Bernina's .ART format is indeed proprietary, but Berinina owns a software company, OESD, that makes conversion software (e.g. the OESD Magic Box). You can create files using a documented file format, such as .PES, and use their software to convert the PES files into ART.

You could look at the open source <a href="http://embroidermodder.github.io" rel="noreferrer">Embroidermodder 2</a> and it's underlying library, libembroidery. At the time of writing, it doesn't support .ART, but .DST is a common format that most machines support which may work for you. Also, you could use libembroidery's .CSV format to lay out your stitches fairly easily so that all the format specifics are abstracted away and then convert the file with libembroidery-convert to an embroidery format that your machine supports. The .CSV format has the capability of specifying color changes, jump stitches and trimming.

blocks|key|1633549|text|根据this+thread的说法(诚然，已经有几年的历史了，所以他们最近可能已经开放了)，.art文件格式的细节由Bernina严密保护，不向开发人员提供，要求所有工作都通过他们的官方设计工具完成。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1633550|我认为您可以通过反复修改.art文件字节来逆向工程文件格式，但诀窍是将这些修改后的文件重新放回机器中。也许一个好的开始是修改一些字节，然后尝试让他们的设计软件重新打开文件。这种方法最大的问题是如果他们使用校验和。|1633551|entityMap|0|LINK|mutability|MUTABLE|url|http://sewing.patternreview.com/cgi-bin/sewingclasses/board.pl?t=9292^0|2|B|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

According to <a href="http://sewing.patternreview.com/cgi-bin/sewingclasses/board.pl?t=9292" rel="nofollow noreferrer">this thread</a> (admittedly a few years old, so maybe they've opened up recently) the details of the .art file format is closely guarded by Bernina and not made available to developers, requiring that all work is done through their official design tools. 

I would think you could reverse engineer the file format with some trial-and-error modification of the .art file bytes, but the trick is getting those modified files back into the machine. Perhaps a good start would be to modify some bytes and then try to get their design software to re-open the file. The big gotcha with this approach would be if they use a checksum.

It occurs to me that there's actually a very strong possibility that a Bernina embroidery machine accepts .DST files. While .ART is somewhat standard to make such files, a lot of embroidery machines accept .DST and those are <a href="https://edutechwiki.unige.ch/en/Embroidery_format_DST" rel="nofollow noreferrer">easy to code up and output</a>.
<hr />
.art files are in &quot;Compound File Binary Format&quot;. You split them up pretty easily. 7zip will do this. And anybody could write anything to traverse this. Inside the files however, there are usually:
<ul>
<li>[5]SummaryInformation</li>
<li>[5]WilcomDesignInformationDDD</li>
<li>AUX_INFO</li>
<li>Contents</li>
<li>DESIGN_ICON</li>
</ul>
So far though, so good.
Do note this is the same as the .emb format by Wilcom (tho .art calls this breakdown Grade C, because it doesn't contain the vector art file which is similarly compressed when it exists in emb)
In .emb the Contents file starts with a 4 byte little endian number indicating the size of the file in uncompressed format. Followed by a zlib compression stream. The resulting data clearly has an embroidery file with strings about the threads and a triplet code.
So that's certainly doable, but the OP is about .art. And here's where there's an slight snag. Where the 00 is it looks like there are D2 which generally would suggest a single byte swizzle.
<pre><code>F1 47 D2 D2 EE 9C 24 --- should be 
46 2B 00 00 78 9C ED --- (the icon file sizes are always the same)
</code></pre>
<hr />
The bit swizzle here is: XOR D2, cycle-shift-left 1.
So the contents element in the CFBF should be unswizzled XOR 0xD2, circular shifted left by 1. Then the first four bytes are size, and the rest are a zlib compression stream.
<hr />
<pre class="lang-py prettyprint-override"><code>import compoundfiles
import zlib


def swizzle(b):
 b ^= 0xD2
 b &lt;&lt;= 1
 b |= b &gt;&gt; 8
 return b &amp; 0xFF


def parse_art_file(file):
 with open(file, 'rb') as f:
 contents = compoundfiles.CompoundFileReader(f).open('Contents')
 contents.seek(4) # file size
 return zlib.decompress(bytes([swizzle(b) for b in contents.read()]))
</code></pre>
.emb files are the same but the swizzle for the contents doesn't exist.
Then you'd reverse engineer the file, etc.

My wife has a Bernina embroidery machine and I'd like to experiment with creating designs programmatically. I'd like to either find out how to output data in a format the machine's software will accept, or else find a free or inexpensive utility that can convert from a format I can produce (such as HPGL, or something else documented) to a format the machine can accept. My intention would be to output a file with one XY coordinate per stitch, plus instructions to change thread (pause for thread change); I don't need something to generate area fills, adjust stitch spacing, optimize stitching order, etc.; I'd expect to handle those things myself.

Anyone have any suggestions?

我的妻子有一台Bernina刺绣机，我想尝试通过编程来创造设计。我想找出如何以机器软件可以接受的格式输出数据，或者找到一个免费或便宜的实用程序，可以将我可以生成的格式(如HPGL或其他文档)转换为机器可以接受的格式。我的目的是输出一个文件，每针一个XY坐标，加上改变线的指令(暂停换线)；我不需要一些东西来生成区域填充，调整针距，优化缝合顺序等；我希望自己处理这些事情。有人有什么建议吗？
