Hi folks, I am currently working with BW PngFiles. I use READ_PNG command to read the png file. Then I try to convert data into double precision for some data analysis. It is not working as I expected. The maximum value seem to be about 3 to 8? I see that READ_PNG is reading the file a UINT [Unsigned Integer: A 16-bit unsigned integer ranging from 0 to 65535]. But when I convert UINT to DOUBLE , I am getting only values in single digits??? Can any one help on item? thank Ramji Digumarthi
