Hi,
   Still some problems with rle encoder.
As in tiff/sgi, the lower 7 bits of the Repetition Count specify the
real consecutive pixels MINUS 1(a value of 0 implies 1 pixel while a
value of 0x7F implies 128 pixels). So in rle.c we count up to 128
pixels. In SGI, this byte simply means just the consecutive bytes, so
the maximun number of it is 127. I wonder if it is wise to modify the
rle.c again and set the consecutive pixels upper bound to a configurable
parameter?
