More robust support for 1, 2 and 4 bit images

Blocked By: Blocking:


1, 2 and 4 bit images are currently supported, but not in the most flexible way. Instead of storing these images in their original bit depth, we automatically convert them to 8 bit data and throw away the original bit depth. We should do the following:

  • use the type BufferedImage.TYPE_BYTE_BINARY when constructing BufferedImages
  • add a new flag to the API to toggle how openBytes handles < 8 bit data - developers can choose whether to get original data (e.g. 1 byte represents 8 pixels), or expanded data (i.e. 1 byte represents 1 pixel)
  • potentially add new pixel types to the OME data model (uint1, uint2, uint4, etc.)
  • update the TIFF writer to export 1, 2 and 4 bit data
