    1.30 +-------
    1.31 +
    1.32 +  * -t 128 : will set the transparency threshold level as 128, so pixels with
    1.33 +    alpha level less than 128 will become fully transparent.
    1.34 +  * -b "#ff0000" -b 255 0 0 : will set the background color as red, so
    1.35 +    partially transparent pixels will be composed over red.
    1.36 +    When -b is used, -t is ignored.
    1.37 +
    1.38 +When no options are specified, default threshold is 128, no background color.
