Hi
I currently have a form for people to fill in, with this they need to uplaod a profile picture of themselves. At the moment I have the following code which uploads the image, but i want to be able to resize the image to a certin size. Ive seen resizing help on the web, but most of these seem to be large/thumbnail codes and im getting a bit boggled!

Boolean fileOK = false;
            String path = Server.MapPath("~/uploadedconsultantimages/");
            if (UploadImage.HasFile)
            {
                String fileExtension =
                    System.IO.Path.GetExtension(UploadImage.FileName).ToLower();
                String[] allowedExtensions = 
                { ".gif", ".png", ".jpeg", ".jpg" };
                for (int i = 0; i < allowedExtensions.Length; i++)
                {
                    if (fileExtension == allowedExtensions[i])
                    {
                        fileOK = true;
                    }
                }
            }

            if (fileOK)
            {
                try
                {
                    UploadImage.PostedFile.SaveAs(path
                        + UploadImage.FileName);
                    FileUploaded.Text = "File uploaded!";
                }
                catch (Exception ex)
                {
                    FileUploaded.Text = "File could not be uploaded.";
                }
            }
            else
            {
                FileUploaded.Text = "Cannot accept files of this type.";
            }

Any help would be appreciated. I working in c# .net2 Smile | :)

Thanks

I haven't played around with the Upload stuff yet so not sure whether you can access the uploaded file in memory and resize it before saving it.

If not, then you simply need to use something like

Boolean fileOK = false;<br />
            String path = Server.MapPath("~/uploadedconsultantimages/");<br />
            if (UploadImage.HasFile)<br />
            {<br />
                String fileExtension =<br />
                    System.IO.Path.GetExtension(UploadImage.FileName).ToLower();<br />
                String[] allowedExtensions = <br />
                { ".gif", ".png", ".jpeg", ".jpg" };<br />
                for (int i = 0; i < allowedExtensions.Length; i++)<br />
                {<br />
                    if (fileExtension == allowedExtensions[i])<br />
                    {<br />
                        fileOK = true;<br />
                    }<br />
                }<br />
            }<br />
<br />
            if (fileOK)<br />
            {<br />
                try<br />
                {<br />
                    UploadImage.PostedFile.SaveAs(path<br />
                        + UploadImage.FileName);<br />
<br />
					Bitmap source = Bitmap.FromFile(path + UploadImage.FileName);<br />
					Bitmap result = new Bitmap(250,250);<br />
					using(Graphics g = Graphics.FromImage((Image)result);<br />
					g.DrawImage(source, 0, 0, 250, 250);<br />
					result.Dispose();<br />
					source.Dispose();<br />
					result.Save(path + UploadImage.FileName);<br />
<br />
                    FileUploaded.Text = "File uploaded!";<br />
                }<br />
                catch (Exception ex)<br />
                {<br />
                    FileUploaded.Text = "File could not be uploaded.";<br />
                }<br />
            }<br />
            else<br />
            {<br />
                FileUploaded.Text = "Cannot accept files of this type.";<br />
            }

This is untested, but basically "should" resize the uploaded image to 250x250.

Thanks, im still getting build errors though:

Error 1 Cannot implicitly convert type 'System.Drawing.Image' to 'System.Drawing.Bitmap'. An explicit conversion exists (are you missing a cast?)

Bitmap source = Bitmap.FromFile(path + UploadImage.FileName);

Thanks

Bitmap source = (Bitmap)Bitmap.FromFile(path + UploadImage.FileName); try this
Does it will help you ?
Bitmap.FromFile(path + UploadImage.FileName);
return type is Image Why you want to convert it into Bitmap
What you want to do ?

Thanks and Regards

pass argument to crystal report

18-Apr-07 4:51

Ill give it a go, what i want to do is allow the user to upload a picture of themselves which is then resized automatically before it is saved. The image is just getting saved to file rather than in a database.

Thanks

J# is being discontinued. Therefore it will not exist soon. Learning a technology that is about to cease to exist is pointless.

This sounds just like the hundred or so other homework questions people post here daily.

Here's a tip - try it yourself. If you get stuck on any specific part feel free to come back and ask for specific help.
