我有一個顏色列表文件我把它讀入一個python列表中，我想創建一個（或幾個）由正方形組成的背景顏色的圖像，顏色的前景html字符串（用白色書寫）。即我從輸入文件中讀取＃ff0000，然後創建一個帶有紅色背景的100x100正方形和一個白色字符串「＃ff0000」作爲前景...等等，以便輸入文件中的每種顏色。python-fu複製圖像
這是我的腳本：

我現在的問題是與方法的drawRect。在drawRect方法中，我無法將createImage方法返回的圖像複製到較大圖像的座標x，y處。在drawRect方法中，我嘗試使用gimp的「複製到選區」：選擇一個區域，並粘貼從其他圖像複製的東西。但是我對圖層有困難，無法將圖像複製到正確的位置。
只是爲了完整性這種從IFC文件的幾行：提前任何幫助
