Scanned .TIF files

 Greetings !

I have some files generated by the Company scanner, which decides for itself whether to produce .JPGs or .TIFs.

The .TIF files (of hand-written notes) comprise only black pixels on a white background, and the entire area is covered in these dots, at different densities, closer together to represent text.

How can I fill in the white background to make solid lines, AND eliminate the scattered black dots elsewhere ?

"De-speckle" OUGHT to do it - but it doesn't !

I have had an error: "Internal program error: An invalid parameter has been passed to a function."

"Salt-&-Pepper" does away with the dots in the white area, but doesn't fill in between the black dots.

What is required is a routine that, given a Radius, investigates each pixel in turn, and if it is black, puts a black line between it and every other black pixel within the given Radius. Or something like that !

 

Any ideas, Please ?

  • Your scanner is kicking in at 1 bit black and white for the text, as if it was setting up to send a fax (Is it an "All-in-One scanner / printer ?) probbaly because it does not "see" any colour variation ( if the text was all in red, it might do the same thing). You say the copier chooses automatically. There must be some way to overide that. Other than text faxing, I can't see any benefit to a dot matrix type scan.
     
    What type of scanner is it ?
