Python如何将DST文件转换为PNG文件？

Question

我到处看了看，看了一些关于py绣花的文档，我很困惑，所以我问这里。有没有可用的包可以使用Python将DST图像转换为PNG图像？在

在图像复制

import pyembroidery
pattern = pyembroidery.read_dst("shamrockin.dst")
pyembroidery.write_png(pattern, 'shamrockin.dst')

错误

pattern = pyembroidery.read_dst("shamrockin.dst",)
File "/home/panacea/Documents/src/easy tailor/EasyTailor/venv/lib/python3.5/site-packages/pyembroidery/PyEmbroidery.py", line 462, in read_dst reader.read(stream, pattern, settings) File "/home/panacea/Documents/src/easy tailor/EasyTailor/venv/lib/python3.5/site-packages/pyembroidery/DstReader.py", line 86, in read dst_read_header(f, out) File "/home/panacea/Documents/src/easy tailor/EasyTailor/venv/lib/python3.5/site-packages/pyembroidery/DstReader.py", line 55, in dst_read_header header_string = header.decode('utf8') UnicodeDecodeError: 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte

Answer 1

将PNG文件写入'shamrockin.dst'，这将覆盖原始文件。第二次运行时，'shamrockin.dst'现在是一个PNG文件，因此不能用read_dst读取它。（在错误消息UnicodeDecodeError: 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte中有一条线索：字节0x89总是first byte of a PNG file。）

恢复原始DST文件，并更改

pyembroidery.write_png(pattern, 'shamrockin.dst')

到
