but uncompressed image data.off
- the starting offset of the data to be written in the
array b
.width
- the width of the rectangle of pixels to be written.height

- an array of int
s indicting
the number of bits used to represent each image sample within
a pixel.scanlineStride
- the number of bytes separating each
row of the input data.IOException
- if the supplied data cannot be encoded by
