TIFFCompressorImageOutputStream.encode in class TIFFCompressorb - an array of bytes containing the packed
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 - the height of the rectangle of pixels to be written.bitsPerSample - an array of ints 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
this TIFFCompressor, or if any I/O error occurs
during writing.Copyright © 2015–2022 SCIFIO. All rights reserved.
