Add Image In Header Using Html-pdf Node Module


Answer :

It is possible to add the image in options header. 1.Load the image in html body with "display:none" style. 2.Then add the image in the options header By doing this the image is cached and can attach the image in header.

    var options = {     "format": 'Letter',     "orientation": "portrait",     "header": {     "contents": "<img src='image path' />",         "height": "30mm"   },   "footer": {     "contents": footer   } } pdf.create("<div style='display:none'><img src='image path' /></div>", options).toFile("sample.pdf", function(err, res) {         if (err) {                 console.error(err);                 callback();         }  });

Refering to this issue on the github, you can't put your image directly in options.header, you have to put it in the body inside a <div id="pageHeader"></div>:

var pdf = require('html-pdf'); var path = require('path');  // this is very important, you have to put file:// before your path // and normalize the resulting path var imgSrc = 'file://' + __dirname + '/350x120.png'; imgSrc = path.normalize(imgSrc); // or var imgSrc = path.join('file://', __dirname, '/350x120.png');  // Options var options = {     "header": {       "height": "45mm",       "contents": ""     },     "footer": {       "height": "28mm",       "contents": "<span style='color: #444;'>{{page}}</span>/<span>{{pages}}</span>"     }   } // put your entire header here and the content of the page outside the <div id="pageHeader"></div> var result = "<div id='pageHeader'><img src='" + imgSrc + "' /><div style='text-align: center;'>Author: Marc Bachmann</div></div>"; result += "<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>"; var fileName = __dirname + '/test.pdf'; pdf.create(result, options).toFile(fileName, function(err, res) {   if (err) {     console.error(err);   } });

With this code, I get this pdf:

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
