RadBarCode GetImage throws GDI+ error on server

When we use the RadBarcode.GetImage() running the asp.net 4.0 site inside the visual studio 2012 IDE all is well and we can save and display the png on our site. When running the site on the server we get the following error:

A generic error occurred in GDI+.    at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams)
   at System.Drawing.Image.Save(String filename, ImageFormat format)

No other error information is provided. Are there perhaps some other support assemblies needed that may be needed on the server?    This telerik upgrade is being tested on 2003 server, where all other telerik stuff works just fine for a number of sites. Is it possible the older server just doesn't support some GDI+ functionality that you require, and our only option is to move to server 2008?

We are in the process of switching our sites from rather ancient Windows Server 2003 to Windows Server 2008 so that's not a show-stopper. We just weren't quite ready to deploy this testing site there.

Barcode as Image

Love the new barcode control. QR is great.

I'm trying to setup a generic barcode generator that can be used through out my app (http://whatever/barcode.aspx?value=xyz) and have it generate a PNG image. I know in the Q2 release this was not possible since PNG was not supported. However now that it is, I would love a few suggestions on how I could render the barcode image in code-behind (C#) and then just stream it out to the browser.

Basically I just need to be able to get to the PNG image for the barcode from the control.

Thanks,
Alex

How to purge padding space between the image border and QRCode symbol?

Dear All,

I have the following code to generate QR Code dynamically:

public Image GetQRCode(string sUrl, int iDotSize)

{

var code = new RadBarcode();

code.Text = sUrl;

code.Type = BarcodeType.QRCode;

code.OutputType = BarcodeOutputType.EmbeddedPNG;

code.QRCodeSettings.Mode = Telerik.Web.UI.Barcode.Modes.CodeMode.Byte;

code.QRCodeSettings.ErrorCorrectionLevel = Telerik.Web.UI.Barcode.Modes.ErrorCorrectionLevel.L;

code.QRCodeSettings.DotSize = iDotSize;

code.QRCodeSettings.Version = 2;

code.QRCodeSettings.ECI = Telerik.Web.UI.Barcode.Modes.ECIMode.None;

//code.QRCodeSettings.DotSize = 0; // no changes, space is always there

//code.Attributes.Add("Width", "310px"); // no changes, space is always there

//code.Attributes.Add("Height", "310px"); // no changes, space is always there

return code.GetImage();

}

Can any one tell me how to purge padding space between the image border and QRCode symbol?
According to the documentation changing DotSize to zero should resize the QR symbol to fill up the Width and Height.
It doesn't work, the white space is always there. I tried also several other setting without success.
Greatly appreciate for any helps.

Regards,
Christopher
