WebSep 3, 2013 · The mask turns the top 8 bits to 0, where the old alpha value was. The alpha value is shifted up to the final bit positions it will take, then it is OR-ed into the masked pixel value. The final result is 0x45345678 which is stored … WebApr 8, 2024 · So we read bits starting with the top bit, and construct the result starting with its MSB. (We left shift 1 bit at a time into the destination with ADD to left shift, and a conditional add to set the new bit position or not.) We can use a 2's complement signed comparison to read the top bit of a register. If it's set, x < 0, otherwise it's not. WebJul 12, 2010 · The bits can be put to another starting bit in the target byte. In this example, I want to copy 3 bits (bitCount=3) from bit #4 (sourceStartBit) to bit #3 (destinationStartBit). Please note that the numbering of bits starts with "0" and that in my method, the numbering starts with the most significant bit = 0 (reading from left to right). in china 1910 youngest parents

WebAnding an integer with 0xFF leaves only the least significant byte. For example, to get the first byte in a short s, you can write s & 0xFF.This is typically referred to as "masking". If byte1 is either a single byte type (like uint8_t) or is already less than 256 (and as a result is all zeroes except for the least significant byte) there is no need to mask out the higher …
