我有一系列 .xcf 图像，我想将其另存为 .png。我可以打开每个文件并另存为 .png 但由于图像很多，因此需要相当长的时间。
有没有办法一次性转换所有图像，或者有其他方法可以减少我在这项工作上花费的时间？
提前谢谢您。
为此，我会使用 GIMP 内的 Python 控制台 - 如果您碰巧在 Windows 中，请查看如何安装 GIMP 2.6 的 Python 扩展（在 Linux 上，它要么是未安装的，要么是安装 gimp 的问题） python 包，在 Mac OS 上可能相同）
从 GIMP 的 Python 控制台中，您可以访问巨大的 GIMP API，您可以通过查看帮助 -> 程序浏览器对话框进行检查 - 除了具有 Python 的所有其他功能（包括文件和字符串操作）之外。
你是=在Python-fu控制台中，做这样的事情是很重要的：
import glob
for fname in glob.glob("*.xcf"):
img = pdb.gimp_file_load(fname, fname)
img.flatten()
new_name = fname[:-4] + ".png"
pdb.gimp_file_save(img, img.layers[0], new_name, new_name)
（这将在 GIMP 默认使用的目录上工作 - 将 desried 目录连接到文件路径以在其他目录上工作）。
如果您多次需要这样做，请查看 gimp-Python 附带的示例插件，并将上面的代码粘贴为 GIMP 的 python 插件的核心以供您自己使用。
您可以快速创建一个名为 SaveAll 的插件。将此代码保存到扩展名为 .scm 的文件中（例如 saveall.scm）：

将文件放入具有相同扩展名的plugins文件夹中 （在 Windows 上为 C:\Program Files\GIMP 2\share\gimp .0\scripts）。
然后您甚至不必重新启动应用程序。 过滤器菜单 -> Script-Fu -> 更新脚本。您将在 File 菜单（位于最底部）中看到 Save ALL 项目。对我来说它工作起来又快又简单。
这个脚本来自这里。
还有另一个脚本，但我自己没有测试过。
是的，有一种方法，而且不需要编程技能。只需安装免费的批量图像操作插件。

此脚本在
gimp 2.8UCHLIN WILKINSON 保存 GIMP 中所有打开的图像。
如果您正在扫描大量图像并且只想一次性导出它们，这会很方便。它基于 Saul Goode 的脚本，扩展为提示图像基本名称、目录等。
将其保存为 Gimp 脚本目录中的 saveall.scm。例如。 〜/.gimp-2.8/scripts/
