问题描述
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)
