作为我正在制作的图像识别程序的一部分，我需要将.ps文件转换为.png文件.我知道我可以使用Ghostscript或其他程序，但是有人可以举一个具体的例子来写这样的东西吗:

I need to convert .ps files to .png files as part of an image recognition program I am making. I know I can use Ghostscript or other programs, but could someone give a specific example of how to write something like this:

def ps_to_png(ps_file): file = ghostscript.read(ps_file) png_file = ghostscript.save(file, "png") return png_file

(此代码是伪代码，我想知道如何编写实际执行此代码看起来将要执行的操作的代码.)提前致谢！Stack是一个很棒的社区，我对此表示赞赏.

(This code is pseudo code- I want to know how to write something that actually does what this code looks like it will do.) Thanks in advance! Stack is a great community and I appreciate it.

编辑(尝试的解决方案):在运行此行时:

EDIT (Attempted solutions): When running this line:

os.system("ghostscript file.ps file.png")

我收到以下错误消息:

'ghostscript' is not recognized as an internal or external command, operable program or batch file.

尝试使用枕头时:

from PIL import Image def convert_to_png(ps_file): img = Image.open(ps_file) img.save("img.png")

我收到以下错误:

OSError: Unable to locate Ghostscript on paths

推荐答案

您可以使用枕头.

from PIL import Image psimage=Image.open('myImage.ps') psimage.save('myImage.png')

如果要将其包装到函数中:

If you want to wrap it to a function:

from PIL import Image def convert_to_png(path): img = Image.open(path) img.save("img.png") path='/path_to_your_file' convert_to_png(path)
