Hello Alan, It is a file having colour data grid.. just like any simple ascii file and i need to manipulate the numbers with colours. But at this stage i am not much bothered with colurs i can associate it with simple RGB value for all different numbers. ex. of such simple file can be like this.. ncols 4 nrows 4 xllcorner 392800 yllcorner 5376340 cellsize 55 NODATA_value -9999 9 3 7 3 8 3 2 7 3 2 1 3 3 7 3 2
and i need to associate each pixel of the image with this data in the ascii... Did that help ?? thanks, Varsha On Nov 12, 2007 1:06 AM, Alan Gauld <[EMAIL PROTECTED]> wrote: > > "Varsha Purohit" <[EMAIL PROTECTED]> wrote > > > In one application i want to convert format of ascii file to > > binary file. > > That depends entirely on what the ASCII file contains. > Is it a comma separated list of RGB values?
