"Simple shell utility to convert html to pdf using the webkit rendering engine, and qt." http://code.google.com/p/wkhtmltopdf/ GNU Lesser GPL
mac
brew install wkhtmltopdf
linux
apt-get install wkhtmltopdf
see: http://code.google.com/p/wkhtmltopdf/wiki/compilation compiled versions available at: http://code.google.com/p/wkhtmltopdf/downloads/list
finally make sure the following command works as expected:
wkhtmltopdf www.google.de test.pdf
put the following line into your Config.groovy and adjust the path to your wkhtmltox binary ( which wkhtmltopdf )
unix
grails.plugin.wkhtmltox.binary = "/usr/bin/wkhtmltopdf"
windows
grails.plugin.wkhtmltox.binary = "C:/local/wkhtmltopdf/wkhtmltopdf.exe"
also add the pdf mime type to Config.groovy
grails.mime.types = [
all: '*/*',
.....
pdf: 'application/x-pdf'
]
to stream the content of an controller-action as pdf just call: /context/some/someAction.pdf
class SomerController {
def someAction = {
def someInstance = SomeDomainObject.get(params.id)
render( filename:"File ${someInstance.id}.pdf",
view:"/some/someGspTemplate",
model:[someInstance:someInstance],
header:"/pdf/someHeader",
footer:"/pdf/someFooter",
marginLeft:20,
marginTop:35,
marginBottom:20,
marginRight:20,
headerSpacing:10,
)
}
}
Or create binary pdf data and use them for any other purpose
class SomeService implements Serializable {
def byte[] pdfData = wkhtmltoxService.makePdf(
view: "/pdf/someGspTemplate",
model: [someInstance: someInstance],
header: "/pdf/someHeader",
footer: "/pdf/someFooter",
marginLeft: 20,
marginTop: 35,
marginBottom: 20,
marginRight: 20,
headerSpacing: 10,
)
// DO Something e.g. send as mail
//sendAsynchronousMail {
// multipart true
// to "[email protected]"
// subject "see PDF Attachment";
// attachBytes "PDF Attachment.pdf", "application/x-pdf", pdfData
// body "see my pdf attachment"
//}
}
}
write your gsps as usual, just make sure, that the url's to the resources are absolute and reachable by the host maschine
<link rel="stylesheet" href="${resource(dir: '/css/style.css', absolute: true)}" type="text/css"/>
<img src="${resource(dir: '/images/image.jpg', absolute: true)}" width="200px"/>
