I have a webform with and want to open it on smartphone - than take pictures of some documents which need to be merged in one PDF, and on the end this file need to be uploaded to server.
My solution is to use Google Drive to upload PDF (scan) to GDrive and then somehow download this file from gdrive to server via some sort of widget (any links appreciate) installed on website.
Maybe someone have a better idea?
I know its late but my answer might help others. I also face the same challenge and implemented a custom solution based on Javascript and Since you are using web form so this solution will perfectly fits on your need.
You have to use JSPdf javascript library, JSPdf provide you pdf object in your browser and you can upload it download it and there are many other thing to play with.
First you have to initialize JSPdf object as per your requirement. I am creating PDF with page size width:500px and height 500px.
pdf = new jsPDF("l", "pt", [500,500]);
Simply when you will take picture from camera you will have each picture in form of base64, that base64 format you have to insert in JSPdf object
pdf.addImage(imgData, 'JPEG', 0, 0);
you can repeat the above code to add pictures from camera as much as you want, at the back-end these images are compiling and creating pdf document where each page have each images in sequence.
Once you are done, you can get PDF object in form of base64 object using below code that you can upload to any server.
pdf.output('datauristring')
above is only pdf part, you can find complete working example including camera part here Javascript Component to Scan Document

I'm developing a UWP app for tablet and i need to generate a PDF with data from SQLite. I need to do this completely offline because where I will use the app there is no connection. What could I do?
I'd prefer not to use paid libraries like Syncfusion and XFinium so I'm trying to find an alternative solution.
I tried with iTextSharp but unfortunately I can't find a good documentation to render a complex PDF or to export a Bitmap generated from a Grid Component to a PDF File.
Why not render your data into a webpage displayed with a WebView control? Then you can use any permissive licensed javascript library to generate the PDF.
If it hasn't changed much, then you can only send text back and forth between your WebView and UWP app, but that's workable. Your final PDF result can be read back as a base64 encoded string.
A very quick search found this one that seems easy to use and you can just download the source to put into your app:

I need to display uploaded scans (JPG, PNG, TIFF, PDF, etc.) in the browser's window instead downloading them to a local pc and using external apps like Acrobat Reader.
I made some research in the web on that issue but wasn't really successful.
Does anyone have hints, code snippets, how to achieve that ?
EDIT :
Since I am not looking for a solution which supports viewing scans in a typical browser like Chrome, FireFox, etc. but supports viewing scans in an XPage view within Notes I need to ask my question again.
What is the best (recommended) way to view different types of scans, uploaded as PDF, JPG, TIFF, PNG, etc., in Notes within an XPage view ?
Take a look here, XPages: Embed PDF and possibly Office files
Here is some code that I have in an app for PDF's.
I tried using Bumpbox, and pdf.js and while I could get them working, iframes seemed to work best for me with using normal Domino attachment urls in xpages
I am not sure if this solution is right or not, but it works well for an app I have that only has PDFs. It does work on mobile too, at least on iOS.
<iframe
src="#{javascript:
var url = 'https://app.nsf/';
var doc = sessionScope.docID;
var atname = #RightBack(sessionScope.aname,'Body');
var end = '/$file'+atname;
return url+doc+end}"
width="800" height="1000">
</iframe>
If you are looking at using different file types you need to use a renderer, give it the attachment URL, and then display what the renderer returns with. I haven't looked at this in a while so things might have changed. Look for a lightbox clone that can display pdf. I think Orangebox was one, bumpbox looks to not be updated but I was able to get that working for me.
This method will display everything inline. I would love to see some type of renderer like pdf.js for xpages.
We have been using Google Drive SDK for our app.
Since 2 October, when our app tries to create a Google Docs native document by uploading a html file contains img tags, the result become partly corrupted. Although the upload request finishes without error, all the images in the html are lost in the created document.
The behavior is not usual. For nearly two years, basically, the conversion for document insertion had interpreted the img tags and created embedded images. It seems like a server side problem exists.
Is it a known issue and would be fixed?
Or, is there something I'm missing and it is correct behavior?
[About the htmls we use]
The htmls for upload are based on exported "text/html" files from existing Google Docs documents.
All the img tags have src attribute with absolute url. They start with https and all of them are links on googleusercontent.com.
Apart from the img tags, all the html tags seems to be handled as before.
[How to reproduce the problem]
This problem can be reproduced by using DriveSample app in "Google APIs Client Library for Objective-C". Modify "DriveSampleWindowController.m" to force document conversion turned on (i.e., query.convert=YES;) just before uploading a file to Drive.
Download an existing Docs document with images as html.
Upload it as a new document to Google Drive (with document conversion turned on).
Open the uploaded document in 2 with Google Docs web editor. All images would be lost in the document. Also, no spinning wheels will be shown for the lost image areas.
The problem seems fixed on the server side within the last half day. Thank you for fixing it, Google.
I'm evaluating Fine Uploader compared to various other options, specifically JQuery File Upload.
I generally prefer the Fine Uploader approach as it's more lightweight, compared to JQuery File Uploader which has dependencies on Bootstrap and JQuery UI.
However it's important to be able to resize images: e.g., a user may select a large file from their camera and this may be very large - uploading the full resolution photo may take a very long time. JQuery File Upload doe this.
Additionally we don't have much use for very high resolution files.
If possible (I'm aware some browsers may not support this), I'd like to be able to resize images client size.
Is this possible?
Fine Uploader does not currently have any native support for image manipulation. This is a feature in our backlog, but we have not had many users tell us they are interested in this. This is one of the reasons why such a feature has yet to be implemented natively. There is a case, #707 that marks the start of native image-editing support for Fine Uploader. It is tentatively scheduled for 4.0.
However, you can certainly make use of FileReader and Canvas to resize the image. You can then submit this resized image as a Blob to Fine Uploader via the addFiles API method. At that point, the file has been submitted and Fine Uploader is ready to upload the item.
Essentially, the steps you would follow to handle this specific scenario, before Fine Uploader natively supports image manipulation:
Provide your own file input element(s) or make use of Fine Uploader's file/folder drag and drop support to get a handle on some files selected by the user.
Use FileReader to read the contents of the image.
FileReader will provide you with a URL for the image, assign that to the src attribute of an img element.
Draw the img onto a canvas element. This is where the resizing occurs.
Grab the URL of the resized image from the canvas element (canvas.toDataURL(...)).
Convert the URL to a Blob.
Pass the Blob to the addFiles API method of Fine Uploader.
The intent is to take care of most if not all of this for integrators such as yourself in the future by adding native image manipulation support to Fine Uploader.
Hope this helps.
How to display PDF thumbnails in ASP page
There is no built in functionality for ASP to process and manipulate PDF files. You will need to install a custom component on your server, make sure your webhost allows this, or ask them for a list of installed objects as they often have ones that will do what you want.
A good free on is GFlax:
http://download.cnet.com/GFLAx/3000-10248_4-10327603.html
It will allow you to chop a PDF up into seperate JPEG files, and from there you can get the object to resize the JPEGs into different thumbnail sizes for your needs.
The GFlax documentation should get you started.
Have you looked at this? Mapsoft ThumbNails
you can use Ghost script sharp for displaying pdf thumbnail . Here is the code
GhostscriptWrapper.GeneratePageThumb(filepath, thumbnailPath, 1, 20, 20);
