尽量将这个问题的信息量降到最低。如果太长，请见谅，感谢您阅读！
我试图让这些文本（它们有不同的字体和字体大小）适合头像图像的右侧，但遇到了困难。输出是一个 m3u8 播放列表文件，由前端 JS 视频播放器播放。请查看当前输出：https://postimg.cc/nXx34z96。此命令由 Node.js 控制器生成（这就是为什么您可以在其中找到多个 drawtext 过滤器，它们来自 for 循环）并且由于隐私原因我无法在此处复制粘贴它。
问题：有没有什么方法可以呈现所有文本副本，无论它们的字体系列和字体大小如何，对于所有三种文本：
- 文本不会被剪切或丢失
- 自动添加换行符
- 字体大小自动缩放
这样每行最多可以容纳 2 行文本？让我们根据字体系列假设每行最多 X 个字符（有些字体的字形比其他字体更宽）。
非常感谢任何反馈/指导！非常感谢！
所需的图形草图如下。
line1-with-font1
line2-with-font1(-if-needed)
[avatar] line1-with-font2
[ here ] line2-with-font2(-if-needed)
line1-with-font3
line2-with-font3(-if-needed)
我也尝试过将文本写入具有透明背景的图像（这样我就可以随后将其叠加到视频中）但我遇到了 png 图像上的文本太模糊的问题（使用了 imagemagickconvert并使用了不同的设置）。
