How can add signature to pdf with laravel 5.5 laravel-snappy - laravel

I'm using Laravel 5.5 laravel-snappy to create PDF.
I just wanted to add a signature in my PDF.
I am not able to find nothing, is any pluging or something for that?
Thanks

In your pdf template, you could have an image of the signature (With transparant background i.e png) or signature text at the bottom and control its appearance as you like. for example opacity, size etc.
But if you want to digitally sign your pdf then you can use tcpdf

Generating pdf of web page in laravel

I want to generate a pdf of a form that a user fills and download it to the users computer.
I tried using the Dompdf package from laravel to do this and everything works fine except the design. The generated pdf does not look exactly like the web page, after doing some searching about this issue, I found out that dompdf does not support a few of the css option.
I was wondering whether there are any other free packages like dompdf that I could use which can have rich styling and convert the web page to pdf with the exact design.

How to open image file using pdftron

I want to load an image file using the pdftron webviewer api.
For pdf files it's working fine but I want to load image files and add annotations to them.
In the user guide there is no information regarding working with images.
Yes, WebViewer can do this out of the box.
There are a number of image formats supported. Here is the breakdown.
PNG, JPEG
Simply pass the image URL to WebViewer initialDoc constructor parameter, or to WebViewer.loadDocument().
If your URL does not have a proper file extension, then you can do the following.
myWebViewer.loadDocument("mydomain/generic_url_to_image", {filename: "input.png"})
This works with both PDFNetJS Lean and Full editions.
TIFF, GIF, BMP
You can utilize the browser's HTML5 canvas to load the images, and then generate PNG/JPG from the HTML5 canvas, and then pass the follow the instructions above.
JP2 or multiple images in one document.
Using PDFNetJS Full edition, which does not come with the standard WebViewer download, you have full control over PDF creation.
PDFNetJS Full Download: http://pdftron.com/downloads/PDFNetJS.zip
Using PDFNetJS Full you would follow the AddImage sample code to construct a PDF with the image(s) in it.

How do I embed full pdfs using ReStructured Text?

How do I embed a pdf using reStructured Text? With the following directive, I only get the first page.
.. image:: /pdfs/cv.pdf
For context, I'm trying to do this in a Pelican based blog.
A plugin for Pelican called pdf-img description says:
Searches for any tags within your article for which the source is a PostScript, EPS, or PDF file. It will produce a PNG preview of the file and this PNG will be displayed as the image. This preview will also act as a link to the original file. If the PDF/PS/EPS file is a multi-page document, then only the first page will be used for the preview.
That explains why you get those results.
I could find no plugin that "embeds a PDF" (by which I assume you want to embed a PDF viewer within your Pelican blog that would display the entire PDF, allowing the viewer to scroll through it in an iframe or something like that), but you can try searching for others.

Exporting Base64 image data / Canvas to PNG, JPG and PDF in GWT

Here is my first time that I want to raise my issue here. As the title now I have a trouble with exporting a base64 image data to PNG, JPG, and PDF in GWT so I need your help from you. Let I give you an overview what I want to do:
Please have a look here: http://testingqr.appspot.com/ This is my app to generate a qrcode. After process of customization the Qrcode, I want to export the QR code in the canvas to png,jpg and pdf. To do that I will add 3 buttons are "Export to PDF" "Export to PNG" "Export to JPG" after press on each of these button, a Download Dialog will appear (Save as dialog) to let user choosing the location they want to save to and the extension of the file too (Such as C:\test.png)
I already use dataToURL function to get a base64. I used CanvasTo Image library from this link http://www.nihilogic.dk/labs/canvas2image/ But it will download the image from canvas with no Save as dialog and no extension in FF or chrome (IE does not support for HTML5 Canvas). So that I cant export PNG and JPG. This is my first problem.
The second problem is exporting PDF in GWT, I want to work with an open source library. I tried PDF Box http://pdfbox.apache.org/userguide/cookbook.html But now it just supports the JPG type. I want something that convert to PDF from base64. Do you have idea to help me do exporting to PDF process. What I want is after I press on "Export to PDF" button, a dialog will appear to let me save the QRcode in PDF file to my local location.
So thank you all for any help. Have a nice day.

Is there any way to export a Google Visualization org chart as an image?

Is there anyway to have an export function to export the Google Visualization organizational chart as an image? I want this as a feature of my website, so people can click a button or a link and have it save as an image or a pdf file
Make a screen-shot of the browser. There are multiples tools out there to do this. We used this: http://code.google.com/p/speak-lib/source/browse/#svn/trunk/WebShot%3Fstate%3Dclosed
It works fine. We generate previews of design changes that way.
Try http://phantomjs.org/ you can write script to cut your web page into PNG images of some fixed size and then assemble them into PDF.
You can export the SVG code and send it to a server to convert it to an image. This is a scalable and easy solution. Answer details here: Convert Google Geochart to image (JPEG, PNG, etc.) or PDF in the browser
Use chart.getImageURI() it gives the image location
