Sorry, not sure what you are trying to do 😕

[Angeart]

ah, plz see following codepen. https://codepen.io/shinomiya_ag/pen/gdEGGa

Set Small Number to remove-button-size when canvas is so big. "Remove Button" position is in a strange position. I fix it.

@zhanziyang I was about to submit a similar PR, when you use say width=1920, the remove button is quite big, but luckily you have an undocumented "removeButtonSize" var to use, so you can set button size fixed to say width:30px! The thing is that when you use this "removeButtonSize" var (which is not documented thus maybe not fully supported), the button's style top and right properties are not updated!

Relevant code:

    <svg class="icon icon-remove"
       (...)
      :style="`top: -${height/40}px; right: -${width/40}px`"
       (...)
      :width="removeButtonSize || width/10"
      :height="removeButtonSize || width/10">

@Angeart does the tricky of correctly supporting that again, not documented, variable, TODO document it :P
