Merge Multiple Presentation by Passing List of All Files in .NET Apps

Dec 31 2012 04:26 AM | Aspose in Source Code

This technical tip allows developers to merge multiple presentation files using Saaspose.Slides REST API in your .NET applications. You can pass a list of all the files you want to merge using this example. Developers need to upload all the input files (Presentation1.pptx, Presentation2.pptx and Presentation3.pptx in case of this example) before running this example. Please check Upload File to Saaspose for how to. Some important steps for performing this task are to specify product URI, build URI, build URI to download merged presentation and Save output file.

Sample Code for Merge multiple presentations

SaasposeApp.AppKey = "89**********************";
SaasposeApp.AppSID = "77***********************";
//specify product URI
Product.BaseProductUri = @"[url="http://api.saaspose.com/v1.0%22;"]http://api.saaspose.com/v1.0";[/url]
string[] presentationsList = new string[] { "Presentation2.pptx", "Presentation3.pptx" };
PresentationsList list = new PresentationsList();
list.PresentationPaths = presentationsList;
string strJSON = JsonConvert.SerializeObject(list);
//build URI
string strURI = "[url="http://api.saaspose....n1.pptx/merge%22;"]http://api.saaspose....n1.pptx/merge";[/url] //Product.BaseProductUri + "/pdf/" + basePdf + "/appendDocument?appendFile=" + newPdf + "&startPage=1&endPage=" + iPageCount.ToString();
string signedURI = Utils.Sign(strURI);
Utils.ProcessCommand(signedURI, "POST", strJSON);
// build URI to download merged presentation
strURI = "[url="http://api.saaspose....ntation1.pptx%22;"]http://api.saaspose....ntation1.pptx";[/url]
signedURI = Utils.Sign(strURI);
using (Stream responseStream = Utils.ProcessCommand(signedURI, "GET"))
{
	//Save output file
	using (Stream fileStream = System.IO.File.OpenWrite("C:\\MergedPresentation.pptx"))
	{
		Utils.CopyStream(responseStream, fileStream);
	}
}
//Following is the PresentationsList class
/// <summary>
/// represents list of presentations to be merged
/// </summary>
class PresentationsList
{
	public PresentationsList() { }
	public string[] PresentationPaths { get; set; }
}
//build URI to upload file to Saaspose
			string strURI = "[url="http://api.saaspose....emoteFileName%22;"]http://api.saaspose....emoteFileName";[/url]
			string signedURI = Sign(strURI);
			UploadFileBinary(localfilepath, signedURI, "PUT");

Dec 27 2012 04:47 AM | Aspose in Source Code

This technical tip allows developers to extract image text from remote image URL using Saaspose.OCR REST API in their Java applications. Some important steps for performing this task is to build URI to extract text, sign URI, execute signed URI request and get response, Parse and deserialize the JSON to an object and Display the value and type of all the extracted text.

Sample Code for for Extracting Image Text from Remote Image URL

//build URI to extract text
	 String strURI = "";
			strURI = "[url="http://api.saaspose.com/v1.0/ocr/recognize?url=http://s017.radikal.ru/i406/1202/7b/70183bef7a09.jpg&language=english&useDefaultDictionaries=true%22;"]http://api.saaspose....ionaries=true";[/url]
	 //sign URI
	 String signedURI = Sign(strURI);
	 //execute signed URI request and get response
	 InputStream responseStream = ProcessCommand(signedURI, "POST");
	 String strJSON = StreamToString(responseStream);
	 // Parse and deserialize the JSON to a object.
	 OCRResponse ocrResponse = gson.fromJson(strJSON, OCRResponse.class);
			// Display the value and type of all the recognized barcodes
			for (Part part : ocrResponse.getPartsInfo().getList())
			{
				System.out.println("Text: " + part.getText());
				System.out.println("Font Name: " + part.getFontName());
				System.out.println("Font Size: " + part.getFontSize());
				System.out.println("Bold: " + part.getBold());
				System.out.println("Italic: " + part.getItalic());

How to build an advanced ASP.NET AJAX Photo Editor

Feb 13 2011 05:13 PM | AWS in Code Samples

This ImageDraw demo demonstrates how easily you can use ImageDraw object model and ASP.NET AJAX Framework to design an advanced AJAX-based Photo Editor.

The following figure is a screenshot of the ASP.NET AJAX Photo Editor application that leverages ASP.NET AJAX Framework, ASP.NET AJAX Control Toolkit and ImageDraw.

<img style="vertical-align: middle;" src="http://www.neodynami...0/figure01.jpg" alt="" />

This AJAX Photo Editor features:
- UI leveraging ASP.NET AJAX Control Toolkit
The left pane of AJAX Photo Editor UI leverages on ASP.NET AJAX Control Toolkit components like Accordion and Slider. The Accordion control is used to divide some Imaging Effects in categories. Those Imaging effects leverage ImageDraw object model and Slider controls are used for setting up some parameters that each effects feature.

For example, the following figure shows how Slider controls are used so the user can specify which Brightness, Contrast, Gamma, Saturation and Hue levels must be apply on the target photo.

<img src="http://www.neodynami...0/figure02.jpg" alt="" />

- Imaging Effects provided by ImageDraw
AJAX Photo Editor provides some of the most common imaging effects that well know photo editor software features like Basic Tuning (Brightness, Contrast, Gamma, Saturation, and Hue), Coloring (Convert to Black & White/Grayscale, Sepia and Negative/Invert), Rotation and Flipping and Scaling. In addition to those basic imaging effects, we introduced two new interested effects called Perspective View and Reflection which are built-in ImageDraw object model.

For example, the following figures show Coloring settings like Black & White/Grayscale and Negative/Invert:

<img style="vertical-align: middle;" src="http://www.neodynami...0/figure03.jpg" alt="" />

The following figure shows Rotation and Flipping feature:

<img style="vertical-align: middle;" src="http://www.neodynami...0/figure04.jpg" alt="" />

And the last one figure shows Composite Imaging Effects (Reflection + Perspective View + Scaling):

<img style="vertical-align: middle;" src="http://www.neodynami...0/figure01.jpg" alt="" />

Feb 13 2011 05:11 PM | AWS in Code Samples

We often get queries from customers who would like to convert their text files to PDF. We are often asked if we can quickly provide some code which can accomplish this task and save them the effort of going through the documentation. So for the benefit of everyone, we present here a simple example which can be used as it is to easily and efficiently convert a text file to PDF using <a href="http://www.aspose.co...>.
[C#]

<code>
System.IO.TextReader tr = new StreamReader("test.txt");
//Instantiate Pdf pbject by calling its empty constructor
Aspose.Pdf.Pdf pdf1 = new Aspose.Pdf.Pdf();
//Create a new section in the Pdf object 
Aspose.Pdf.Section sec1 = pdf1.Sections.Add();
//Create a new text paragraph and pass the text to its constructor as argument
Aspose.Pdf.Text t2 = new Aspose.Pdf.Text(tr.ReadToEnd());
sec1.Paragraphs.Add(t2);
pdf1.Save("test.Pdf");
[VB.NET]
Dim tr As System.IO.TextReader = New StreamReader("test.txt")
\\'Instantiate Pdf pbject by calling its empty constructor
Dim pdf1 As Aspose.Pdf.Pdf = New Aspose.Pdf.Pdf()
\\'Create a new section in the Pdf objects
Dim sec1 As Aspose.Pdf.Section = pdf1.Sections.Add()
\\'Create a new text paragraph and pass the text to its constructor as argument
Dim t2 As Aspose.Pdf.Text = New Aspose.Pdf.Text(tr.ReadToEnd())
sec1.Paragraphs.Add(t2)
pdf1.Save(\\"test.Pdf\\")
</code>
[Java]
<code>
try{ try
StringBuffer sb = new StringBuffer(1024);
BufferedReader reader = new BufferedReader(new FileReader("test.txt"));
char[] chars = new char[1024];
int numRead = 0;
while( (numRead = reader.read(chars)) > -1){
sb.append(String.valueOf(chars));
}
reader.close();
//Instantiate Pdf pbject by calling its empty constructor
Pdf pdf1 = new Pdf();
//Create a new section in the Pdf object
Section sec1 = pdf1.getSections().add();
//Create a new text paragraph and pass the text to its constructor as argument
Text text1 = new Text(sec1,sb.toString());
sec1.getParagraphs().add(text1);
pdf1.save(new FileOutputStream(new File("test.pdf")));
}catch(java.io.IOException ioe){
System.out.println(ioe.getMessage());
}catch(AsposeBaseException e){
System.out.println(e.getMessage());
}

How can you Insert / Delete Rows Programmatically

Feb 13 2011 04:08 PM | AWS in Code Samples

Do you wish to have worksheets that can be easily updated to keep up with your constantly changing business needs?

Using <a href="http://www.aspose.co...l">Aspose.Cells APIs</a>, you can quickly insert new rows, columns, cells, and worksheets — and just as easily delete them — calling a few methods only and your task is performed with excellence.

While you are creating a new worksheet from scratch or working with an existing worksheet, you might need to add extra rows / columns into your worksheet to accommodate more data or for your specific need.

Alternatively, it can also be required to delete rows / columns from specified positions / locations in the worksheet. To fulfill these requirements, <a href="http://www.aspose.co...ls</a> provides simplest set of APIs that can easily perform your desired task within no time.

There are two methods that Aspose.Cells offers in this regard i.e., InsertRows and DeleteRows, these two methods are optimized related performance and efficient enough to do the job very quickly.

So if you are in need to insert some sets of rows or remove a number of rows, it is recommended that you should always use InsertRows and DeleteRows methods instead of repeatedly using InsertRow and DeleteRow methods in a loop.

<a href="http://www.aspose.co...ls</a> works in the same way as Microsoft Excel does. When rows or columns are added, the contents in the worksheet are shifted to downwards or right side but if rows or columns are removed, the contents in the worksheet will be shifted to upwards or left side. Moreover, the references in other worksheets are updated accordingly upon insertion / deletion of rows.

Following example shows the usage of InsertRows and DeleteRows methods

<strong>[C#]</strong>

//Instantiate a Workbook object.
Workbook workbook = new Workbook();
//Load a template file.
workbook.Open(\\"d:\\test\\MyBook.xls\\");
//Get the first worksheet in the book.
Worksheet sheet = workbook.Worksheets[0];
//Insert 10 rows at row index 2 (insertion starts at 3rd row)
sheet.Cells.InsertRows(2, 10);
//Delete 5 rows now. (8th row - 12th row)
sheet.Cells.DeleteRows(7, 5);
//Save the excel file.
workbook.Save(\\"d:\\test\\out_MyBook.xls\\");

<strong>[VB]</strong>

\\'Instantiate a Workbook object.
Dim workbook As Workbook = New Workbook
\\'Load a template file.
workbook.Open(\\"d:\test\MyBook.xls\\")
\\'Get the first worksheet in the book.
Dim sheet As Worksheet = workbook.Worksheets(0)
\\'Insert 10 rows at row index 2 (insertion starts at 3rd row)
sheet.Cells.InsertRows(2, 10)
\\'Delete 5 rows now. (8th row - 12th row)
sheet.Cells.DeleteRows(7, 5)
\\'Save the excel file.
workbook.Save(\\"d:\test\out_MyBook.xls\\")

<strong>[Java]</strong>

//Instantiate a Workbook object.
Workbook workbook = new Workbook();
//Load a template file.
workbook.open(\\"d:\\test\\MyBook.xls\\");
//Get the first worksheet in the book.
Worksheet sheet = workbook.getWorksheets().getSheet(0);
//Insert 10 rows at row index 2 (insertion starts at 3rd row)
sheet.getCells().insertRows(2, 10);
//Delete 5 rows now. (8th row - 12th row)
sheet.getCells().deleteRows(7, 5,true);
//Save the excel file.
workbook.save(\\"d:\\test\\out_MyBook.xls\\");

Building a Mobile Game in Visual Studio

Feb 13 2011 04:06 PM | AWS in Code Samples

The latest version of Microsoft® Visual Studio® includes a lot of new treats for mobile developers. In addition to new debugging tools and emulators, it includes the Windows® Mobile 5 SDK, .NET® Compact Framework 3.5, and SQL® Server Compact Edition 3.5 out of the box, without additional installs. This walkthrough gives you the code and assets for a fully functional Hangman-style game called "W80 Words" (weighty words), which takes advantage of the new platform and coding environment.

Microsoft Visual Studio 2008 includes a lot of useful features for mobile developers, especially those of the database persuasion. On the one hand, you have the latest and greatest version 3 emulators, Windows Mobile 5 libraries and project templates pre-installed, and unit testing for mobile. (See the Windows Mobile Team Blog for an overview.) On the other hand, you have LINQ, a new syntax for working directly with datasets. But what is the sound of two hands clapping without touching? That's right—silence.

Here's the scoop on LINQ for mobile: technically, LINQ works with .NET Compact Framework 3.5, though with limitations. According to MSDN you get standard query operators, LINQ to DataSet, and LINQ to XML. However, the more useful LINQ to SQL designer is not supported in SQL Server Compact Edition 3.5 (see this thread). Nor will you find any LINQ objects available in your mobile project, despite having a System.Linq reference added by default. In fact, I can find neither details nor code samples regarding LINQ for Mobile on the Internet. Nor can I get any additional information from the fine folks at Microsoft.
