如何防止画布溢出卡并使其在vuetify中响应? [英] How to prevent canvas from overflowing the card and make it responsive in vuetify?

问题描述

上下文:

您好，我正在尝试在vuetify中使用fabricjs画布，并使其在所有屏幕中都具有响应性.但是目前，我面临一个问题，即画布无法基于卡片进行重新调整大小，而是使卡片溢出.我尝试使用v响应，但是它没有将纵横比应用于画布，可能是因为我使用的方式不正确.

Hi, I am trying to use fabricjs canvas within vuetify and make it look responsive in all the screens. But currently, I am facing an issue where the canvas is not re-sizing based on card,it overflows the card instead. I have tried using v-responsive but it does not apply the aspect ratio to canvas, could be, the way I am using it is not the right way.

任何建议都会有所帮助.

              class="green pb-0 justify-center"
            >
              <v-responsive aspect-ratio="4/3" class="mx-auto px-3">
                <canvas id="c"> </canvas>
              </v-responsive>
            </v-card-title>

推荐答案

可以通过样式表任意调整画布元素的大小，然后将其位图置于'object-fit'CSS属性之下.

A canvas element can be sized arbitrarily by a style sheet, its bitmap is then subject to the 'object-fit' CSS property.

来源

canvas元素的宽度/高度与canvas元素的位图的宽度/高度不同.这意味着您只能使用CSS样式来解决此问题.

The width/height of the canvas element are different from the width/height of the canvas element's bitmap. This means that you can use only CSS styles to fix this problem.

canvas {
  width: 100%;
  height: 100%;
  object-fit: cover;
}

示例

如果要保持宽高比，可以使用填充技巧.

If you want to maintain the aspect ratio you can use the padding trick.

.canvas-container {
  width: 100%;
  padding-top: 100%; // for 1:1 ratio
}
