文转图
Tip
为了方便开发,您可以使用 AstrBot Text2Image Playground 在线可视化编辑和测试 HTML 模板。
基本
AstrBot 支持将文字渲染成图片。
@filter.command("image") # 注册一个 /image 指令,接收 text 参数。
async def on_aiocqhttp(self, event: AstrMessageEvent, text: str):
url = await self.text_to_image(text) # text_to_image() 是 Star 类的一个方法。
# path = await self.text_to_image(text, return_url = False) # 如果你想保存图片到本地
yield event.image_result(url)
自定义(基于 HTML)
如果你觉得上面渲染出来的图片不够美观,你可以使用自定义的 HTML 模板来渲染图片。
AstrBot 支持使用 HTML + Jinja2 的方式来渲染文转图模板。
# 自定义的 Jinja2 模板,支持 CSS
TMPL = '''
<div style="font-size: 32px;">
<h1 style="color: black">Todo List</h1>
<ul>
{% for item in items %}
<li>{{ item }}</li>
{% endfor %}
</div>
'''
@filter.command("todo")
async def custom_t2i_tmpl(self, event: AstrMessageEvent):
options = {} # 可选择传入渲染选项。
url = await self.html_render(TMPL, {"items": ["吃饭", "睡觉", "玩原神"]}, options=options) # 第二个参数是 Jinja2 的渲染数据
yield event.image_result(url)
返回的结果:
这只是一个简单的例子。得益于 HTML 和 DOM 渲染器的强大性,你可以进行更复杂和更美观的的设计。除此之外,Jinja2 支持循环、条件等语法以适应列表、字典等数据结构。你可以从网上了解更多关于 Jinja2 的知识。
图片渲染选项(options):
请参考 Playwright 的 screenshot API。
timeout(float, optional): 截图超时时间.type(Literal["jpeg", "png"], optional): 截图图片类型.quality(int, optional): 截图质量,仅适用于 JPEG 格式图片.omit_background(bool, optional): 是否允许隐藏默认的白色背景,这样就可以截透明图了,仅适用于 PNG 格式full_page(bool, optional): 是否截整个页面而不是仅设置的视口大小,默认为 True.clip(dict, optional): 截图后裁切的区域。参考 Playwright screenshot API。animations: (Literal["allow", "disabled"], optional): 是否允许播放 CSS 动画.caret: (Literal["hide", "initial"], optional): 当设置为 hide 时,截图时将隐藏文本插入符号,默认为 hide.scale: (Literal["css", "device"], optional): 页面缩放设置. 当设置为 css 时,则将设备分辨率与 CSS 中的像素一一对应,在高分屏上会使得截图变小. 当设置为 device 时,则根据设备的屏幕缩放设置或当前 Playwright 的 Page/Context 中的 device_scale_factor 参数来缩放.
