about image rotating

Hello all, how could I rotate a server side image in asp.net and show it in
web page? Thanks.

Well, I'm not going to write the whole function for you, but you basically
need to create an *.aspx page that returns an image/gif. In the Load event,
you will simply use the classes in the System.Drawing namespace to rotate
it. If you have never created an *.aspx that returns an image/gif, you
basically use the Save() method of a Bitmap to output the image to the
Response.Output Stream like the following:

mybitmap.Save(R esponse.OutputS tream, ImageFormat.Gif )

I'm not going to going into the other details of the steps you will need to
take, but most of them are reasonably simple, and if you can find a good
website I think you'll be able to figure it out. Good Luck!

Hi Michael,

From your description, you're wantting to display some image files(at
server-side) as rotated format on ASP.NET web page, correct?

If so, I think the proper means is use the .NET GDI+ classes to perform
transforming on the certain images. You can generate an rotated image
stream and output it on page(via an httphander or page...)

Here are some good web articles which has introduced some code and examples
on GDI+ image transformation:

#Matrix Transformation of Images in C#, using .NET GDI+
http://www.codeproject.com/KB/GDI-pl...formation.aspx

#Image Transformation in C# with GDI+

Also, if you're not familar with emiting image stream via httphandler in
ASP.NET, here are some tech articles on this:

if you just want to rotate or flip it by the standard 90/180/270 then
you could try

System.Drawing. Image image =
System.Drawing. Image.FromFile( fileInPath);
image.RotateFli p(RotateFlipTyp e.xxxxx);
image.Save(file OutPath)
Jun 27 '08 #4
Thanks to everyone's response and informaton. Image.RotateFli p resolved the
issue.
