Load Image from Stream

pinbot

Is there a way to load an image from a stream?

I can generate a URL that will thumbnail a photo on the fly.

In FR Studio I would do an OnBeforePrint and some WebClient C# to load into the image just before displaying.

IfrxPictureView pict = (IfrxPictureView)Sender;
...
pict.LoadViewFromStream(s);


That way the image was already resized before becoming part of the report.

In Fr.Net I see MyPicture.Image.Save which will take a stream but no corresponding MyPicture.Image.Load

Thanks,

Bryan

Hello,

Here is an example how you can load an image from a file:

    private void Picture1_BeforePrint(object sender, EventArgs e)
    {
      Picture1.Image = new Bitmap(@"c:\test.png");
    }

using another overloads of Bitmap constructor, you may load from stream.

Actually it was even easier than that.

I just set ImageLocation to be my full URL in the BeforePrint and FR.NET loaded the picture for me!


private void PropertyPicture_BeforePrint(object sender, EventArgs e)
{
String URL;

URL = "http://www.xxx.xxx/aptpicture/?"; + ((String)Report.GetColumnValue("PropSheetQuery.ApartmentPictureURL"));
URL += "&h=" + ((int)PropertyPicture.Height).ToString();
URL += "&w=" + ((int)PropertyPicture.Width).ToString();

PropertyPicture.ImageLocation=URL;
}

check the folloing C# image load codes,
public static void LoadImageFromFileDemo()
{
string fileName = "c:/Sample.png";

REImage reImage = REFile.OpenImageFile(fileName);

}

i think it is easy for us to do image file loading, but from loading image from stream or frum graphics.much difficult.
most of us are simply using some software to do the job for us. but for programmer, we are searching for the most useful tool that can make things easier.
