Public methods

print(dpi, pageList) * experimental *

• dpi: the print rezolution of the document (try 100).
• pageList: the list (array) of pages to print.

Public static methods

createLoadingTask(src)

• src: see :src prop
  This function creates a PDFJS loading task that can be used and reused as :src property.
  The loading task is a promise that resolves with the PDFJS pdf document that exposes the numPages property (see example below).

beware: when the component is destroyed, the object returned by createLoadingTask() become invalid.

Examples

Example - current page / page count

<template>
    <div>
        {{currentPage}} / {{pageCount}}
        <pdf
            src="https://cdn.mozilla.net/pdfjs/tracemonkey.pdf"
            @num-pages="pageCount = $event"
            @page-loaded="currentPage = $event"
        ></pdf>
    </div>
</template>
 
<script>
 
import pdf from 'vue-pdf'
 
export default {
    components: {
        pdf
    },
    data() {
        return {
            currentPage: 0,
            pageCount: 0,
        }
    }
}
 
</script>

Example - display multiple pages of the same pdf document

<template>
    <div>
        <pdf
            v-for="i in numPages"
            :key="i"
            :src="src"
            :page="i"
            style="display: inline-block; width: 25%"
        ></pdf>
    </div>
</template>
 
<script>
 
import pdf from 'vue-pdf'
 
var loadingTask = pdf.createLoadingTask('https://cdn.mozilla.net/pdfjs/tracemonkey.pdf');
 
export default {
    components: {
        pdf
    },
    data() {
        return {
            src: loadingTask,
            numPages: undefined,
        }
    },
    mounted() {
 
        this.src.then(pdf => {
 
            this.numPages = pdf.numPages;
        });
    }
}
 
</script>

Example - print all pages

<template>
    <button @click="$refs.myPdfComponent.print()">print</button>
    <pdf ref="myPdfComponent" src="https://cdn.mozilla.net/pdfjs/tracemonkey.pdf"></pdf>
</template>

Example - print multiple pages

<template>
    <button @click="$refs.myPdfComponent.print(100, [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14])">print</button>
    <pdf ref="myPdfComponent" src="https://cdn.mozilla.net/pdfjs/tracemonkey.pdf"></pdf>
</template>

Example - get text content

<template>
    <div>
        <button
            @click="logContent"
        >
            log content
        </button>
        <pdf
            ref="myPdfComponent"
            src="https://cdn.mozilla.net/pdfjs/tracemonkey.pdf"
        ></pdf>
    </div>
</template>
 
<script>
 
import pdf from 'vue-pdf'
 
export default {
    components: {
        pdf
    },
    methods: {
        logContent() {
 
            this.$refs.myPdfComponent.pdf.forEachPage(function(page) {
 
                return page.getTextContent()
                .then(function(content) {
 
                    var text = content.items.map(item => item.str);
                    console.log(text);
                })
            });
        }
    }
}
 
</script>
