepth	DWORD	4	+28	+28	双方向(BiDi)並べ替えの最大ネスト深さ。
lineCount	DWORD	4	+32	+32	整形結果に含まれる行の総数。

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_TEXT_METRICS サイズ: 36 バイト(x64)
dim st, 9    ; 4byte整数×9(構造体サイズ 36 / 4 切り上げ)
; left : FLOAT (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)

; width : FLOAT (+8, 4byte)  st.2 = 値  /  値 = st.2   (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。
