hello,
i am performing the scalling operation on the 1 bit tiff file.To get speed i
am implementing the TiledImage.using the tilecache memory i am getting the
desired speed while scaling operation.
while scalling operation,image got blurred.so to get the original quality
while scalling operation i am implementing the "subsampleBinaryToGray"
operation.my image has property,
pixelbit: 1
colormodel : indexcolormodel
sample model: MultiPixelPackedSampleModel
now my problem is that when i am performing the scaling operation i got the
desired quality bt caching is not doing properly.Number of tile count will
be less and Caching of the tile is not doing while scalling
operation.tileCache memory is not used while scalling operation.so the speed
is decreased.
can any one give me advice to slove my problem?

waiting for reply,
Sonal.
