Gimp python-fu :如何从1jpg和1png创建和保存多层xcf？

Gimp python-fu是GIMP（GNU Image Manipulation Program）的Python插件系统，它允许开发者使用Python编写脚本来扩展GIMP的功能。通过Gimp python-fu，我们可以实现从1jpg和1png创建和保存多层xcf的操作。

具体步骤如下：

导入必要的模块和函数：

from gimpfu import *

定义一个函数来执行创建和保存多层xcf的操作：

def create_and_save_xcf(jpg_path, png_path, xcf_path):
    # 打开jpg和png图像
    jpg_image = pdb.gimp_file_load(jpg_path, jpg_path)
    png_image = pdb.gimp_file_load(png_path, png_path)
    
    # 创建一个新的xcf图像
    xcf_image = pdb.gimp_image_new(jpg_image.width, jpg_image.height, RGB)
    
    # 将jpg和png图层添加到xcf图像中
    jpg_layer = pdb.gimp_image_merge_visible_layers(jpg_image, CLIP_TO_IMAGE)
    pdb.gimp_image_insert_layer(xcf_image, jpg_layer, None, 0)
    png_layer = pdb.gimp_image_merge_visible_layers(png_image, CLIP_TO_IMAGE)
    pdb.gimp_image_insert_layer(xcf_image, png_layer, None, 1)
    
    # 保存xcf图像
    pdb.gimp_xcf_save(0, xcf_image, xcf_image.active_layer, xcf_path, xcf_path)
    
    # 关闭所有图像
    pdb.gimp_image_delete(jpg_image)
    pdb.gimp_image_delete(png_image)
    pdb.gimp_image_delete(xcf_image)

注册函数并设置参数：

register(
    "create_and_save_xcf",
    "Create and save multi-layer xcf from jpg and png",
    "Create and save multi-layer xcf from jpg and png",
    "Your Name",
    "Your Name",
    "2022",
    "<Image>/File/Create and Save XCF",
    "*",
    [
        (PF_FILE, "jpg_path", "JPG file", None),
        (PF_FILE, "png_path", "PNG file", None),
        (PF_FILE, "xcf_path", "XCF file", None)
    ],
    [],
    create_and_save_xcf
)
