23 May 2017 ... The following is inspired by 'iText in Action - 2nd Edition' by Bruno Lowagie. I am using iTextSharp version 5.4. The code below adds both a text watermark and ... Bump mapping adds lighting detail to a smooth shape, giving it a rough (or bumpy) appearance, without the shape requiring extra polygons. The bump mapping technique based on multitexturing utilizes a texture acting as a normal map. A normal map contains texel values for variations of the shape s surface normals. The map creates patterns of shade and light when applied to the shape. Bump mapping in Java 3D is possible with the COMBINE_DOT3 texture mode, but it s also necessary that the graphics card supports DOT3 texturing. The demos for Java 3D 1.4 and later include a bump mapping example in the dot3/ directory. Alessandro Borges also has an example at http://planeta.terra.com.br/educacao/alessandroborges/java3d.html. Mike Jacobs wrote a JDJ article on bump mapping at http://mnjacobs.javadevelopersjournal.com/ bump_mapping_in_java3d.htm, and Joachim Diepstraten has one at http://java3d.j3d.org/ tutorials/quick_fix/dot3_bumps.html. The Yaarq game by Wolfgang Kienreich utilizes several texturing effects, including bump mapping (http://www.sbox.tugraz.at/home/w/wkien/#demos). create pdf thumbnail image c#: Display PDF thumbnail in WinForms PDF Viewer - Syncfusion add watermark to pdf c# watermark text in all the pdf pages of existing pdf - C# Corner

11 May 2008 ... First off, yes, I know there are other tutorials on how to watermark PDF's with iTextSharp . Unfortunately none of them showed me exactly what I ... The MaskedTextBox control doesn t actually include the functionality needed to validate masks. Instead, the MaskedTextBox control relies on a more generic service provided by another class the MaskedTextProvider class in the System.ComponentModel namespace. You can use the MaskedTextProvider to implement your own masked control, although the process probably won t be easy because it needs you to have fine-grained control over the display and keyboard handling of the control. To create a custom masked control, you need to follow these guidelines: Create a control that maintains an instance of MaskedTextProvider internally. The MaskedTextProvider is stateful it maintains the text that the user has entered into the mask so far. Whenever the custom control receives a key press, determine the attempted action and pass it on to the MaskedTextProvider using methods like Add(), Insert(), Remove(), and Replace(). The MaskedTextProvider will automatically ignore invalid characters. After you ve sent a change to the MaskedTextProvider, call MaskedTextProvider. ToDisplayString() to get the latest text. You can then refresh your custom control. Ideally, you ll update just those characters that have changed, although that often isn t when you re deriving from other controls, in which case you may need to replace all the text in one operation, which might cause flicker. add image watermark to pdf c# Add Watermark in PDF in C# , VB.NET - E-iceblue

After digging into it I found the best way was to add the watermark to each page .... using the following code (perhaps iTextSharp was improved a bit since then. BalloonShopConfiguration.SearchIndex, BalloonShopConfiguration.ResponseGroups); // If any problems occur, we prefer to send back empty result set // instead of throwing exception try { // Load the Amazon response XmlDocument responseXmlDoc = new XmlDocument(); responseXmlDoc.Load(amazonRequest); // Prepare XML document for searching XmlNamespaceManager xnm = new XmlNamespaceManager( responseXmlDoc.NameTable); xnm.AddNamespace("amz", "http://webservices.amazon.com/AWSECommerceService/2005-10-05"); // Get the list of Item nodes XmlNodeList itemNodes = responseXmlDoc.SelectNodes "/amz:ItemSearchResponse/amz:Items/amz:Item", xnm); // Copy node data to the DataTable foreach (XmlNode itemNode in itemNodes) { try { // Create a new datarow and populate it with data DataRow dataRow = responseTable.NewRow(); dataRow["ASIN"] = itemNode["ASIN"].InnerText; dataRow["ProductName"] = itemNode["ItemAttributes"]["Title"] .InnerText; dataRow["ProductImageUrl"] = itemNode["SmallImage"]["URL"] .InnerText; dataRow["ProductPrice"] = itemNode["OfferSummary"] ["LowestNewPrice"]["FormattedPrice"].InnerText; // Add the row to the results table responseTable.Rows.Add(dataRow); } catch { // Ignore products with incomplete information } } } catch { // Ignore all possible errors } return responseTable; } Java 3D has supported two shading languages since version 1.4: OpenGL s GLSL (the default choice in Java 3D) and NVIDIA s Cg. Shader programs can carry out processing at the vertex level (involving their position, normals, color, texture coordinates, per vertex lighting, and others), and at the pixel level (affecting texture and pixel color). They can replicate all the multitexturing effects and can implement many other forms of texturing. It s relatively simple to port existing GLSL and Cg shaders over to Java 3D, although your graphics card must support shader functionality. GLSL only became a core part of OpenGL with version 2.0 in 2004, so it isn t available in older (or less feature-rich) cards. The Java 3D demos include shader examples in glsl_shader/ and cg_shader/. add watermark text to pdf using itextsharp c# Windows Add a text watermark on PDF in C# sample in C# for ...
