c# - Bitmap Stride 和 4 bytes 的关系？

Question

这句话是什么意思:

The Stride property, holds the width of one row in bytes. The size of a row however may not be an exact multiple of the pixel size because for efficiency, the system ensures that the data is packed into rows that begin on a four byte boundary and are padded out to a multiple of four bytes.

Answer 1

这意味着如果您的图像宽度为 17 像素并且颜色为 3 个字节，则您将获得 51 个字节。因此，您的图像宽度(以字节为单位)为 51 字节，那么步长为 52 字节，这是图像宽度(以字节为单位)四舍五入到下一个 4 字节边界。
