Hi all,
I am trying resize an image using the following code.
//resize image
System.Drawing. Image ImageUpload =
System.Drawing. Image.FromFile( String.Concat(S erver.MapPath(F ilePath),ImageN ame));
// create the actual thumbnail image
System.Drawing. Image ThumbnailImage =
ImageUpload.Get ThumbnailImage( 250,ImageUpload .Height * 250 /
ImageUpload.Wid th, new
System.Drawing. Image.GetThumbn ailImageAbort(T humbnailCallbac k),
IntPtr.Zero);
ThumbnailImage. Save(ImageName) ); //ie: test.jpg
However i keep getting this error:
Exception Details: System.Runtime. InteropServices .ExternalExcept ion: A
generic error occurred in GDI+.
Any one have any ideas?
Cheers,
Adam

Take a look at this... http://www.howtodothings.com/compute...humbnails.html
I seem to remember having to process it from memory. If I recall correctly
the GDI+ error only occurred if I tried to process an image from disk that I
had only just saved, which is why I decided to process from memory instead.

I am struggling to create a PHP function that would take a specified
image (JPG, GIF or PNG) from a link, and resize it down to a thumbnail
so it will always fit in a 200x250 space. I am hoping not to have it
inserted or read from a database to do this function. Can it be done &
someone please help me?

I am storing an image in an SQL database and have one field as an image
datatype. I am also using a webservice to transport data.
I want to be able to resize the image and pass back a thumbnail image in a
byte of what is in the database.
I also want to be able to display this image in an <asp:image></asp:image>
control.
Is there any way to do this? Most of the examples that I've seen have used

Hi,
I want to resize an image on my server.
I tried a lot of samples... but all the time it does resize and saves the
images but I can not view the image insize a webbrowser.
With an imageviewer (desktop application) I can view the image. I believe
there is something wrong with the maximum colors...
This is what I have now...
Image originalBitmap = Image.FromFile("C:\temp\image.jpg", true);

Hi all,
I've a classic upload form where people may select images on their computer
to send on my website.
Since this is done by people not very confortable with computers, some sent
pictures are very huge (3MB) and I do resize them anyway since I only allow
500px wide pictures.
Instead of letting people upload the 3MB file then resize it on the server,

I am looking for a way to display images with different aspect ratio into
frames with fixed width and height, the problem is some images will look
distorted if they are forced into fixed frame due to differnt aspect ratio.
Some graphic designer suggests me to keep the aspect ratio of the original
graphic and pad the graphic with empty space to fit into the frame. One
example, the fixed frame is 100x60 and the image is 120x120, I...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
