Share on FacebookTweet about this on TwitterShare on LinkedIn

We’re happy to announce that Aspose.PDF Cloud 19.10 has been just released and available on production server. We’re continuously evolving the Aspose.PDF Cloud based on your feedback and requests. We’ve added support of Radio Box and Check Box fields in this release. These new exciting features will help you to create more interactive fillable PDF forms for data collection with simple HTTP requests. Spare some time and check release notes of this version for a complete list of enhancements and improvements.

Let me give you a quick walk through of some of these features, carried in this new release. We’ll be using Aspose.PDF Cloud SDK for .NET to exhibit new feature. However, you can use the SDK of your preferred programming language available at GitHub in your application directly.

How to Add Checkbox Field in PDF?

While working with PDF forms, you need to create checkboxes for data collection when there are lists of options and the user may select any number of choices, including zero, one, or several. In other words, each checkbox is independent of all other checkboxes in the list, so checking one box doesn’t uncheck the others. In this release, Aspose.PDF Cloud introduced support of checkbox field. Now you can add, update and get checkbox from PDF document or specific page or by checkbox field name.

Follow these steps to add a pre-selected checkbox field in a PDF document:

Step 1: Signup with aspose.cloud to get App SID and App key

Step 2: Create a new project in Visual Studio

Step 3: Install Aspose.PDF Cloud SDK for .NET NuGet Package

Step 4: Create a new method with following code to add a checkbox field in a PDF document

A cURL example to update the presentation slide size:

How to Add Radio Button Field in PDF?

A radio button is a very common control used in the forms. These are used when there is a list of two or more options that are mutually exclusive and the user must select exactly one choice. In other words, clicking a non-selected radio button will deselect whatever other button was previously selected in the list. Now you can add, update, and get radio buttons from PDF document or specific page or by radio button field name.

Here we demonstrate how to add a radio button into a PDF document using C#:

Repeat 1-3 steps from above example if required and use following code snippet to add radio button option in PDF document.

How to Create and Read Barcodes with C# .NET REST API

Share on FacebookTweet about this on TwitterShare on LinkedIn

Barcodes are widely used around the world for the necessary data collection. A barcode is an encoded image used to represent data in a visual and machine-readable form. As a developer, you came across a number of scenarios, where you need to create and read barcodes in your application. In this article I will share a RESTful solution, Aspose.BarCode Cloud, for working with the barcode in your application. It eliminates the requirement to install and maintain a separate software to create and read barcodes.  

Aspose.BarCode Cloud is a platform independent barcode generation and recognition solution. It enables developers to create and read 1D (Linear), 2D and postal barcodes of 60+ symbologies that can be integrated universally into any workflow, html page, web application and desktop application. While creating new barcodes you can set barcode configurations, such as, barcode bar height, its dimensions, barcode image format and so on. The API generate and recognize barcode images in a variety of image formats: JPEG, PNG, GIF, BMP, TIFF, EMF, WMF, EXIF and ICON.

I’m using Aspose.BarCode Cloud SDK for .NET in this article. However, Aspose.BarCode Cloud also provides SDKs of all popular programming languages via GitHub and external Package Managers, so you can directly implement Aspose.BarCode Cloud in your favorite platform directly, with ease.

Here we go, we will follow these steps:

How to create the barcode

Step 1

First thing first, sign up with aspose.cloud to get your AppSID and AppKey

Step 2

Create a new project in Visual Studio and install Aspose.BarCode SDK for .NET package from NuGet

PM> Install-Package Aspose.BarCode-Cloud

Step 3

Copy paste the following code in the new project to create a barcode. I have used GetBarGenerate API method in this example, it creates the barcode with specified settings and returns the result in the response stream. I have created 2D barcode(datamatrix) in this example, you can create any barcode from the supported barcode types.

Step 4

Run the code, it will save the barcode image as PNG image format. You can use response stream as per your use case.

How to read the barcode

Repeat the above steps 1-2, if required.

Step 3

Copy paste the following code in the new project to read the barcode image from local drive. It recognizes the barcode image and return the barcode type and value.

Step 4

Run the code, the API reads all the barcode images from provided image and return the details in the response.

And that’s it. You see how easy is it to create a new barcode or read a barcode image with few lines of code.

What’s Next

In case you still haven’t met the API and haven’t worked with it, free trial is right here waiting for you to give it a try and explore the power of the Aspose.BarCode Cloud API. All you need is to sign up with the aspose.cloud and visit our developer resources for a quick start:

In this release, we have introduced LayoutTargetType property to control the layout mode of the chart plot area and support of Widescreen slide size along with many other important improvements. Please spare some time and check release notes of this version for a complete list of enhancements and improvements.

Let me give you a quick walk through some of these improvements, carried in this new release.

Setting Slide Size

The is a possibility that you have a mismatch between the size of your slides and the size of the medium you are projecting to because of your Microsoft PowerPoint version you have used to create your presentation and the device you are using to deliver the presentation. How you will fix it? Simply you should know the target device size before delivering your presentation to cope with the issue and update the presentation slide size.

Aspose.Slides Cloud has already provided an API PutSlidesSlideSize to update the size of presentations to industry standard presentation sizes. In this release, we have extended the list and added a new size; Widescreen. Following is the complete list of available sizes.

Available values for sizeType parameter:

 Parameter Value   Preset Size Type 
 OnScreen   On screen 4×3 
 LetterPaper   Letter 
 A4Paper   A4 
 Slide35mm   Slide 35mm 
 Overhead   Overhead 
 Banner   Banner

A cURL example to update the presentation slide size:

Layout Mode of Chart Plot Area

While adding charts in the presentations, setting layout mode for chart plot area is one of the frequently used features. In this release, we have introduced a new property LayoutTargetType to control the layout of the chart plot area. Now you can define the layout of the plot area manually by setting the new property, with two possible values Inner or Outer, This property specifies whether to layout the plot area by its inside (not including axis and axis labels) or outside (including axis and axis labels).

The following cURL example demonstrates how to Set Layout Mode of chart:

Convert scanned PDFs to searchable PDF using cURL

Share on FacebookTweet about this on TwitterShare on LinkedIn

PDF is the defacto file type to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Aspose.PDF Cloud provides a number of operations that work seamlessly with your existing PDF documents, allowing you to convert to and from PDF formats, extract document information and manipulate your PDF documents on cloud storage of your choice.

There are two main types of PDF documents – those that are created electronically using PDF creation software and those that are created from a scanner or other photo-imaging equipment. PDF creation software actually builds a PDF document that has an internal structure, denoting characters, fonts and position – although the raw information makes little sense to the human eye. A scanned PDF is basically just a flat image of a document – hence, scanning a page of text results in a picture of words being represented on the screen. In order to take information from this sort of scanned PDF, OCR technology is required so that each character can be optically recognized and then represented. 

Aspose.PDF Cloud provides a powerful inbuilt OCR engine that allows you to recognize and extract text tokens from PDF Documents. Using Aspose.PDF Cloud you can embed OCR layers in a PDF Document, allowing you to search and index your scanned PDF Documents.

Aspose.PDF Cloud OCR support

Aspose.PDF Cloud provides the below API for OCR support with PDF documents

Type Resource URL Description
PUT /pdf/{name}/ocr Generate OCR layer for images in the input PDF document

The above resource accepts the following arguments

Parameter NameDecription
nameThe PDF document to add OCR layer to
lang Language for OCR engine

The language parameter supports recognition of the following language codes eng (English), ara (Arabic) , bel (Belarusian), ben (Bengali), bul (Bulgarian), ces (Czech), dan (Danish), deu (German), ell (Greek), fin (Finnish), fra (French), heb (Hebrew), hin (Hindi), ind (Indonesian), isl (Icelandic), ita (Italian), jpn (Japanese) , kor (Korean), nld (Dutch), nor (Norwegian), pol (Polish), por (Portuguese), ron (Romanian), rus (Russian), spa (Spanish), swe (Swedish), tha (Thai), tur (Turkish), ukr (Ukrainian), vie (Vietnamese), chi_sim (Chinese Simple), chi_tra
(Chinese Traditional) or their combination e.g. eng,rus etc.

Using cURL to add an OCR Layer for embedded images

For testing purposes, we are using a simple PDF with a single image on the first page.

PDF containing text as an image

Read text from OCR Layer

Now that an OCR layer, we can read all text items from the PDF document. You can see the response contains tokens from our embedded image above. Please note this is a partial response.
