Hello everybody,

i am wanna read a large 1 bit tiff-file. My problem is to read the file
with
tiffopen an then get the data with TIFFReadRGBAImage in a raster.
Now i can get with TIFFGetR/TIFFGetG/TIFFGetB/TIFFGetA one pixel,
but how to set a Pixel?
Second Problem:
The _tiffmalloc for the raster (where TIFFReadRGBAImage sets the date)
fails because of not enought memory. Is there a way to read a tiff-file and
get the value of one specific pixel in the bitmap and set the value of one
specific pixel in a bitmap?

tia,
     Stephan
