resizing images

[mjd3000]

I am displaying images from a database using the code below.

Is there any way I can resize the images before rendering them?



public void showSelectedImage(string strEncodedImage)
{
Response.Clear();
Response.ContentType = "image/jpeg";

System.Drawing.Image image = retrieveImage(strEncodedImage);
image.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
}

private System.Drawing.Image retrieveImage(string strEncodedImage)
{
System.Drawing.Image image = null;

byte[] imageData = Convert.FromBase64String(strEncodedImage);

MemoryStream memStream = new MemoryStream(imageData);
image = System.Drawing.Image.FromStream(memStream);

return image;
}

in retrieveImage, once yo have the full size image in memory, call the image.GetThumbnailImage() method, passing in the new size you want.

But dont forget that unless all your images are uniform in the database you may need to take into account the aspect ratios.
