Hi Jürgen,

if it doesn't have to be TIFF you can use the picture functions to save JPEG/PNG/BMP formats...

Hi Jurgen,

There is no LabVIEW VI that reads or writes TIFF files unless you purchase the NI Vision Development Module.
Otherwise you can do several things:

1. Create BMP/JPEG/PNG file and then convert it to a TIFF file by using a standard image editing software such as Adobe Photoshop.
2. Use the Univesity of Cambridge custom LabVIEW library for reading a TIFF file called Tiff_reader.llb
3. Use LabVIEW 3.1 archived VIs tiffwrit.zip that can be found at Info-LabVIEW.org
4. Look at this related discussion forum.

Let me know if any of those work for you.
Hope this helps!

If you have experience in reading file format specifications, it may not be very hard to write a TIF writer for your specific image type. See TIF specifications from example here:

Of course a 2D array is not yet a picture in any format. 😉

You need additional information, e.g.:

1. What is the representation of the array elements?
2. Is each an integer corresponding to a 24bit color?
3. Is each element an index into a color table?
4. If so, where is the color table?
5. Is it a boolean array that represents a B&W picture?
6. ...

So, where did the 2D array come from?
