hi all:

     When I resized( actually shrinked it) a GIF using C++ interface, I got
an output much larger than the original.
I noticed that the output image's platte is 256, and I think it's the
reason.(I am sure I compiled tiff with lzw.）

     So I must first use 'sample' to resize and then 'quantizeColors' and
'quantize' to reduce the colors to get a smaller
output. But 'quantize' introduces a much longer time.

     How can I resize a GIF and avoid using 'quantize' to get an output
image with the original platte?
thanks a lot.
