Introduction

This article explains how to Write a Text On Image Using Asp.Net & C#.In this article i am using some common library functions and methods.

Image Class &Bitmap Class

The Image class is one of the example of Abstract Class The Bitmap class is an implementation of the Image class and it inherits from the Abstract Image class. After implementation we can get the Image Class functionality in Bitmap Class.

C# Code

The below code is using for Write a Text On Image.We can change the below functionalities based on our requirement.

//creating a image object System.Drawing.Image bitmap = (System.Drawing.Image)Bitmap.FromFile(Server.MapPath("onam.jpg")); // set image //draw the image object using a Graphics object Graphics graphicsImage = Graphics.FromImage(bitmap); //Set the alignment based on the coordinates StringFormat stringformat = new StringFormat(); stringformat.Alignment = StringAlignment.Far; stringformat.LineAlignment = StringAlignment.Far; StringFormat stringformat2 = new StringFormat(); stringformat2.Alignment = StringAlignment.Center; stringformat2.LineAlignment = StringAlignment.Center; //Set the font color/format/size etc.. Color StringColor = System.Drawing.ColorTranslator.FromHtml("#933eea");//direct color adding Color StringColor2 = System.Drawing.ColorTranslator.FromHtml("#e80c88");//customise color adding string Str_TextOnImage = "Happy";//Your Text On Image string Str_TextOnImage2 = "Onam";//Your Text On Image graphicsImage.DrawString(Str_TextOnImage, new Font("arial", 40, FontStyle.Regular), new SolidBrush(StringColor), new Point(268, 245), stringformat); Response.ContentType = "image/jpeg"; graphicsImage.DrawString(Str_TextOnImage2, new Font("Edwardian Script ITC", 111, FontStyle.Bold), new SolidBrush(StringColor2), new Point(145, 255), stringformat2); Response.ContentType = "image/jpeg"; bitmap.Save(Response.OutputStream, ImageFormat.Jpeg); Graphics & Bitmap

A Bitmap is an object used to work with images defined by pixel data and you can draw the image object using a Graphics object.Check the below code.

//creating a image object System.Drawing.Image bitmap = (System.Drawing.Image)Bitmap.FromFile(Server.MapPath("onam.jpg")); // set image //draw the image object using a Graphics object Graphics graphicsImage = Graphics.FromImage(bitmap); Formatting the string

Change Text Alignment based on the coordinates

//Set the alignment based on the coordinates StringFormat stringformat = new StringFormat(); stringformat.Alignment = StringAlignment.Far; stringformat.LineAlignment = StringAlignment.Far; StringFormat stringformat2 = new StringFormat(); stringformat2.Alignment = StringAlignment.Center; stringformat2.LineAlignment = StringAlignment.Center; Text On Image

Set the font color,size,format.

string Str_TextOnImage = "Happy";//Your Text On Image string Str_TextOnImage2 = "Onam";//Your Text On Image graphicsImage.DrawString(Str_TextOnImage, new Font("arial", 40, FontStyle.Regular), new SolidBrush(StringColor), new Point(268, 245), stringformat); Response.ContentType = "image/jpeg"; graphicsImage.DrawString(Str_TextOnImage2, new Font("Edwardian Script ITC", 111, FontStyle.Bold), new SolidBrush(StringColor2), new Point(145, 255), stringformat2); Response.ContentType = "image/jpeg"; String Color

Adding the string color in two way..

Color StringColor = System.Drawing.Color.Red;//direct color adding Color StringColor = System.Drawing.ColorTranslator.FromHtml("#933eea");//customise color adding Important Section Namespace using System.Drawing;using System.Drawing.Imaging;

The above namespace is contain Graphics,Bitmaps,Image Editing and Alignment,etc libraries.

OutPut
