MAIN

テンプレートとなるpptxを読み込み，レイアウトを指定して，スライドを作成する．

prs = Presentation(temprate_pptx_address) slide_layout = search_layout(prs, layout_name) # 「レイアウト名の変更」を参照すること slide = prs.slides.add_slide(slide_layout)

shapes確認用テスト関数

show_shapes_in_slide(ppteset_slide)

show_shapes_in_slide(slide)

作成したスライドのPlaceholderを取得．Placeholder上のtextで探索している．

title_ph = slide.shapes.title graph_ph = search_slideplaceholder(slide, "graph") table_ph = search_slideplaceholder(slide, "table")

グラフを作成し，画像ファイルとして保存，画像ファイルをスライドに挿入．

make_graph() graph_ph.insert_picture('./temp/temp_graph.png') os.remove('./temp/temp_graph.png')

df = make_table()

表プレースホルダーにデータフレームの内容を挿入

graphic_frame = table_ph.insert_table(rows=df.shape[0]+1, cols=df.shape[1]) table = graphic_frame.table # GraphicFrameからTableオブジェクトを取得

ヘッダー行の追加

for col_index, col_name in enumerate(df.columns): table.cell(0, col_index).text = col_name

データ行の追加

for row_index, row in df.iterrows(): for col_index, item in enumerate(row): table.cell(row_index + 1, col_index).text = str(item)

作成したスライドを保存

prs.save('./output/test.pptx')
