Convert Scanned PDF to OCR (Textsearchable PDF) using C# ... Tesseract : Tesseract is probably the most accurate open source OCR engine available. Figure 4-8. Adding an ID column as the primary key of Department The primary key column is named DepartmentID. We ll use the same naming convention for primary key columns in the other data tables we ll create. There are two main reasons why it s better to create a separate numerical primary key column than to use Name (or another existing column) as the primary key: Performance: The database engine handles sorting and searching operations much faster with numerical values than with strings. This becomes even more relevant in the context of working with multiple related tables that need to be frequently joined (you ll learn more about this in 5). Department name changes: If you need to rely on the ID value being stable in time, creating an artificial key (in the form of an additional ID column) solves the problem because it s unlikely you ll ever need to change the ID. In Figure 4-8, the primary key is composed of a single column, but this is not a requirement. If the primary key is composed of more than one column, the group of primary key columns (taken as a unit) is guaranteed to be unique (but the individual columns that form the primary key can have repeating values in the table). In 5, you ll see an example of a multivalued primary key. For now, it s enough to know that they exist. c# ocr pdf: .NET OCR Library API for Text Recognition from Images in C# & VB ... tesseract c# pdf Scanned PDF to OCR (Textsearchable PDF) using C# - CodinGame

May 24, 2018 · Hello, I use the example "Creating a searchable Pdf" found here: https://github.com/tvn-cosine/tesseract.net/wiki/Creating-a-searchable-Pdf I ... private void Form1_Paint(PaintEventArgs e) { TextFormatFlags flags = TextFormatFlags.Bottom | TextFormatFlags.EndEllipsis; TextRenderer.DrawText(e.Graphics, "This text drawn with GDI.", this.Font, new Rectangle(10, 10, 100, 50), SystemColors.ControlText, flags); } The Windows Forms team faced a bit of a dilemma when they created the TextRenderer namely, whether they should use it for better rendering in the standard .NET controls, even though it could alter existing applications (due to subtly different measuring and wrapping conventions). They settled on allowing controls to decide what rendering behavior to use based on a new Control.UseCompatibleTextRendering property. This property defaults to true, which means that the control should use the same rendering as it did in .NET 1.x. If you set this property to false, however, the control should switch to the TextRenderer. Of course, it s up to the control itself to check this property in its painting code and use the TextRenderer simply setting the property on a control that doesn t use it has no effect. However, you ll notice that the .NET controls do respect the UseCompatibleTextRendering property. To have the least effect on existing applications, UseCompatibleTextRendering defaults to true. Rather than set this property for each control in your application, you can call the Application. SetCompatibleTextRenderingDefault() method. In fact, every new Windows application created with Visual Studio 2005 automatically inserts a call to this method that passes an argument of false, thereby upgrading all standard controls to the TextRenderer. add watermark text to pdf using itextsharp c#: Add Watermark in PDF in C# , VB.NET - E-iceblue c# ocr pdf to text Extracting Text from an Image Using Tesseract in C# - CodeGuru

As you ve learned, the Graphics class allows you to draw all the basic ingredients lines, rectangles, ellipses, arcs, polygons, curves, and strings of text. The GraphicsPath allows you to combine a group of these elements into a single unit. You can then draw them all at once, or perform other tasks like hit testing. To build a GraphicsPath object, you simply create a new instance, and use the methods in Table 7-5 to add all the required elements. Here s an example that creates a GraphicsPath made up of an ellipse and a rectangle: GraphicsPath path = new GraphicsPath(); path.AddEllipse(0, 0, 100, 50); path.AddRectangle(new Rectangle(100, 50, 100, 50)); These two shapes can overlap, but they don t need to. Either way, both shapes are merged into one logical entity for future manipulation. Once you ve created the GraphicsPath object, you can copy it onto the drawing surface using the DrawPath() and FillPath() methods of the Graphics object: e.Graphics.DrawPath(pen, path); When you re finished, remember to clean up by disposing the path: path.Dispose(); Using the GraphicsPath, you also can create a solid-filled figure out of line segments. To do this, you first call the StartFigure() method. Then you add the required curves and lines using c# ocr pdf to text Extracting Text from an Image Using Tesseract in C# - CodeGuru
