TLDR
Add text to a PPM image at the specified location
$ ppmlabel -x [pos_x] -y [pos_y] -text [text] [path/to/input_file.ppm] > [path/to/output_file.ppm]
Add multiple texts at different locations
$ ppmlabel -x [pos_x1] -y [pos_y1] -text [text1] -x [pos_x2] -y [pos_y2] -text [text2] [path/to/input_file.ppm] > [path/to/output_file.ppm]
Specify the line color, the background color, the tilt and the size of the added text
$ ppmlabel -x [pos_x] -y [pos_y] -color [line_color] -background [background_color] -angle [tilt] -size [size] -text [text] [path/to/input_file.ppm] > [path/to/output_file.ppm]
