pdfkit 生成小比例的 pdf

Question

我正在使用 pdfkit 以从 html 字符串生成 pdf，由我的 Django 视图呈现。

由于某种原因，输出的 pdf 很小。我的 pdfkit 选项字典是 -

options = {
            'quiet': '',
            'page-size': 'A4',
            'margin-top': '0.75in',
            'margin-right': '0.75in',
            'margin-bottom': '0.75in',
            'margin-left': '0.75in',
            'disable-smart-shrinking': ''
        }

输出文件是here

Html代码为-

Answer 1

问题是关于设置 pdfkit 的 dpi 参数。

所以如果您遇到同样的问题，请根据您的需要设置dpi。对我来说，这就是我所需要的

options = {
            'page-size': 'A4',
            'dpi': 400
        }

Answer 2

我遇到了同样的问题。我刚刚更改了默认配置：

PDFKit.configure do |config|
    config.default_options = {
        page_size: 'A4',
        print_media_type: true,
        dpi: 400
    }
end

Answer 3

您可以尝试通过以下选项禁用收缩

options = { 'disable-smart-shrinking': ''}
