I want to be able to export to Uncompressed 8- bit (ie grayscale balck/white) image. Ie GeoTIFF:
Standard:: TIFF File
Format:: Byte integers (8bits)

Using Palette24-bit RGB Image gives uncompressed image, but color so it takes a lot more space than 8-bit. Grayscale Palette gives grayscale but it is compressed and I need uncompressed.

    This could be possible, but I'm curious why you would need uncompressed grayscale. The compressed version is still lossless, so you don't lose anything by using compression and you gain a lot in saved disk space.

    Thanks,

    I didn`t know that the compressed version was lossless, but examining the picture you are correct. However I am worried about compatibility with different software. I`m not sure if all software will read the files generated. Does any of the forum- readers know about compatibility issues with this formats?
