Start and Run Watermark Adding Project in C#
This part mainly provides C#.NET developers with detailed guide on opening and running a C# application for adding watermark on image. Specific tips are listed below. (For VB.NET developers, please go to
add watermark to images in VB.NET. Want to use image and document watermark function in WinForms or web application, please go to add watermark to images in WinForms or web document images watermark adding.)
- Start your Visual Studio 2005 or any greater version;
- Create a Windows application in Visual C# programming language;
- Copy your RasterEdge license text to the "bin" file of the created C# Windows application folder;
- Embed following .NET imaging libraries to C#.NET class project;
- RasterEdge.Imaging.Basic.dll
- RasterEdge.Imaging.Processing.dll
- Run following using namespace within C# project:
using System.IO;
using System.Drawing.Printing;
using RasterEdge.Imaging;
using RasterEdge.Imaging.Processing;
Method to Add Watermark on C# Project Image
As you can see from following image watermark adding method, using this C# imaging library, you are able to create and customize the image watermark by setting the font style, changing the brush color & opacity and adjusting watermark width & height in C# project.
public void CreateWatermark(string s, Font font, Brush brush, PointF point);
C# Demo Code for Adding Watermark on Image
Both developers and end users can use following C# demo code directly in your C# applications for image watermark creating.
using System.IO;
using System.Drawing.Printing;
using RasterEdge.Imaging;
using RasterEdge.Imaging.Processing;
RasterEdgeImaging Image = new RasterEdgeImaging();
//Create an instance of Image and load an existing image
using (Image image= Image.LoadImageFromFile(@"C:\1.bmp"));
{
Graphics graphics = new Graphics(image);
RasterEdgeImaging.Font font = new RasterEdgeImaging.Font("Times New Roman", 16, FontStyle.Bold);
RasterEdgeImaging.Brushes.SolidBrush brush=new RasterEdgeImaging.Brushes.SolidBrush();
brush.Color=Color.Black;
brush.Opacity=100;
image.CreateWatermark("watermark", font, brush, new PointF(image.Width/2, image.Height/2));
image.Save(@"C:\1-watermark.bmp");
}
More C#.NET Image Processing Functionalities
All the .NET image editing functions can be realized when correctly integrated within C#.NET application.
Within .NET Imaging Processing SDK, users are capable of using its excellent functionalities in C#.NET, VB.NET, web ASP and .NET Windows Forms platforms. Specific processing operations are: resizing, rotating, adjusting brightness and contrast, region of interest (ROI) support for primary shapes, most complete color space support, powerful and reliable color reduction products, image encryption decryption, and even more.
