Convert TIF to TNS

In most cases, tif to tns conversion seems represents attempts to transfer pictures (.tif, .gif, .png etc.) to TI-Nspire devices, which are graphing calculators developed by Texas Instruments. It seems that only certain pixel sizes of the pictures can be transferred, so you may need to resize the file first.

There seems to exist program provided by TI that allow users to transfer texts, pictures and other documents to your calculator devices. You can also possibly find small utilities on fan Nspire sites that offer various forms of conversions for transferring of files to calculators.
