#1.はじめに

GIMP Python-Fuでイラストを描くその3 全身編 - Qiitaの続きです。ハイライトと影を追加しました。
GIMP 2.10で動作確認をしています。

#2.実行結果

50%縮小表示です。原寸はpixivに載せています。
「ブラシで描画」を選択した場合の実行結果です。「鉛筆で描画」の場合には若干結果が変わります。
追記：レイヤーをマージする時に鎖骨が消えていたのを修正しました。

#3.スクリプト変更部分・主要部分

ブラシを自動で選択するようにしました。但し、「鉛筆で描画」を「ブラシで描画」に切り替えることができないため、実行前に「ブラシで描画」を選択しておく必要があります。
「2. Hardness 050」(51x51)は胸のハイライトに、「1. Pixel」(3x3)はそれ以外の全てに使用しています。

    # ブラシ「1. Pixel」(3x3)を選択。「ブラシで描画」に切り替えることはできないので事前に変更して下さい。
    pdb.gimp_context_set_brush("1. Pixel")

    # ブラシ「2. Hardness 050」(51x51)を選択
    pdb.gimp_context_set_brush("2. Hardness 050")

レイヤーグループを画像(トップレベル)に追加する関数です。体と水着のレイヤーグループをメイン関数で作成しています。

# レイヤーグループを画像に追加する
def add_layer_group(image, name):
    layer_group = pdb.gimp_layer_group_new(image)
    image.add_layer(layer_group, 0)
    layer_group.name = name
    return layer_group

子レイヤーをレイヤーグループに追加する関数です。

# 子レイヤーをレイヤーグループに追加する
def add_child_layer_transparent(image, parent_group, name):
    # レイヤーの作成に必要なパラメータ
    width   = image.width
    height  = image.height
    type    = RGBA_IMAGE
    opacity = 100
    mode    = NORMAL_MODE
    #
    # パラメータをもとにレイヤーを作成
    layer = gimp.Layer(image, name, width, height, type, opacity, mode)
    #
    # レイヤーを透明色で塗りつぶす
    layer.fill(TRANSPARENT_FILL)
    #
    # 親レイヤーグループの 0 番目の位置にレイヤーを挿入する
    position = 0
    pdb.gimp_image_insert_layer(image, layer, parent_group, position)
    #
    return layer

メイン関数のレイヤーグループと子レイヤーの作成部分です。

    body_layer_group = add_layer_group(image, "体グループ")
    back_hair_layer = add_child_layer_transparent(image, body_layer_group, "後髪")
    body_layer = add_child_layer_transparent(image, body_layer_group, "体")
    bust_layer = add_child_layer_transparent(image, body_layer_group, "胸")
    face_layer = add_child_layer_transparent(image, body_layer_group, "顔")
    eyes_layer = add_child_layer_transparent(image, body_layer_group, "目")
    bangs_layer = add_child_layer_transparent(image, body_layer_group, "前髪")
    swimsuit_layer_group = add_layer_group(image, "水着グループ")
    swimsuit_waist_layer = add_child_layer_transparent(image, swimsuit_layer_group, "水着ウエスト")
    swimsuit_bust_layer = add_child_layer_transparent(image, swimsuit_layer_group, "水着バスト")

髪のハイライトの描画で、GIMP Python-Fuで不透明部分を選択してマスクを作成する - Qiita、GIMP Python-Fuでマスクを削除する - Qiitaのマスク作成、削除を行って、ハイライトが髪からはみ出さないようにしています。胸の描画でも、胸からハイライトと影がはみ出さないように使用しています。

    # 不透明部分を選択する
    pdb.gimp_image_select_item(image, 0, bangs_layer)
    # 選択範囲からマスクを作成する
    mask = pdb.gimp_layer_create_mask(bangs_layer, ADD_SELECTION_MASK)
    # マスクをレイヤーに追加する

    # マスク編集を無効にする(マスクでない部分を編集する)
    pdb.gimp_layer_set_edit_mask(bangs_layer, FALSE)

    # 髪ハイライト右
    points1 = [

        ]
    make_path_relative(image, points1, 3, TRUE)
    # 髪ハイライト左
    points1 = [

	(300, 330, +10, +30, 0, 0),
        ]
    make_path_relative(image, points1, 3, TRUE)
    # マスクをレイヤーから削除する
    pdb.gimp_layer_remove_mask(bangs_layer, MASK_APPLY)

胸レイヤーをすぐ下の体レイヤーと統合しています。この後に元のbody_layerを使用するとエラーになるので、new_body_layerを使用する必要があります。統合した後に首の影を描画しています。

    # 胸レイヤーをすぐ下の体レイヤーと統合する
    new_body_layer = pdb.gimp_image_merge_down(image, bust_layer, EXPAND_AS_NECESSARY)
