I have an application for which I am considering the use of Sanselan to process
GeoTIFF images, but am unsure how to use the API to support one of my
requirements.
The main Sanselan class provides an API that reads the TIFF and produces a
BufferedImage. But my need is to get at the raw pixels in a random-access sort
of pattern. While I could just use the BufferedImage.getRGB method to read
pixels, I was wondering if there was a way to "cut out the middle man" and get
at the pixel data directly (the hope being that doing so would improve the time
required to load and process the images). I've been looking through the
Sanselan source code (the documentation is a bit sparse), but am having a bit
of trouble figuring out the best way to proceed.
Does anyone have an example snippet of code or white paper explaining how to do
this? Is it even possible?
