问题描述

有什么办法解决这个问题? 我试图将宽度和高度设置为毫米.如何将其设置为全角?

Is there any way to solve this? I tried to set width and height in mm. How can I set it to full-width?

推荐答案

您可以像下面那样获取PDF文档的宽度和高度，

You can get the width and height of PDF document like below,

var doc = new jsPDF("p", "mm", "a4");

var width = doc.internal.pageSize.getWidth();
var height = doc.internal.pageSize.getHeight();

然后，您可以为图像使用此宽度和高度以适合整个PDF文档.

Then you can use this width and height for your image to fit the entire PDF document.

var imgData = 'data:image/jpeg;base64,/9j/4AAQSkZJ......';

doc.addImage(imgData, 'JPEG', 0, 0, width, height);

确保图像具有与PDF文档相同的尺寸(分辨率).否则，它将看起来变形(拉伸).

Make sure that your image has the same size (resolution) of the PDF document. Otherwise it will look distorted (stretched).
