问题描述

有人知道如何将DXF文件转换为PNG或PDF吗?

我有一个很大的DXF文件列表,我想将它们转换为图像以便更快地查看它们。

如果可能,如何提取DXF文件值,如DXF文件中该绘图的厚度或尺寸。

import matplotlib.pyplot as plt
import ezdxf
from ezdxf.addons.drawing import RenderContext, Frontend
from ezdxf.addons.drawing.matplotlib import MatplotlibBackend
# import wx
import glob
import re


class DXF2IMG(object):

    default_img_format = '.png'
    default_img_res = 300
    def convert_dxf2img(self, names, img_format=default_img_format, img_res=default_img_res):
        for name in names:
            doc = ezdxf.readfile(name)
            msp = doc.modelspace()
            # Recommended: audit & repair DXF document before rendering
            auditor = doc.audit()
            # The auditor.errors attribute stores severe errors,
            # which *may* raise exceptions when rendering.
            if len(auditor.errors) != 0:
                raise exception("The DXF document is damaged and can't be converted!")
            else :
                fig = plt.figure()
                ax = fig.add_axes([0, 0, 1, 1])
                ctx = RenderContext(doc)
                ctx.set_current_layout(msp)
                ctx.current_layout.set_colors(bg='#FFFFFF')
                out = MatplotlibBackend(ax)
                Frontend(ctx, out).draw_layout(msp, finalize=True)

                img_name = re.findall("(S+).",name)  # select the image name that is the same as the dxf file name
                first_param = ''.join(img_name) + img_format  #concatenate list and string
                fig.savefig(first_param, dpi=img_res)


if __name__ == '__main__':
    first =  DXF2IMG()
    first.convert_dxf2img(['GT-010.DXF'],img_format='.png')
