I found the solutions of image re-sizing at run-time in asp.net
use this code to obtain re-sized image:
SqlCommand cmd = new SqlCommand("select ProductPicture from ProductDetails where Id=" + pdctid + "", con);
byte[] product = (byte[])cmd.ExecuteScalar();
MemoryStream stream = new MemoryStream(product);
Response.BinaryWrite(ResizeUploadedImage(stream));
private byte[] ResizeUploadedImage(Stream streamToResize)
{
byte[] resizedImage;
using (System.Drawing.Image orginalImage = System.Drawing.Image.FromStream(streamToResize))
{
ImageFormat orginalImageFormat = orginalImage.RawFormat;
int orginalImageWidth = orginalImage.Width;
int orginalImageHeight = orginalImage.Height;
int resizedImageWidth = 150; // Type here the width you want
int resizedImageHeight = 90; // Type here the hight you want
using (Bitmap bitmapResized = new Bitmap(orginalImage, resizedImageWidth, resizedImageHeight))
{
using (MemoryStream streamResized = new MemoryStream())
{
bitmapResized.Save(streamResized, orginalImageFormat);
resizedImage = streamResized.ToArray();
}
}
}
return resizedImage;
}
