(More specific Giorgio Bozio)
I have been using Rotativa for the last year to print simple html to pdf and its been working fantastic. Very happy with product, but now recently i have been trying to do something a little more advance and i keep having the same issue.
Normally i would send Rotativa a simple invoice view (Predefined HTML) with model data populated via Razor and this worked well, but now i am trying to implement template's for my invoices. Customers can create their own template layouts with a custom 3rd party form designer and then upload its template file into my site. I take this file and parse it and generate the elements of the invoice with stringbuilder and div tags. I then send the generated HTML to the view that uses a #HTML.Raw() to populate the invoice html. Rotativa then takes this View and generates a pdf, but when it generates the pdf its quality of the text is horrible and blurry. Thus it generates the template correctly, but does some sort of shrinking or something to make the text not look crisp.
I have tried everything, from playing with custom switches to playing with the dimensions of the html.
When i copy the generated html to a view and just generate the pdf plainly then it prints fine, but as soon as i push the html to the view with HTML.Raw i seem to land up with fussy text.
Giorgio Bozio, does Rotativa have a issue with Html.Raw? or can you perhaps open a dialog with me to try and resolve this issue? Really hope you can help me...or someone can help me. Desperate and dont really want to change Rotativa for something else.
Please help.

I have used CKEditor for a few years without really understanding it. I now want to use it to display text which will include HTML, CSS, JavaScript and PHP example code. None of that needs to execute it is just to show the code to others.
Currently I used the textarea replace method to edit content and I need to carry on that way. When I add the content first time it is sanitised (mysqli_real_escape_string) and stored in a MySQL database correctly. It also then displays correctly with the CKEditor markup working as markup and the HTML/PHP showing as a code example. However, when I edit the content a second time the HTML examples become "real" HTML and are no longer visible as examples.
For example this:
<?php echo "hello"; ?>
<p>Hello</p>
is correctly (?) stored as:
<p><?php echo "me"; ?></p>
<p><p>Hello</p></p>
and displays on the page as shown in the first code snippet (which is what I want). When I then hit edit again the code examples vanish into the background as real HTML (part of the page). If I put the code examples in as code snippets (which I would rather not have to do because of the intended users) the result in the editor (second edit) looks like this:
<!--?php echo "me"; ?-->
Hello
I am sure i am missing a basic understanding of what is going on behind the scenes but can anyone explain how to allow users to type in text which includes HTML, CSS, JavaScript, PHP and MySQL code examples which must then appear as examples and not markup (and be editable as examples).
I have played with config.entities and config.protectedSource after some research but they do not seem to be relevant (or to work). Weirdly a couple of times it seemed to work fine and I thought I had cracked it but then stopped with no further changes to the config. That means I now have less idea what I am doing than when I started!
You don't mention which version you are using, but if it's relatively new (4.4+) you can use the Code Snippets plugin that was designed exactly for this. See the demo at http://ckeditor.com/demo#widgets. It might help with the encoding issues too. There's docs on it too.
Th help with the current encoding issue, it would help a LOT if you showed us how you output the data and load it into CKEditor. For example "When I then hit edit again" doesn't really describe anything without context. For example, do you use setData() with AJAX? Do you use an inline editor? Code examples would be the best.
i need to display an image on a page which i developed from content/pages. But i dont know how i can display image and pass dynamic data to this page.
Well! after waiting for people to answer i did some research and found that this work is done through tags and involves the use of partials.
Not sure if what I want to do is possible, but what I am hoping to do is somehow gather certain pieces of text from a website, remove the header, footer, background, all formatting, and place it into my application in a scrollview or something similar...
I'll give you an example... Imagine I was making wikipedia's iPhone app, I want to download the information about the wiki on dogs, without the header, side bars etc, just the text. How would I go about doing this?
I understand that for this I have not provided any example code or what I've tried or started, but that's just because in this case I'm lost! That doesn't mean I want full chunks of code either. Any help will do. If this doesn't work, I will just have to make a 'mobile optimised' version of the webpages I want to include in my app.
Thanks
(Edit: the term I was trying to use was 'strip the web page of its HTML coding')
You may be going about this the wrong way, or perhaps even asking the wrong question.
Does the target website have an API or datafeed of some kind?
Can you get the information you need in JSON or XML format directly from the site?
I think you've misunderstood the technology. HTML is merely the framwork on which the formatting and data is hung.
Parsing the HTML page seems like an awfully big headache, I doubt you'll ever be able to get it to work, because almost all sites these days are partially or wholly generated on the server side, the page is only the result.
Some sites hide the information in memory and others get it dynamically through ajax for example, which means that simply trying to get the data by parsing the HTML will get zero data.
Another issue you should be aware of though, is that simply copying the data from generated websites may open yourself up to copyright issues.
You have to parse the html code and search for the part that you want and "throw" away the part that you do not need. This is more or less like bruteforcing and the code of the website should not change otherwise you are screwed. So you have to write the parser by hand with this method. But maybe there is a atom or rss feed and you can parse this one. This will be much more easier and you are not depending on the website layout because the rss/atom feed is just about the data. For parsing rss you could try out NSXMLParser.
And then you have to make a valid html page out of the data and present it in the UIWebView
I'm trying to find tutorials or code to allow users to customise their page, just like twitter ,wordpress and tumblr do.
Could someone tell me what technology their using?
i'm a .net developer, but maybe they're using jquery?
Any help would be great.
Thanks
You can use javascript to change style sheets and the DOM
Question is a bit broad. To change the page you simply need to manipulate the DOM or change the CSS associated with the page's elements. This can be done any number of ways. E.g. you could write out a new CSS class dynamically, you could add new elements to the DOM itself or you could modify the existing attributes of the page. e.g. to set the background of the page you can do something like:
(assuming JQuery)
$("body").css('background-image','url(path/to/image)');
Hope that helps,

I'm looking for a way to generate pdf files from html
In order to make simple tabular reports I would need the following features
table rendering
variable page size
repeating headers / footers on every page
calculated page number / total page
css support would be nice
I know there have been many similar questions in stackoverflow, but I don't know if there's a product that supports the aforementioned features...
Ideally, the source would be a plain and simple well built html with css, (I'm building the html files, so I can adapt to the products needs, that is, it won't have to render every piece of html crap you can throw at a browser) and with some custom tags to configure headings, footer, page size, etc...
then I would run a command line to convert it from html to pdf.
I think http://www.allcolor.org/YaHPConverter/ does something like that
Take a look at TCPDF
Check out the examples.
