Image Handeling in C#

Introduction

While creating my Student Management System I have to deal with student image & there my scenario is to store student image to a local folder situated in my project namespace after resizing and its name (only) to database, in order to be lighten the database.. So, I do search for that almost 5 days and finally I succeeded and I m sharing it with you. Have a look...

First of all you have to import two extra libraries:

using System.Drawing.Imaging;
using System.Drawing.Drawing2D; 

Write the following line globally in the form:

public Size OriginalImageSize { get; set; } 

Now create some functions:

static Image ScaleByPercent(Image imgPhoto)
{    
    int sourceWidth = imgPhoto.Width;     //store original width of source image.
    int sourceHeight = imgPhoto.Height;   //store original height of source image.
    int sourceX = 0;        //x-axis of source image.
    int sourceY = 0;        //y-axis of source image.
    int destX = 0;          //x-axis of destination image.
    int destY = 0;          //y-axis of destination image.
    
    Bitmap bmPhoto;

    if (sourceWidth > sourceHeight)
    //for cheking whether slected image orizontally or vertically oriented
    {
        bmPhoto = new Bitmap(300, 200, PixelFormat.Format24bppRgb);
    }
    else
    {
        bmPhoto = new Bitmap(200, 300, PixelFormat.Format24bppRgb);
    }

    //Create a graphics object and set quality of graphics.
    Graphics grPhoto = Graphics.FromImage(bmPhoto);
    grPhoto.InterpolationMode = InterpolationMode.HighQualityBicubic;
    //Draw image by using DrawImage() method of graphics class.
    int bmPhotowidth=bmPhoto.Width;
    int bmPhotoHeight = bmPhoto.Height;
    if (bmPhotowidth > bmPhotoHeight)
    {
        grPhoto.DrawImage(imgPhoto, new Rectangle(destX, destY, 300, 200), 
          new Rectangle(sourceX, sourceY, sourceWidth, sourceHeight), GraphicsUnit.Pixel);

    }
    else
    {
        grPhoto.DrawImage(imgPhoto, new Rectangle(destX, destY, 200, 300), 
          new Rectangle(sourceX, sourceY, sourceWidth, sourceHeight), GraphicsUnit.Pixel);

    }
    grPhoto.Dispose();  //Dispose graphics object.
    return bmPhoto;
}

Now use button "browsebtn_click" event to select image from computer:

private void button2_Click(object sender, EventArgs e)
{
    OpenFileDialog opd = new OpenFileDialog();
    
    if (opd.ShowDialog()==DialogResult.OK)
    {
        pictureBox2.ImageLocation = opd.FileName;
        int picwidth = pictureBox2.Image.Width;
        int picheight = pictureBox2.Image.Height;
        string imgsize = "Original Image Width = " + 
                 picwidth + " And Height = " + picheight;
        OriginalImageSize = new Size(picwidth, picheight);
    }
}

Now write a new function to store the name into database. Here I am just showing you to save image to folder and get the file name that u can store to database. I guess you know the Insert Query.. Smile | :)

private String imageUpload()
{
    string imagepath = pictureBox2.ImageLocation.ToString();
    string picname = imagepath.Substring(imagepath.LastIndexOf('\\'));
    //MessageBox.Show(picname);

    Image scaledImage = ScaleByPercent(pictureBox2.Image);
    pictureBox2.Image = scaledImage;

    string path = Application.StartupPath.Substring(0, Application.StartupPath.LastIndexOf("bin"));
    Bitmap imgImage = new Bitmap(pictureBox2.Image);    //Create an object of Bitmap class/
    if (!Directory.Exists(path + "\\images\\"))
    {
        Directory.CreateDirectory(path + "\\images\\");
        imgImage.Save(path + "\\images\\" + picname);
    }
    else
    {
        imgImage.Save(path + "\\images\\" + picname);
    }
    return picname;//this file name can be accesible to your save button click event.

}

So, there you go. Hope you like this article.  Smile | :)
