Changes one or more hues in a PNG file (as used when authoring Simutrans paks) to other hues, or to player color gradients or alternate color gradients.
The desired changes are specified as a single comma-separated list, without internal spaces. Each component specifies a source color range, a dash, and a destination (output) color range. Components are of this form:
where only the hue and new_hue are required. Tolerance defaults to 10. The forced saturation is ignored when the output is set to player or alternate gradients.
The following switches are available:
-i <input file> -o <output file> -p <paksize> -x <crop single X offset> -y <crop single y offset> -M lists the hues of all (bright) mapcolors [7, 15, etc.] and exits -v Verbose. Primarily prints an explanation of how the components in the change-list were parsed.
./alter_hue -i INFILE -o OUTFILE 20+7-m100,40-180,60-p
(assuming the alter_hue program file has the +x (execute) attribute) which will change:
- hue 20 ± 7 to hue of mapcolor 100,
- hue 40 ± 10 [using the default 10] to hue 180, and
- hue 60 ± 10 to special player colors.
Alternately color map can be, for example:
which would change:
Player color gradation to correspond to range containing mapcolor 70 (i.e., 64..71) and
Alternate player-color gradation to mapcolor 25 (i.e., 24..31).
When converting to player or alternate gradients, an offset level may be specified. A component thus would have the form:
./alter_hue -i INFILE -o OUTFILE 188+5pL30
would convert hue 188, with tolerance of 5, to player gradient, using an offset level of 30. This would have the effect of darkening the output by about 20% compared to the standard transformation.
Note that Hue is specified in the HSV system. If your modifications seemingly have no effect, please verify that your graphic editing program is displaying HSV.
