Compressed Image Uploading

vijayaasri palaniappan

Hi,

I want to compress my image while I'm Uploading. With the help of the C#Corner Website I got that code. But, I facing the Issue in

Stream strm = ImageFile.PostedFile.InputStream; // Here It shows error in Input stream
using (var image = System.Drawing.Image.FromStream(strm))
{

My Full code is here :

public ActionResult DetailsEdit(EmployeeData___TBL e, string id, HttpPostedFileBase ImageFile)
{
var data = Session["userid"].ToString();
if (e.ImageFile != null)
{
string filename = Path.GetFileNameWithoutExtension(e.ImageFile.FileName);
string extension = Path.GetExtension(e.ImageFile.FileName);
HttpPostedFileBase postedfile = e.ImageFile;
int length = postedfile.ContentLength;
if (extension.ToLower() == ".jpg" || extension.ToLower() == ".jpeg" || extension.ToLower() == ".png")
{
if (length <= 1000000)
{
filename = filename + extension;
Stream strm = ImageFile.PostedFile.InputStream;
using (var image = System.Drawing.Image.FromStream(strm))
{
int newWidth = 240; // New Width of Image in Pixel
int newHeight = 240; // New Height of Image in Pixel
var thumbImg = new Bitmap(newWidth, newHeight);
var thumbGraph = Graphics.FromImage(thumbImg);
thumbGraph.CompositingQuality = CompositingQuality.HighQuality;
thumbGraph.SmoothingMode = SmoothingMode.HighQuality;
thumbGraph.InterpolationMode = InterpolationMode.HighQualityBicubic;
var imgRectangle = new Rectangle(0, 0, newWidth, newHeight);
thumbGraph.DrawImage(image, imgRectangle);
e.ProfileImage = "~/AppFiles/" + filename;
filename = Path.Combine(Server.MapPath("~/AppFiles/"), filename);
e.ImageFile.SaveAs(filename);
// db.Entry(e).State = EntityState.Modified;
// int a = db.SaveChanges();
db.SP_EditUserInfo(data, e.Name, e.EmailID, e.PhoneNo, e.Address, e.ProfileImage);
//TempData["UpdateMessage"] = "";
ModelState.Clear();
return RedirectToAction("Details", "Home");
}
}
}
else
{
e.ProfileImage = Session["Image"].ToString();
//db.SP_UpdateUserInfo(e.UserId, e.Name, e.EmailID, e.PhoneNo, e.Address, e.ProfileImage);
//db.Entry(e).State = EntityState.Modified;
ModelState.Clear();
return RedirectToAction("List", "Home");
}
return View();
}
}

Accepted answer
if you want to save thumbimage in database then change
db.SP_EditUserInfo(data, e.Name, e.EmailID, e.PhoneNo, e.Address, e.ProfileImage);
to this
db.SP_EditUserInfo(data, e.Name, e.EmailID, e.PhoneNo, e.Address, filename);

You can use LEADTOOLS Imaging Pro SDK technology in your application.
https://www.leadtools.com/sdk/products/imaging-pro
You can leverage the RasterCodecs class, which allows you to load any LEADTOOLS supported raster image format and export to any LEADTOOLS supported raster image format. You can utilize the RasterImageFormat enumeration and QualityFactor property, to indicate the image compression type and to specify the tradeoff between quality and compression.
https://www.leadtools.com/help/sdk/v21/dh/to/compression-quality-factors.html

I am unaware of the file format you are using, so the code below uses JPEG:
```
// Load in source image
using (RasterCodecs _codecs = new RasterCodecs())
using (RasterImage _image = _codecs.Load(@"FILE PATH TO INPUT IMAGE"))
{
    // QualityFactor takes values between 2 to 255
    // 2 being highest quality, 255 being most compression
    _codecs.Options.Jpeg.Save.QualityFactor = 100;
    _codecs.Save(_image, @"FILE PATH TO OUTPUT IMAGE", RasterImageFormat.Jpeg, 0);
}
```

copy paste and test
public ActionResult DetailsEdit(EmployeeData___TBL e, string id, HttpPostedFileBase ImageFile)
{
    var data = Session["userid"].ToString();
    if (ImageFile != null)
    {
        string filename = Path.GetFileNameWithoutExtension(ImageFile.FileName);
        string extension = Path.GetExtension(ImageFile.FileName);

        int length = ImageFile.ContentLength;
        if (extension.ToLower() == ".jpg" || extension.ToLower() == ".jpeg" || extension.ToLower() == ".png")
        {
            if (length <= 1000000)
            {
                filename = filename + extension;
                Stream strm = ImageFile.InputStream;
                using (var image = System.Drawing.Image.FromStream(strm))
                {
                    int newWidth = 240; // New Width of Image in Pixel
                    int newHeight = 240; // New Height of Image in Pixel
                    var thumbImg = new Bitmap(newWidth, newHeight);
                    var thumbGraph = Graphics.FromImage(thumbImg);
                    thumbGraph.CompositingQuality = CompositingQuality.HighQuality;
                    thumbGraph.SmoothingMode = SmoothingMode.HighQuality;
                    thumbGraph.InterpolationMode = InterpolationMode.HighQualityBicubic;
                    var imgRectangle = new Rectangle(0, 0, newWidth, newHeight);
                    thumbGraph.DrawImage(image, imgRectangle);
                    filename = Path.Combine(Server.MapPath("~/AppFiles/"), ImageFile.FileName);

                    ImageFile.SaveAs(filename);
                    // db.Entry(e).State = EntityState.Modified;
                    // int a = db.SaveChanges();
                    db.SP_EditUserInfo(data, e.Name, e.EmailID, e.PhoneNo, e.Address, e.ProfileImage);
                    //TempData["UpdateMessage"] = "";
                    ModelState.Clear();
                    return RedirectToAction("Details", "Home");
                }

            }
        }
        else
        {
            e.ProfileImage = Session["Image"].ToString();
            //db.SP_UpdateUserInfo(e.UserId, e.Name, e.EmailID, e.PhoneNo, e.Address, e.ProfileImage);
            //db.Entry(e).State = EntityState.Modified;
            ModelState.Clear();

Thank You So Much Sachin Singh.

How we find the image is resized or not ?

why are you using postedFile when you are directly getting file, instead use this
Stream strm = ImageFile.InputStream;

Hi Salman,

Here is my error

'HttpPostedFile' does not contain a definition for 'PostedFile' and no accessible extension method 'PostedFile' accepting a first argument of type 'HttpPostedFileBase' could be found (are you missing a using directive or an assembly refernce?)

Thanks in advance.
