Witryna12 paź 2024 · My guess is the following: first the 32 bit float is cast to 8 bit signed integer, which defaults to truncating towards zero, ex. -1.3 becomes -1. Then a cast from unsigned 8 bit integer to 8 bit unsigned integer, giving a value of 255. Something like float x = -1.2997805; # Assume float is 32-bit (uint8_t) (int8_t)x; Witrynaimshow を使用して、フィルター処理されたイメージを既定の表示範囲で表示します。データ型 double のイメージの場合、既定の表示範囲は [0, 1] です。フィルター処理されたピクセル値が範囲 [0, 1] を越えているため、イメージは黒と白で表示されます。 inflated concrete homes
