buf.get(0)
would return the pixel information for the
pixel at coordinates (0, 0)
.
The scanlineStride
parameter defines the distance from the pixel
data at the start of one row to the pixel data at the start of the
immediately following row at the next higher Y coordinate. Usually,
scanlineStride
is the same as the width of the image multiplied
by the number of data elements per pixel (1 for the case of the
integer and indexed formats, or 3 or 4 in the case of the byte
formats), but some images may have further padding between rows for
alignment or other purposes.getArgb
