Please reply...
You could use a Web Viewer to render the HTML then take a screenshot of selected coordinates using ScriptMaster's "Screen Capture" module.

What if a JSON file has HTML in it.
How do we run HTML in flutter apps?
like if there is h4 tag, that should be a little bigger than regular text and so so.
Is there a way to do that?
get the html value from the json and render it on the app using this package:

I am experimenting with tinyMCE and a have a few questions. Using their image handler which inserts an image into the textarea. I use echo $_POST['textarea'] to verify it displays properly on a web page, and it does.
Looking at the HTML code in the browser webconsole, I see the image referenced as: <img title="IMG_1908.JPG" src="data:iamge/jpeg;base64,/9j/4s/...>
A few questions:
Is this image reference actually a base64 image and not just a reference link? How can I see this?
Where does this image "file" actually reside?
If I just saved the data represented by $_POST['textarea'] into a database field, would it capture the entire contents in the database so I can just retrieve it and echo it? Should it be a BLOB field?
Thanks in advance!
Answers:
The firefox web console is a little misleading as it truncates the actual Base64 data, making it look like a short reference link, when in fact, it is typically super long showing all the base64 data characters.
Looking at the web browser's page source actually shows the base64 image in it.
Yes, the tinyMCE HTML form textbox named as 'textarea' can be saved using the $_POST['textarea'] global variable, into a mySQL BLOB field, then can retrieve the same field and echo it to display it again. The echo shows the exact same format that was seen in tinyMCE during input.
I know coldfusion has extensive pdf support, but I'm not sure if this is possible.
I was given a pdf form and told to make it so it is both filled out online, the data is captured, and the form can be printed.
Obviously, I can create an html page that looks like the document, save everything, generate the filled pdf form, etc.
Alternately, I think I can show the pdf, have them fill it, then grab the form data. I'm not entirely sure I can do this though, because I would need to detect when they are done filling it out.
But I was thinking it would be nice if I could do it this way - Show the pdf embedded on the webpage, let them fill it out and print it, then capture everything when they are done. I was looking through the CF documentation (cfpdf cfhttp, etc), but not finding exactly what I need. Is this an option?
You can extract the data from a PDF using the cfpdfform tag or as an HTTP Post. Here's a link to the docs on how to do that, but it depends on how you set up the PDF itself. You can edit your PDF form to actually submit just the formdata to a given CF page. It arrives on the page in a struct tied to the form name (ie. #form.form1.Fields.blah# etc.). Dump it out to deipher it (it's kind of convoluted) So you could fire print and submit from within the PDF.
The second way is to submit the PDF itself as a file. In this case you use the cfpdform tag - not well documented or widely used. Both approaches are covered lightly in the link above. Good luck!
We can show the pdf on page using cfheader and cfdocument tags. We can only show the pdf on webpage using the following example code.
<cfsavecontent name="pdfcontent">
//Here what you need to show the pdf
</cfsavecontent>
<cfheader name="Content-Disposition" value="filename=Mydocument.pdf">
<cfdocument format="pdf" orientation = "landscape" bookmark="Yes" marginleft=".25" marginright=".25" marginTop = ".25" marginbottom=".75" scale="90">
<cfoutput> #pdfcontent# </cfoutput>
</cfdocument>
I want to create a tutorial inside a form showing how to use my database. I created it in PowerPoint and saved it as a PDF. I was wondering if it was possible to attach this PDF in my form. I also saved these slides as images on my computer, tried to attached them to a form and it exceeded 22 inches in lenght. is there any way around this any suggestions perhaps?
You could use javascript and other tools to show the pdf as a slideshow, I recommend that you use this tool its free and you can integrate your slides in a very easy way with javascript.

I have loaded a PDF into UIWebView. Now i want to search for strings in that pdf. So I used a string which contains JS steps(used to highlight that specific string) and evaluated it with the webView object like this. But no result was obtained .It was as if nothing had been done.
Dont the JS evaluation work on a pdf loaded into a webView? Is there anyother way to search for a string in a PDF loaded into webView?
Even if you could evaluate JS against a webview that is currently displaying a pdf, the pdf render has no exposed or documented APIs. If you have code that works on HTML then it is not working because the PDF is not exposing an HTML like dom. If you have code that works in the acrobat plugin on a desktop then it won't work because the phone uses a derivative of Apple's Webkit PDF plugin which does not export the same API as Acrobat (as far as I know it exports no API, and if it does it is undocumented). In any event, regardless of why you think your code should work, it won't.
If you want to find a string in a pdf you are going to need to write code to parse the PDF and find that string, and even then you will not be able to highlight the specific string in the webview based renderer.
If you want this sort of functionality you should should use Quartz to directly render your PDFs onto views. Apple provides documentation for how to do that.
