one of the following lines to the stamp's data file:
Normal tinter — "tinter=normal" (the default)
This is the normal tinting mode. (Hue range is ±18°, 27
replace.)
'Any hue' tinter — "tinter=anyhue"
This remaps all hues in the stamp. (Hue range is ±180°.)
This is the normal tinting mode. First, the primary hue
of the stamp is determined. (For example, a picture of a
flower with a stem will have the petal color seen as the
primary hue of the overall image.) Next, the most highly
saturated part of the picture is found. With "normal
tinter", the range of hue used to do this starts out
within ±18° of the pimary hue found in step 1. (If none
can be found, it widens the range by 50% and tries
again.) Finally, the image is tinted. Anything falling
within 50% of the range (e.g., ±27°) is altered to have
the hue of the color chosen by the user.
Narrow tinter — "tinter=narrow"
This like the "anyhue" option, but with a narrower hue
angle. (Hue range is ±6°, 9 replace.)
This like the "normal" option described above, but
starts a narrower hue range of ±6°. Anything found
within 50% of the range (e.g. ±9°) is tinted. If too
much of your stamp is being tinted, try this option.
'Any hue' tinter — "tinter=anyhue"
This remaps all hues in the stamp. It works similarly to
the "anyhue" and "narrow" options described above, but
the hue range is ±180°.)
Vector tinter — "tinter=vector"
This maps 'black through white' to 'black through
