一次性将多个文件保存为 (GIMP)

Question

我有一系列的.xcf图片，我想保存为.png格式。我可以打开每个文件并另存为.png，但由于图片数量很多，这需要花费相当长的时间。

有没有一种方法可以一次转换所有图片，或者有其他方法可以让我在这项工作上花费更少的时间呢？

提前感谢您的帮助。

Answer 1

我会使用GIMP内置的Python控制台来完成这个任务 - 如果你正在使用Windows系统，请查看如何安装GIMP 2.6的Python扩展（在Linux上，它可能已经被安装或者只需要安装gimp-python包，Mac OS上也可能是同样的方法）。

在GIMP的Python控制台中，您可以通过查看帮助->过程浏览器对话框来访问大量的GIMP API - 除了具有Python的所有其他功能，包括文件和字符串操作。

一旦您进入Python-fu控制台，就可以像这样做：

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 - 将所需目录连接到要处理其他目录的文件路径）。

如果您需要多次执行此操作，请查看随gimp-Python一起提供的示例插件，并将上面的代码粘贴为自己使用的GIMP Python插件的核心。

作为批量转换工具并不是GIMP的核心目标。虽然可以通过第三方脚本来完成，但是对于脚本生态系统的支持还有待提高。 - jsbueno

如果您已安装 imagemagick，则可以这样做：

mogrify -format png *.xcf

这将自动将它们转换到同一目录中。还可以阅读 man mogrify 或者这个链接 查看其他选项。

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）：

      (gimp-file-save RUN-NONINTERACTIVE 
                      image 
                      (car (gimp-image-get-active-layer image)) 
                      (car (gimp-image-get-filename image)) 
                      (car (gimp-image-get-filename image))) 
      (gimp-image-clean-all image) 
      (set! i (- i 1))))) 

(script-fu-register "script-fu-save-all-images" 
 "<Image>/File/Save ALL" 
 "Save all opened images" 
 "Saul Goode" 
 "Saul Goode" 
 "11/21/2006" 
 "" 
 ) 

将文件与相同扩展名放入插件文件夹中(在Windows上是C:\Program Files\GIMP 2\share\gimp\2.0\scripts)。然后您甚至不需要重新启动应用程序。选择“滤镜”菜单->“Script-Fu” ->“更新脚本”。您将在“文件”菜单中（在底部）看到“保存全部”选项。这对我来说非常快速和容易。此脚本来自此处。还有另一个脚本，但我自己没有测试过。

Answer 5

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处理插件[链接1] [存档]。该项目是开源的，可以在GitHub上找到[链接3]。

Answer 6

这个脚本在 Windows 7 的 gimp 2.8 上完美运行。

UCHLIN WILKINSON 从 GIMP 中保存所有打开的图像。

如果您正在扫描大量图像并且只想一次性导出它们，那么这将非常方便。它基于 Saul Goode 的脚本，并扩展了提示图像基本名称、目录等功能。

将其保存为 saveall.scm 并放置在 Gimp 脚本目录中。例如：~/.gimp-2.8/scripts/
