The 'basename' is the first part of the filename that your +textures will use when your mod is done, which should almost always be +the same as the one-word name of your mod. For example, if you supply +the word 'mymod', this script will produce filenames like mymod_red.jpg +or 'mymod_dark_blue_s50.jpg'. The texture that this script will read +and recolor is derived from this parameter, and will be of the form +'basename_base.jpg', i.e. 'mymod_base.jpg'. \nYou can also supply an +overlay image filename. This image needs to be a .png or .gif or some +other alpha-capable format supported by ImageMagick, and will be +composited onto the output files after they have been colorized, but +without being modified. This is useful when you have some part of your +base image that will either get changed undesirably (for example, the +mortar among several bricks, or the shading detail of a stone pattern). +Simply draw two images: one containing the whole image to be colored, +and one containing the parts that should not be changed, with either +full or partial alpha transparency where the re-colored base image +should show through. Skilled use of color and alpha on this overlay can +lead to some interesting effects. \nIf you add '-t' as the first +parameter, the script will switch to 'tint overlay' mode. For this mode +to work, you must also supply the base name as usual, and you must +include an overlay image filename. Rather than re-color the base +texture, the script will alter the hue/saturation/value of the overlay +texture file instead, and leave the base texture unchanged. When using +this mode, the base texture should be drawn in some neutral color, but +any color is fine if it results in what you wanted.\n" + + + exit 1 +} fi + +if [[ ! -e $BASE"_base.jpg" ]]; then { + echo -e "\nThe basename '"$BASE"_base.jpg' was not found." + echo -e "\nAborting.\n" + exit 1 +} fi + +if [[ ! -z $COMPOSITE && ! -e $COMPOSITE ]]; then { + echo -e "\nThe requested composite file '"$COMPOSITE"' was not found." + echo -e "\nAborting.\n" + exit 1 +} fi + +convert $BASE"_base.jpg" -modulate 1,2,3 tempfile.jpg 1>/dev/null 2>/dev/null + +if (( $? )) ; then { + echo -e "\nImagemagick failed while testing the base texture file." + echo -e "\nEither the base file '"$BASE"_base.jpg' isn't an image," + echo "or it is broken, or Imagemagick itself just didn't work." + echo -e "\nPlease check and correct your base image and try again." + echo -e "\nAborting.\n" + exit 1 +} fi + +if [ ! -z $COMPOSITE ] ; then { + convert $BASE"_base.jpg" -modulate 1,2,3 $COMPOSITE -composite tempfile.jpg 1>/dev/null 2>/dev/null + + if (( $? )) ; then { + echo -e "\nImagemagick failed while testing the composite file." + echo -e "\nEither the composite file '"$COMPOSITE"' isn't an image" + echo "or it is broken, or Imagemagick itself just didn't work." + echo -e "\nPlease check and correct your composite image and try again." + echo -e "\nAborting.\n" + exit 1 + } fi +} fi + +rm tempfile.jpg + +base_colors="red orange yellow lime green aqua cyan skyblue blue violet magenta redviolet" + +echo -e -n "\nGenerating filenames based on "$BASE"_base.jpg" +if [ ! -z $COMPOSITE ] ; then { + echo "," + echo -n "using "$COMPOSITE" as an overlay" +} fi + +if [ ! -z $TINT_OVERLAY ] ; then { + echo "," + echo -n "and tinting the overlay instead of the base texture" +} fi + +echo -e "...\n" + +mkdir -p generated-textures + +function generate_texture () { + name=$1 + h=$2 + s=$3 + v=$4 + if [ -z $TINT_OVERLAY ]; then { + if [ -z $COMPOSITE ]; then { + convert $BASE"_base.jpg" -modulate $v,$s,$h -quality 97 "generated-textures/"$BASE"_"$name".jpg" + } else { + convert $BASE"_base.jpg" -modulate $v,$s,$h -quality 97 $COMPOSITE -composite "generated-textures/"$BASE"_"$name".jpg" + } fi + } else { + convert $COMPOSITE -modulate $v,$s,$h -quality 97 MIFF:- | composite MIFF:- $BASE"_base.jpg" "generated-textures/"$BASE"_"$name".jpg" + } fi +} + +hue=0 +for color_name in $base_colors ; do + hue2=`echo "scale=10; ("$hue"*200/360)+100" |bc` + echo $color_name "("$hue" degrees)" + echo " dark" + generate_texture "dark_"$color_name $hue2 100 33 + echo " medium" + generate_texture "medium_"$color_name $hue2 100 66 + echo " full" + generate_texture $color_name $hue2 100 100 + echo " light" + generate_texture "light_"$color_name $hue2 100 150 + echo " dark, 50% saturation" + generate_texture "dark_"$color_name"_s50" $hue2 50 33 + echo " medium, 50% saturation" + generate_texture "medium_"$color_name"_s50" $hue2 50 66 + echo " full, 50% saturation" + generate_texture $color_name"_s50" $hue2 50 100 + hue=$((hue+30)) +done + +echo "greyscales" +echo " black" +generate_texture black 0 0 15 +echo " dark grey" +generate_texture darkgrey 0 0 50 +echo " medium grey" +generate_texture grey 0 0 100 +echo " light grey" +generate_texture lightgrey 0 0 150 +echo " white" +generate_texture white 0 0 190 |
