A nibble has 4 bits (although it doesn't have to). While i know how to copy one bit from one byte to another (as explained here: 1101 0000 0000 0000 0000 0000 0100 0000 i.
You mentioned that you can replace anywhere from 0 to 8 nibbles. I have a predefined function with this. No = 77 77 in binary [32 bits] :
A lot depends on how your flexible you are in accepting the nibble list index[4] in your case. 0000 0000 0000 0000 0000 0000 0100 1101 i have to swap first and last nibble: You do still need to mask away the high bit (s) since having the msb set in the. Link), i have a problem for a full 4 bit shift from one byte to another byte from a different array.
语法 nibble (in_raster, in_mask_raster, {nibble_values}) 3/3 代码实例 nibble 示例 1(python 窗口) 此例使用由输入栅格的最邻近点确定的值来替换由输入掩膜所识别的像元。. 选中图案,点击【switching to drawing orthogonal polygons】,在点击【nibble portions out of selected objects】,就可以画出图示的形状进行切除,这里确认是【右键】。 Write a function that swaps the highest bits in each nibble of the byte pointed to by the pointer b. I'll always need to read both nibbles, but will need to write each nibble individually.
