FAQ

生成的图像是唯一的吗？

是的。本工具使用输入文本的哈希值作为种子来生成图案。相同的输入文本每次都会生成完全相同的图案，不同的输入产生截然不同的图案。这保证了唯一性和可复现性。

可以下载生成的图像吗？

可以。点击“下载PNG”按钮即可将当前生成的头像保存为PNG格式图片，分辨率200x200像素。你可以在任何平台上使用它作为个人资料头像。

头像图案是怎么生成的？

本工具使用类似Identicon的算法：将输入文本通过哈希函数生成一个数字种子，然后基于该种子在5x5网格中对称排列彩色方块，形成独特且视觉平衡的几何图案。左右对称的设计使得图案看起来更美观。

输入文本会被保存或上传吗？

不会。所有计算在浏览器本地完成，输入文本不会被上传到任何服务器。可以放心输入任何内容生成头像。
