DXGI_GAMMA_CONTROL_CAPABILITIES

構造体
サイズx64: 4116 バイト / x86: 4116 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x64x86説明
ScaleAndOffsetSupportedBOOL4+0+0スケールとオフセットの調整に対応するかを示すブール値。
MaxConvertedValueFLOAT4+4+4変換後に取り得る最大値。
MinConvertedValueFLOAT4+8+8変換後に取り得る最小値。
NumGammaControlPointsDWORD4+12+12ガンマ制御点の数。
ControlPointPositionsFLOAT4100+16+16各ガンマ制御点の位置を表す配列。

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)
; DXGI_GAMMA_CONTROL_CAPABILITIES サイズ: 4116 バイト(x64)
dim st, 1029    ; 4byte整数×1029(構造体サイズ 4116 / 4 切り上げ)
; ScaleAndOffsetSupported : BOOL (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; MaxConvertedValue : FLOAT (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; MinConvertedValue : FLOAT (+8, 4byte)  st.2 = 値  /  値 = st.2   (lpoke/lpeek も可)
; NumGammaControlPoints : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; ControlPointPositions : FLOAT (+16, 4100byte)  varptr(st)+16 を基点に操作(4100byte:入れ子/配列)
; ※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。
