How to import
<script setup lang="ts">
import { Image, ImagePreview } from '@fibrous/semi-ui-vue';
</script>
Basic usage
You can get an image with preview function by specifying the image path through src, and specify the width and height of the image through width, height

Code
<script setup lang="ts">
import { Image } from '@fibrous/semi-ui-vue';
</script>
<template>
<Image alt="Abstract colorful artwork" :height="200" src="/assets/root-web-sites/abstract.jpg" :width="360" />
</template>Loading failed placeholder
fallback takes the URL of the image shown when loading fails (a string). For custom content use the #fallback slot, which takes precedence when both are given

自定义加载失败占位图

Code
<script setup lang="ts">
import { IconUploadError } from '@fibrous/semi-icons-vue';
import { Image } from '@fibrous/semi-ui-vue';
</script>
<template>
<div :style="{ display: 'flex', alignItems: 'center', flexDirection: 'column' }">
<span>加载失败默认样式</span>
<Image alt="加载失败的图片" :height="200" src="https://load-error.jpeg" :width="200" />
<br />
<span>自定义加载失败占位图</span>
<Image alt="加载失败的图片" :height="200" src="https://load-error.jpeg" :width="200">
<template #fallback>
<IconUploadError :style="{ fontSize: '50px' }" />
</template>
</Image>
</div>
</template>Progressive loading
Large images can be progressively loaded through the #placeholder slot

Code
<script setup lang="ts">
import { ref } from 'vue';
import { Button, Image } from '@fibrous/semi-ui-vue';
const timestamp = ref('');
</script>
<template>
<Image alt="Abstract colorful artwork" :height="200" :src="`/assets/root-web-sites/abstract-big.png?${timestamp}`" :width="300">
<template #placeholder>
<Image alt="" :height="200" :preview="false" src="/assets/root-web-sites/abstract-small.jpeg" :width="300" />
</template>
</Image>
<br />
<Button :style="{ marginTop: '10px' }" theme="solid" @click="timestamp = String(Date.now())">Reload</Button>
</template>Customize the preview image
You can customize the preview image by setting the src of the Image component to be different from the src in the preview parameter

Code
<script setup lang="ts">
import { Image } from '@fibrous/semi-ui-vue';
const preview = {
src: '/assets/root-web-sites/abstract-big.png',
};
</script>
<template>
<Image alt="Abstract colorful artwork" :height="200" :preview="preview" src="/assets/root-web-sites/abstract-small.jpeg" :width="300" />
</template>Multi-image preview
Use ImagePreview to wrap Image to achieve multi-image preview




Code
<script setup lang="ts">
import { Image, ImagePreview } from '@fibrous/semi-ui-vue';
const srcList = ['/assets/root-web-sites/abstract.jpg', '/assets/root-web-sites/sky.jpg', '/assets/root-web-sites/greenleaf.jpg', '/assets/root-web-sites/colorful.jpg'];
</script>
<template>
<ImagePreview>
<Image v-for="(src, index) in srcList" :key="src" :alt="`lamp${index + 1}`" :src="src" :style="{ marginRight: '5px' }" :width="200" />
</ImagePreview>
</template>Use the preview component alone
The preview component ImagePreview can be used alone, through v-model:visible (or visible with @visibleChange) to control whether to preview, src to pass in the image that can be previewed, and previewTitle (a string) to set the title at the top of the preview
Code
<script setup lang="ts">
import { ref } from 'vue';
import { Button, ImagePreview } from '@fibrous/semi-ui-vue';
const srcList = ['/assets/root-web-sites/abstract.jpg', '/assets/root-web-sites/sky.jpg', '/assets/root-web-sites/greenleaf.jpg', '/assets/root-web-sites/colorful.jpg'];
const visible1 = ref(false);
const visible2 = ref(false);
</script>
<template>
<Button @click="visible1 = true">Preview single Image</Button>
<ImagePreview v-model:visible="visible1" src="/assets/root-web-sites/sky.jpg" />
<br />
<Button :style="{ marginTop: '20px' }" @click="visible2 = true">Preview multiple Images</Button>
<ImagePreview v-model:visible="visible2" previewTitle="Scenery" :src="srcList" />
</template>Render in the specified container
You can specify the parent DOM of the preview component through getPopupContainer (you need to specify position: relative), and the image preview will be rendered into this DOM. This will change the DOM tree position, but not the view's rendering position.
When the container is not document.body (including a getPopupContainer set only on ConfigProvider), the preview is non-modal: it does not output aria-modal, does not trap Tab and does not lock page scrolling. Returning document.body from getPopupContainer is the same as not passing it.



Code
<script setup lang="ts">
import { useTemplateRef } from 'vue';
import { Image, ImagePreview } from '@fibrous/semi-ui-vue';
const srcList = ['/assets/root-web-sites/abstract.jpg', '/assets/root-web-sites/sky.jpg', '/assets/root-web-sites/greenleaf.jpg'];
const container = useTemplateRef<HTMLDivElement>('container');
// called when the preview opens, after the container is mounted
const getPopupContainer = () => container.value as HTMLElement;
</script>
<template>
<div ref="container" :style="{ height: '400px', position: 'relative' }">
<ImagePreview :getPopupContainer="getPopupContainer" :style="{ height: '100%', display: 'flex', alignItems: 'center', justifyContent: 'center' }">
<Image v-for="(src, index) in srcList" :key="src" :alt="`lamp${index + 1}`" :src="src" :style="{ marginRight: '5px' }" :width="200" />
</ImagePreview>
</div>
</template>Customize the bottom operation area of the preview
The bottom action area of the preview can be customized with the #previewMenu slot, which receives MenuProps. Images wrapped by ImagePreview use the slot of ImagePreview; a standalone Image uses its own slot of the same name
If you want to customize the bottom operation area based on the default one, use the menuItems slot parameter: an array of the default items as VNodes, in the order previous, page counter, next, zoom out, zoom slider, zoom in, original size / fit to page, rotate and download. Render them with <component :is>
Customize the preview top display area
The #title="{ title, index }" slot replaces the content of the title section at the top of the preview. When there is a title, the preview dialog is named by that section through aria-labelledby, so its name is the text the slot renders; without a title the name is "Preview" from the locale. Use #closeIcon to replace the close icon, and #leftIcon="{ index }" and #rightIcon="{ index }" to replace the arrow icons


Code
<script setup lang="ts">
import { Image, ImagePreview } from '@fibrous/semi-ui-vue';
const srcList = ['/assets/root-web-sites/abstract.jpg', '/assets/root-web-sites/sky.jpg'];
</script>

A number for width or height is in px. class and style land on the root element; other undeclared native attributes and listeners land on the inner img. The preview object accepts the props and callbacks of ImagePreview (onVisibleChange, onChange, onClose, onZoomIn, onZoomOut, onPrev, onNext, onRatioChange, onRotateLeft, onDownload, onDownloadError), except lazyLoad, lazyLoadMargin, class and style (use previewCls and previewStyle to style the preview). Custom nodes do not go in preview; use the slots of Image. When preview.src is an array, switching images returns to "fit to page". An Image inside an ImagePreview ignores #title, #previewMenu, #leftIcon, #rightIcon and #closeIcon; the slots of the ImagePreview apply.

class, style and native attributes land on the root element (the group div) through attrs; with aria-label or aria-labelledby and no role, the root gets role="group". The preview dialog is rendered into getPopupContainer (document.body by default) and is named by previewTitle, or by the locale when there is no title.
MenuProps
min, max, step and zoom are percentages (a min of 10 means 10%, a step of 10 means 10% per step), unlike minZoom, maxZoom, zoomStep and initialZoom of ImagePreview, which are factors (such as 0.1 and 5).

Accessibility
ARIA
- When rendered into
document.body(the default), the preview is a modal dialog withrole="dialog"andaria-modal="true"; rendered into a custom container (getPopupContainerreturns another element, including a container set on ConfigProvider) it is a non-modal dialog and does not outputaria-modal. It is named by its title (previewTitle, orpreview.previewTitleof an image in a group) when there is one, otherwise by "Preview" from the locale - Close, the left and right arrows, and the footer's previous, next, zoom out, zoom in, original size / adapt to the page, rotate and download controls are native
buttonelements. Their accessible names come from the matchingprevTip,nextTipand other tip props, or from the locale when those are not set. The zoom slider is named "Zoom" from the locale, with the current percentage as itsaria-valuetext - At the first or last image, or at a zoom limit, the matching footer button gets
aria-disabled="true"and stays focusable, so focus is not lost. The download button is also disabled when there is no current image (an emptysrclist) - The footer page counter has
aria-live="polite", so screen readers announce the new position when the image changes - With the preview enabled and the image loaded, the root of an Image thumbnail is a focusable button (
role="button",tabindex="0",aria-haspopup="dialog") named by thealtof the image; withpreviewset to false, or before the image has loaded, it is not focusable. Closing the preview returns focus to the thumbnail. A thumbnail inside an ImagePreview group that opens with the mouse also opens with the keyboard: while loading or after a load error it still has the button role and is focusable, and Enter or Space opens the group preview - The
altof the preview image is thealtof the thumbnail it shows (anImagePreviewsrcarray has no alt, so it is an empty string)
Keyboard interaction
- With focus on a thumbnail, Enter or Space opens the preview
- Opening the preview moves focus into it. In a modal preview, Tab and Shift + Tab cycle through its controls and closing it returns focus to the element focused before; a non-modal preview rendered into a custom container does not trap Tab, and on close focus returns to the element focused before only if it is still inside the preview or on body, and stays where it is when it has moved elsewhere on the page
- Enter or Space presses the focused button
- ← and → switch to the previous and next image, swapped in RTL (ConfigProvider
direction="rtl"). At the first or last image they behave like the buttons: they wrap around wheninfiniteis true and do nothing otherwise - ← and → do not switch images while focus is in an input, textarea, select or editable element (such as an input in a custom footer), or while Alt, Ctrl, Meta or Shift is held; on the focused zoom slider they change the zoom
- Esc closes the preview (unless
closeOnEscis false) - After the controls hide because of
viewerVisibleDelay, a key press or focus on a control shows them again; they stay shown while focus is on one of them
