Yes we do. This raster is created here in the ImageWriter as follows
// Create an appropriate 1-line databuffer for writing
int lineSize = sourceWidth*numBandsUsed;
DataBufferByte buffer = new DataBufferByte(lineSize);
// Create a raster from that
int [] bandOffs = JPEG.bandOffsets[numBandsUsed-1];
raster = Raster.createInterleavedRaster(buffer,
sourceWidth, 1,
lineSize,
numBandsUsed,
bandOffs,
null);
