Importing stream into editor

[Christie Admin]

Hi,

 I'm using the latest version of Telerik and I created a UserControl which contain a RadImageEditorUI. My UserControl contain a property named "Image" of type "Stream" and I would like to know how I can display it in the editor and I would like to know also how I can take the image in the editor and transform it as a stream?

 

Thank's

Alain

Hi Alain,

In order to display an image in the control, you could import the stream into the RadImageEditor using the appropriate format provider. More information about how to achieve this you can find in the Import/Export article. The image from the control could be exported directly to a file or to a byte[] using the different overloads of the Export() method of the corresponding format provider.

I hope this helps.

Ho Tanya,

 

actually, our application save/load an image into our database as a stream so can you provide me an example on how I can assign a stream to the editor and convert the editor image to a stream?!?

 

Thank's

Hi Alain,

As Tanya suggested, you could use the RadImageEditor's format providers in order to import/export images. If you have exported the image to byte[], you could check this article on StackOverflow about converting byte array to a stream. In addition, you could use the format provider's overload of the Export() method which gets as a parameter a stream object in which the image shall be written.

For your convenience, I've created a sample demo project which uses the second mentioned approach. You can find it attached.

I hope this helps.
