Phantomjs zoomFactor - 将光栅化缩放到特定大小
Geo*_*uer 5 pdf svg rasterizing phantomjs
我正在光栅化以下简单的html + svg + foreignObject html

</html>使用这个简单的光栅化脚本:
webPage = require 'webpage'
args = (require 'system').args
url = args[1]
destination = args[2]
page = webPage.create()
page.paperSize = width: '10.5in', height: '7.5in', border: '0in'
#page.zoomFactor = 1.991
#page.viewportSize = (width: 1050, height: 75)
page.open url, (status) ->
if status isnt 'success'
console.log "Error!", url, status
return phantom.exit()
rasterize = ->
page.render destination
console.log "Rasterized", url, "to", destination
return phantom.exit()
setTimeout rasterize, 100
如您所见,单个可见元素的大小为1050px x 750px.我想将它精确地光栅化到尺寸为100%的10.5英寸x 7.5英寸纸张尺寸上.
我的光栅化脚本有:
page.paperSize = width: '10.5in', height: '7.5in', border: '0in'
结果是这样的pdf:
所以这不会扩展到全尺寸.我可以通过调整缩放系数来调整到全尺寸.实验上我发现这很有效
page.zoomFactor = 1.991
现在元素正确缩放但字体缩放太多.
如何保持原始字体大小,将纸张的左/最顶部1050px/750px缩小到纸上10.5inx7.5in？
您是否已经尝试过在 CSS 上使用媒体查询？
webPage = require 'webpage'
args = (require 'system').args
url = args[1]
destination = args[2]
page = webPage.create()
page.paperSize = width: '10.5in', height: '7.5in', border: '0in'#
page.zoomFactor = 1.991# page.viewportSize = (width: 1050, height: 75)
page.open url, (status) - >
if status isnt 'success'
console.log "Error!", url, status
return phantom.exit()
rasterize = - >
page.render destination
console.log "Rasterized", url, "to", destination
return phantom.exit()
setTimeout rasterize, 100@media print {
body {
margin: 0;
background-image: none;
height: 10.5in;
width: 7.5in;
}
}
p {
border: 1px solid red;
font-size: 8pt !important;
}

outline: 1px solid purple;
