Hi,
When a user uploads an image in my image mangement module writen in asp.net and csharp , i need to resize , write some text on top of it and save
This is working fine for all sizes of images but for large images i had to increase the font size used in code
The below code is working for small images(around 500x600)
g.DrawString("test", new System.Drawing.Font("verdana", 14, System.Drawing.FontStyle.Bold),System.Drawing.Brushes.Black, ((thumbNailImg.Width / 2)-5), (thumbNailImg.Height - 20));
But for large images
g.DrawString("test", new System.Drawing.Font("verdana", 35, System.Drawing.FontStyle.Bold),System.Drawing.Brushes.Black, ((thumbNailImg.Width / 2)-5), (thumbNailImg.Height - 20));
i need to change the font size to a larger value, otherwise it wont be readable in the image
Here is what i am doing
1) Resizing image uploaded to 250x200
2) Adding some text over re-sized image
3) Saving it
images sized around 500x600 text is readble but large images i need to change font size
I want to make font size fixed and write text on top of that with text in the image readable any idea how to do this
complete code listing is shown below
String UploadedFile = MyFile.PostedFile.FileName;
int ExtractPos = UploadedFile.LastIndexOf("\\") + 1;
//to retrieve only Filename from the complete path
String UploadedFileName = UploadedFile.Substring(ExtractPos,UploadedFile.Length - ExtractPos);
// Display information about posted file. Div is invisible by default
FileName.InnerHtml =UploadedFileName;
MyContentType.InnerHtml = MyFile.PostedFile.ContentType;
ContentLength.InnerHtml = MyFile.PostedFile.ContentLength.ToString();
FileDetails.Visible = true; //div is made visible
// Save uploaded file to server at the in the Pics folder
MyFile.PostedFile.SaveAs(Request.PhysicalApplicationPath + "images\\" + UploadedFileName );
//thumbnail creation starts
//Read in the image filename whose thumbnail has to be created
String imageUrl = UploadedFileName;
//Read in the width and height
int imageHeight = 200;
int imageWidth = 250;
//You may even specify a standard thumbnail size
//int imageWidth = 70;
//int imageHeight = 70;
if (imageUrl.IndexOf("/") >= 0 || imageUrl.IndexOf("\\") >= 0)
{
//We found a / or \
Response.End();
}
//the uploaded image will be stored in the Pics folder.
//to get resize the image, the original image has to be accessed from the
//Pics folder
imageUrl = "images/" + imageUrl;
System.Drawing.Image fullSizeImg = System.Drawing.Image.FromFile(Server.MapPath(imageUrl));
System.Drawing.Image.GetThumbnailImageAbort dummyCallBack = new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);
double aspectRatio = Convert.ToDouble(imageWidth) / Convert.ToDouble(imageHeight);
//int maxWidth = 250;
//int maxHeight = 250;
//if (aspectRatio <= 1 && imageWidth > maxWidth)
//{
// imageWidth = maxWidth;
// imageHeight = Convert.ToInt32(Math.Round(imageWidth / aspectRatio));
//}
//else if (aspectRatio > 1 && imageHeight > maxHeight)
//{
// imageHeight = maxHeight;
// imageWidth = Convert.ToInt32(Math.Round(imageHeight * aspectRatio));
//}
System.Drawing.Image thumbNailImg = fullSizeImg.GetThumbnailImage(imageWidth, imageHeight, dummyCallBack, IntPtr.Zero);
//We need to create a unique filename for each generated image
DateTime MyDate = DateTime.Now;
String MyString = MyDate.ToString("ddMMyyhhmmss") + ".png";
System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(thumbNailImg);
g.DrawString("test", new System.Drawing.Font("verdana", 14, System.Drawing.FontStyle.Bold),System.Drawing.Brushes.Black, ((thumbNailImg.Width / 2)-5), (thumbNailImg.Height - 20));
//Save the thumbnail in Png format. You may change it to a diff format with the ImageFormat property
thumbNailImg.Save(Request.PhysicalApplicationPath + "images\\" + MyString, ImageFormat.Png);
thumbNailImg.Dispose();
g.Dispose();
fullSizeImg.Dispose();
//Display the original & the newly generated thumbnail
Image1.AlternateText = "Original image";
Image1.ImageUrl = "~\\images\\" + UploadedFileName;
Image2.AlternateText = "Thumbnail";
Image2.ImageUrl = "~\\images\\" + MyString;
Thanks in advance

Hi all i have a problem opening a page in a new browser windows when i click on a button in a Grid view Control. The page opens every thing fine but the it reloads my previous page where the button is. Is there a way to stop this from happening? All your Help Would Really BE appreciated.
Thanks In advance!

This is happening because of the postback that the button is creating. Just add "return false;" to your window.open() code. It will solve your problem.

How do you get from your application to the database? Are you connecting to the correct database? Are you connecting with the correct credentials? Is the stored procedure in a different schema to the one you are using?

Check your connectionstring with database,maybe your dataabse connectionstring in your project is different from database which exists that stored procedure.

The problem is with your connection string, validate your connection string and check its refers to the proper database or not.
Thanks

I'm curious about what was wrong with my response. I was merely attempting to illicit more information from you in order to attempt to help you with your very vague issue. If you don't want my help, then ignore my message. Do not send me narky messages and do not, I suspect, vote my answer as a "Bad Answer".

What were the issues you had with these? I try to be helpful where I can. I try to maintain a sense of humour and keep the atmosphere light. If you have any issues then let me know. Don't send messages, delete them, and vote me down without at least some sort of explanation - That is the utmost in rudeness. It would be like spitting on me as you walked past in the street.

Avoid deleting a message after it has gathered replies. It does leave the forum face cluttered.

When I move a directory the session gets expiered. Can anybody help me out in find what is going wrong in the process of moving the directory. My session mode is 'InProc' and expiry timeout is '90' minutes. And it takes maximum 5 seconds to move the directory.
Thanks in advance.

Why are you moving a directory ? That sounds pretty insane to do on a website.

Why is it required? What is the overall purpose, not the micro-goal.

What is the overall task that this directory move fits in to. Understanding the bigger picture will probably result in a better solution all round.

Hello Colin,
thanks for your reply. Actually I need to rename the directory folder by keeping all the content of that folder as it was.
Thanks,
Arindam

That does not answer my question. What is the overall goal of what you are trying to do.
Renaming a folder does not bring significant benefits to anyone in and of itself.
What is the content? why does it need to be kept the same? why does the name have to change? What prompts the need to rename the folder? Why is that important?
I'm looking for the big picture. I may not be able to help with this precise issue, but I may be able to help provide a different strategy for achieving the overall goal.

Arindam,
Are you moving directory with in the current ASP.NET application ? if yes then its obvious, because it will recompile the application and will recycle the worker process, causes session expiry.
So please check it.
Thank you !!

Hello Abhijit,
thanks for your reply. But is there any way we can handle the session expired issue?
Thanks

Move the session out of process. That way, when the process is recycled it isn't lost. However, this means that you are going to have to make sure that everything you put in the session is serialisable.
The two main choices for moving the seesion out of process are a state server, or by using SQL State management. Both have slightly different issues which may or may not work for you.

Just change the session mode to OutProc and store the Session data either in StateServer or SQL Server.
Hope This article may help you.
