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 |
