The developer is not Chinese, so I suggest you use English to ask questions. By the way, I am also a Chinese, and my English is very poor. I usually use Baidu Translation to solve this problem. This library was last updated on December 5, 2020, so I suggest you solve this problem with other libraries.

Maybe imagescript or imagemagick can help you. Please refer to: https://deno.land/x/imagescript @v1.2.14/mod.ts https://deno.land/x/imagemagick_deno @0.0.14/mod.ts

This is a sample, I use other libraries to solute another problem: https://github.com/denorg/qrcode/issues/9

=========================================================================== 开发者并非中国人，因此建议您使用英文进行提问。顺便说说，我也是一名中国人，而且我的英语挺差的，通常我使用百度翻译来解決这个问题。 这个库上次更新于2020年12月5日，所以建议您结合其它库来解决这个问题。

也许deno库imagescript或imagemagick能帮助到您，请参考： https://deno.land/x/imagescript@v1.2.14/mod.ts https://deno.land/x/imagemagick_deno@0.0.14/mod.ts

OK, I'll answer in English, if you don't mind. For the time being, no, that's the format returned, with the intention that it's included directly in an HTML img tag. As @edu-sonya-cc says (thanks!), converting it to an actual image can be achieved by using another library, or using these lines:

const data = base64string.slice(22);
const bytes = Uint8Array.from(atob(data), (c) => c.charCodeAt(0));
await Deno.writeFile("tests/test.gif", bytes);

We might include that as an upgrade to this library, it wouldn't be too hard.
