I have implemented Azure Cognitive Read service to return extracted/OCR text from a PDF.
However, to make it easier for the user to understand the context/copy and paste data from the PDF i would like to overlay that text data over the PDF. I would then drop that PDF into a viewer.
Does anyone have any ideas on how to proceed. Would also be happy to use AWS. Basically an API that i submit a PDF to and it returns an OCR'd PDF is what i am after. If this is not possible, a library that i can submit the text and the PDF (and return a text searchable PDF) is also ideal.
I am looking for something similar and stumbled upon this:
https://learn.microsoft.com/en-us/azure/cognitive-services/form-recognizer/overview?tabs=v2-1
This is the Azure form recogniser.
What is Azure Form Recognizer?
Azure Form Recognizer is a part of Azure Applied AI Services that lets you build automated data processing software using machine learning technology. Identify and extract text, key/value pairs, selection marks, tables, and structure from your documents—the service outputs structured data that includes the relationships in the original file, bounding boxes, confidence and more. You quickly get accurate results that are tailored to your specific content without heavy manual intervention or extensive data science expertise. Use Form Recognizer to automate data entry in your applications and enrich your documents search capabilities.
They have an online example test:
https://fott-2-1.azurewebsites.net/prebuilts-analyze
Create a service in azure for free and test if it fits your needs. From there you will get a json reply and you can use the boundingBox to display. I haven't gone as far as applying the bounding box or something like that to the pdf.
You also have a free development nuget package to do exactly as you want:

OCR development is free for testing and see if it works for you.

I am trying to integrate our third party application with NetSuite. I want to be able to import sales invoice details generated from our third party system (which uses REST API) into the NetSuite invoice form.
The frequency of import is not too crucial- an immediate import will be ideal, but sending data once a day is fine as well.
I want to know what I have to use to do this API integration - SuiteTalk, RESTlet or Suitelet.
I am completely new to this topic and after a few days of research, I learned that there are 3 options for an API integration with netsuite (Suitelets, restlets and suitetalk which comprises REST and SOAP based web services). I also learned that there are scheduled scripts and user events, but I'm not too clear on the idea.
I need some help identifying which integration option I should choose.
Any and all information about netsuite API integration is appreciated!
I would avoid REST/SOAP. SOAP is outdated, and REST is incomplete and difficult to use.
Suitelet's are for when you want to present your own custom UI to frontend users, like a special new kind of custom form not relevant to any particular record. Probably not what you want.
What you probably want is to design a restlet. A restlet is a way for you to setup your own custom url inside NetSuite that your program can talk to from outside NetSuite. Like a webpage. You can pass in data to the restlet either inside the URL, or inside the body of an HTTP request (e.g. like a JSON object), and you can get data back out from the body of the HTTP response.
A restlet is a part of SuiteTalk. The method of authenticating a restlet is the same for the method of authenticating a request to the REST API. So, learning about SuiteTalk is helpful. The code you use to write the restlet, SuiteScript, is the same kind of code used to write suitelets and other kinds of scripts.
So you will want to learn about SuiteTalk, and then, in particular, SuiteTalk restlets.
this is a really subjective issue.
It used to be that SOAP/SuiteTalk was a little easier in terms of infrastructure and since Netsuite's offerings are ever changing the REST/SuiteTalk might fill this space in the future.
Since Netsuite deprecated the Full Access role setting up integrations almost always involves the integrator having to provide a permissions spec. The easiest way to do that is via a Bundle. For token based authentication (TBA) there also needs to be an integration record from which you need Consumer Id and Secret Tokens.
So as of this writing the set up for SOAP/SuiteTalk and RESTLets is roughly the same. The easiest way to communicate these is with a bundle so if you are a Netsuite dev with a dev account you can set these up in a bundle and have your customer import them.
So equal so far but differences:
SOAP/Suitetalk is slow. IMO not suiteable for an interactive interface
SOAP/Suitetalk the code is all in your external app so changes to the code don't require any changes in the target account.
RESTlets can be pretty speedy. I've used these for client interactions.
Updates require re-loading your bundle or overwriting your bundle files in the target account (with the resulting havoc if an admin refreshes the bundle)
RESTlets give you access to the features of the account on which you are running so that code can run appropriate chunks For instance features such as matrix items, multi-location inventory, one-world, pick/pack/ship, volume pricing, multi-currency will all change the data model of the account your code is running against. RESTlets can detect which features are enabled; SOAP/SuiteTalk cannot.
So really the only advantage at this point that I see for SOAP/Suitetalk is that code updates don't require access to the target account.
Who is making the changes? If it is your NetSuite developers, then your options are SUITELET or RESTLET.
If its your third-party application team, they own the code and the process and do all their work sitting outside of NetSuite - your option is SUITETALK/SOAP. Of course, they need to know something about NetSuite, but your business analyst would be sufficient to support them. As of 2020.1+, there is also support for native REST APIs in addition to SOAP in case you still want to use REST, but not write your own RESTLETS.
As the above comments mention, Suitetalk does perform a little slower than calling RESTLETS. So that maybe one of the deciding factors.
You may consider SUITELETs for integration only if you want to bypass all authentication schemes, by setting the suitelet as public. Highly inadvisable though.
If the third-party application supports REST APIs, you could call them directly from within NetSuite - either from user events or from scheduled scripts.
You can also consider iPAAS platforms like Dell Boomi, Celigo, Jitterbit, etc. These are general-purpose integration platforms, and make connecting one platform to another easy, with minimal coding. If your Company is already invested in these iPAAS platforms for other enterprise applications, then the choice is that much simpler.
I would like to make my own CNC Editor.
I am looking for some guidance. I don’t know if it is even possible with HTML5. But it would be great if I can. If possible, please list what I should research and learn.
I don’t need it to be online accessible, I will only have it on my computer. I will be accessing it via local network from multiple different computers. I don’t want it accessing the internet, because it’s not always available.
Desired Features:
⁃ Read and Write files with different extensions (all files used are easily opened in notepad)
⁃ Store and retrieve data from a simple database file.
⁃ Make calculations
⁃ Have a text Editor window
⁃ Have a Display area for simple vector graphics depending on data loaded and provided by user.
It is possible but requires a lot of work. I would say that these are technologies you would need to master in order to pull this off:
Node.js (use express.js) - for storing and retrieving files from database and for reading/writing local files with extensions you want (server-side)
Vue.js or Angular.js or React - for building frontend interface to manipulate your vector graphics. It can also do calculations and It's good with svgs and that kind of stuff.
Electron.js (not mandatory) - it wraps it in native-app like experience. This framework actually gives you ability to write desktop apps for any os and arch.
So as I said, It would be a lot of work but its possible in the end.
Funny coincidence is that my brother is planning to build CNC machine so I might be doing this as well in next couple of months. Feel free to contact me if you need any further help!
UPDATE: You cant do it with just HTML5. It would be like trying to make wooden space shuttle.
I have a couple of questions about offline storage in HTML5. It's not an area I am that familiar with so I was hoping someone could shed some light.
I want to develop a web based system (for mobile) that a user could potentially use offline. Obviously the first time they'd use it (and any time they need to sync data thereafter), internet access would need to be required.
Some text data would need to be downloaded in json format. Basically this will be a list of certain items that will appear in auto-complete forms in the app (ie. even if the user is offline and they want to enter a type of animal for example, they'd type in "Gir" and "Giraffe", being one of the items downloaded in that json list, would appear in the auto-complete box.
I would like the user to be able to take photos at certain points. This would need to be saved internally, such that when internet access is available it can be synced/uploaded to some web server.
Could someone tell me if what I am thinking of is achievable?
Thanks
Use a cache manifest to keep offline portions of your app cached. You can also store key/value data in Local Storage, including text and blobs (which you should be able to convert to photos).
This demo (and its documentation) may be a useful resource for offline photo storage.
So this is more of a general question about apps and techniques rather than a specific code question...
When developing an larger app, how would a developer access lots of data from a website. The example I'll use is an app like Yelp. They have both a web-access site and an app, both share the same information. I would imagine that information like that is stored on the website via some sort of MySQL database and the iOS device access's it as needed based on the user's requests.
How might a developer writing an app start something like this? I assume you need to somehow securely tie the MySQL database to iOS and so on. I've seen a lot of techniques on the web, but they all seem very simple and not safe for a large scale app.
Any ideas would be awesome!
The key term you're looking for is "API" (Application Programming Interface).
A Yelp iOS app won't access Yelp's databases directly. There will be a layer (I simplify here somewhat) between that and the iOS app; this layer will provide a series of methods (the API) by which clients can make queries and potentially manipulate remote state.
A common API format is JSON over HTTP, and indeed, this is what the official Yelp API seems to be.
Good starting points would be the documentation for NSURLConnection and NSJSONSerialization, and the Yelp API documentation I link above.
Suppose I want to write a program to read movie info from IMDb, or music info from last.fm, or weather info from weather.com etc., just reading the webpage and parsing it is quiet tedious. Often websites have an xml feed (such as last.fm) set up exactly for this.
Is there a particular link/standard that websites follow for this feed? Such as robot.txt, is there a similar standard for information feeds, or does each website have its own standard?
This is the kind of problem RSS or Atom feeds were designed for, so look for a link for an RSS feed if there is one. They're both designed to be simple to parse too. That's normally on sites that have regularly updated content though, like news or blogs. If you're lucky, they'll provide many different RSS feeds for different aspects of the site (the way Stackoverflow does for questions, for instance)
Otherwise, the site may have an API you can use to get the data (like Facebook, Twitter, Google services etc). Failing that, you'll have to resort to screen-scraping and the possible copyright and legal implications that are involved with that.
Websites provide different ways to access this data. Like web services , Feeds, Endpoints to query their data.
And there are programs used to collect data from pages without using standard techniques. These programs are called Bots. These programs use different techniques to get data from websites (NOTE: Be careful Data may be copyright protected)
The most common such standards are RSS and the related Atom. Both are formats for XML syndication of web content. Most software libraries include components for parsing these formats, as they are widespread.
yes rss standard. And xml standard.
Sounds to me like you're referring to RSS or Atom feeds. These are specified for a given page in the source; for instance, open the source html for this very page and go to line 22.
Both Atom and RSS are standards. They are both XML based, and there are many parsers for each.
You mentioned screen scraping as the "tedious" option; it is also normally against the terms of service for the website. Doing this may get you blocked. Feed reading is by definition allowed.
There are a number of standards websites use for this, depending on what they are doing, and what they want to do.
RSS is a protocol for sending out formatted chunks of data in machine-parsable form. It stands for "Real Simple Syndication" and is usually used for news feeds, blogs, and other things where there is new content on a periodic or sporadic basis. There are dozens of RSS readers which allow one to subscribe to multiple RSS sources and periodically check them for new data. It is intended to be lightweight.
AJAX is a protocol for sending commands from websites to the web server and getting results back in a machine-parsable form. It is designed to work with JavaScript on the web client. The AJAX standard specifies how to format and send a request and how to format and send a reply, as well as how to parse the requests and replies. It tends to be up to the developers to know what commands are available via AJAX.
SOAP is another protocol like AJAX, but it's uses tend to be more program-to-program, rather than from web client to server. SOAP allows for auto-discovery of what commands are available by use of a machine-readable file in WSTL format, which essentially specifies in XML the method signatures and types used by a particular SOAP interface.
Not all sites use RSS, AJAX, or SOAP. Last.fm, one of the examples you listed, does not seem to support RSS and uses it's own web-based API for getting information from the site. In those cases, you have to find out what their API is (Last.fm appears to be well documented, however).
Choosing the method of obtaining data depends on the application. If its a public/commercial application screen scraping won't be an option. (E.g. if you want to use IMDB information commercially then you will need to make contract paying them 15000$ or more according to their website's usage policy)
I think your problem isn't not knowing the standard procedure for obtaining website information but rather not knowing that your inability to obtain data is due to websites not wanting to provide that data.
If a website wants you to be able to use their information, then there will almost certainly be a well documented api interface with various standard protocols for queries.
A list of APIs can be found here.
Dataformats listed at this particular sites are: CSV, GeoRSS, HTML, JSON, KML, OPML, OpenSearch, PHP, RDF, RSS, Text, XML, XSPF, YAML, CSV, GEORSS.
