+
+- Convert a PAM image to a TIFF image:
+
+`pamtotiff {{path/to/input_file.pam}} > {{path/to/output_file.tiff}}`
+
+- Explicitly specify a compression method for the output file:
+
+`pamtotiff -{{none|packbits|lzw|g3|g4|flate|adobeflate}} {{path/to/input_file.pam}} > {{path/to/output_file.tiff}}`
+
+- Always produce a color TIFF image, even if the input image is greyscale:
+
+`pamtotiff -color {{path/to/input_file.pam}} > {{path/to/output_file.tiff}}`
