I've encountered a weird issue with Phantomjs when converting an html file to pdf. My html, resulting pdf, and rasterize.js files are below:
http://401web.com/_pub/2TRTI8E.html
http://401web.com/_pub/2TRTI8E.pdf
http://401web.com/_pub/rasterize.js
You will notice that in the PDF file, at page 6, the content gets cut off and then on page 7, the content is repeated and is then correct all the way to the end of the document.
The html file contains a series of tags with their src attributes set as data:image/png;base64...
The application call to the phantom library is as follows:
phantomJS.Run("C:\path\to\directory\rasterize.js"),
new[] { webpath, outFilePdf, "A4", "1", "portrait"}, null, null);
Note that sometimes the rendered pdf file will exhibit the break/repeat behavior in different locations within the document eg: page 7 instead of 6) but the same issue always occurs.
Also, I am using phantomjs throughout my application (with the same rasterize.js script) with no other issues. This only happens on this export and only if there are a number of images.
My theory is that there is something going on with the image.onload event, specifically with base64 data but I have no idea how to troubleshoot this.
This is all within a .Net MVC application. I am using the PhantomJS nuget package found here: https://www.nuget.org/packages/PhantomJS/
Help is greatly appreciated.
Update: when running phantomjs locally via command line I was receiving the error below:
[CRITICAL] QNetworkReplyImpl: backend error: caching was enabled after some bytes had been written
libpng error: Read Error
I solved this (though I have no idea how/why) by replacing the cdn references in the html file to font-awesome.css and weather-icons.css files with locally hosted versions. After that, no more error and no more duplicate content.

I would like the browser to download file on button click of blade page. The following is used in controller and and added in provider file, but its showing in browser console but not downloading file.
use PDF;
// this controller
function sensorChartPDF(){
$pdf = PDF::loadView('sensorchartpdf');
return $pdf->download('invoice.pdf')->header('Content-Type','application/pdf');;
}
///// sensorchartpdf.blade.php this is view ///

chart static code appened in this file
To signify to the web browser that the file should be downloaded and not displayed in line you have to specify the content-disposition header with a value of attachment.
Your question, however, does not appear to be purely a question regarding Dompdf. With Dompdf you would merely use the following:
$dompdf->stream("output.pdf", array('Attachment' => 1));
I'm providing this for anyone looking for similar issue when working with the library directly.
Since you're not using Dompdf directly but via another library so you'll need to specify exactly which library or framework you're using before somebody can provide an accurate answer.
I am having an issue with PDF's in the latest Typo3 release. If I add PDF to the Image content element, I get this:
The file info looks like this:
Checking the Image Processing Test of Typo3, no errors are returned. PDF/AI also seems to be fine.
I tested several PDF's and AI files as well, they won't show dimensions either.
I have the suspicion that the command 'identify' does not work within Typo3, it still returns perfect results from shell.
Any idea where to look?
multiple reasons possible:
you just need to reimport metadata (scheduler task)
your PDF is coded in an unsual format (there is more then one option in PDF to include the title image)
missing/wrong rights:
maybe another program is executed from commandline than from PHP.
maybe the file can't be accessed correctly from ghostscript started from web
I am executing my automation scenarios using SpecFlow with Visual Studio.
I want to Embed a custom image to the HTML report which was generated by SpecFlow. That image is a screenshot i am taking whenever scenario is failed in Hooks.
Please help me out.
This is what i am seeing in the html report - enter image description here
Take a look at the SeleniumWebTest sample project here. This sample project shows how to include a screenshot in your report. While the example is Selenium-based, the same principles apply to other frameworks.
A more in-depth explanation of how this works can be found here under "Including Screenshots". Essentially, you need to abuse the console and use it to output your images' file paths.
Any data written to the console is available in your report (this is how the trace details are received by the report). You will need to parse the data written to the console and strip out the file path you want to embed. Make sure that you strip the image path completely so that you don't output the file path as part of the other trace information received from the console.
Edit: I've since discovered that there seems to be an issue with the template in the sample project. The following section in the template is bugged:
class="log">#Raw(FormatTechMessages(traceEvent.TechMessages.TrimEnd()).Replace("SCREENSHOT[ <a href="http://specflow.org/plus/documentation/,-/" data-page=",-"<img width='1000' src=").Replace("</a> ]SCREENSHOT", "</img>"))</pre>
This is because the console no longer seems to be formatting the file as a hyperlink, so the replacement string is never found. Updating this line in ReportTemplate.cshtml seems to have done the trick:
<pre class="log">#Raw(FormatTechMessages(traceEvent.TechMessages.TrimEnd()).Replace("SCREENSHOT[ ", "<img width='1000' src=\"").Replace(" ]SCREENSHOT", "\"</img>"))</pre>
As the console is no longer formatting the file as a hyperlink, you only need to replace the padding (in this case the "SCREENSHOT[]SCREENSHOT") from the string and instead enclose the path with the <IMG> tag. You also need to add the quotes around the file path.
I'm trying to get the example for creating a PDF/A document with Apache PDFBox up an running (CreatePDFA.java).
For this I copied the example class as is into a project module that includes a maven-dependency on PDFBox in version 2.0.0-RC3. I only changed the method signature and used a fixed font, filename and message instead of args[].
When trying to run the code I get an NPE in Line 107 because it cant't load the color profile (InputStream is null) When I check the included library in the project details I can see the resources folder, but it does not contain the expected file, namely "pdfa/sRGB Color Space Profile.icm".
Unfortunately, google-ing the problem only turned up more references to always the same example implementation, but after a while I acutally found what seems to be the needed file on apache.googlesource.com
I copied the file to our own resource directory and then used this line of code instead:
InputStream colorProfile = CreatePdfA.class.getResourceAsStream("/pdfa/sRGB Color Space Profile.icm");
This finally stopped the NPE - the file is apparently found - but now I get another exception which says:
java.lang.IllegalArgumentException: Invalid ICC Profile Data
Here, I'm stuck. I had hoped that this would work just out of the box, but it seems like I am missing something. Any ideas?
You already answered one part of the problem yourself: put the file into your resource directory.
The second problem may be a bad repository mirror or a transfer problem (binary to ascii). Here's the official repository URL with the ICC profile from the example:
https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/resources/org/apache/pdfbox/resources/pdfa/
I have an html template which I need to render as a .PDF and then save that pdf file on server. I'm using "rendering" plugin of grails. I'm able to render file as PDF but I don't understand how to save it on server location and not on user's system. Can anybody please help me ?
The pdfRenderingService provided by the plugin allows you to call render and get back an OutputStream. Using that output stream you can write that to a file on your server. The documentation explains the basics of using the service.
Your code may look something like this:
new File("report.pdf").withOutputStream { outputStream ->
outputStream << pdfRenderingService.render(template: '/report/report', model: [serial: 12345])
}
Well, actually I changed my plugin. Got Wkhtmltopdf plugin of grails more helpful. you can find it here --
https://github.com/quorak/grails-wkhtmltopdf
Also instructions regarding using this plugin you can find on the same link or here --
[https://github.com/quorak/grails-wkhtmltopdf]
Using this you can get "bytes" which you can write to file system.
