Barcode as Image

[Alex Smith]

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

Hello Alex,

Currently it is not possible, but the functionality that you describe is scheduled for the next release. It will be possible in Q1 2013 to access the image as "System.Drawing.Image" and to save it on your server.

In addition to saving it on disk will it be able to save to a stream?

[Vasil]

Hi Neil,

Yes, once you have the rendered image as System.Drawing.Image you will be able to use it as you want, including passing it into stream.

hi, Alex
have you found any good solutions?

Hello Arron,

I have removed the links from your post, since we do not encourage advertising other products in our forums.
Saving into stream is already possible from our last release, check this help topic for an working example:

Well, the barcode image generator is great, and I wonder do you know some barcoding SDK that can generate barcode in a picture?

[Vasil]

Hi Shawn,

If you want to save the generated Barcode in some image format you can use the Save method of the Image class, once you use the OutputType="EmbeddedPNG" as shown in the help topic that I have posted earlier. Check this article about saving an Image:

Hello Helouize,

Do you mean PDF417? To scan such barcode, you need to pass it in the formats option of the scanner as explained here (the link also contains a list of supported barcode types). This option is not added in the Barcode Scanner Sample and you should add it manually.
