The issues reproduces, if you load an image, using System.Drawing.Image.Image and then create a stream using its Save() method. Then use this stream to create a RadBitmap element. In order to recreate the issue, the ImageFormat.Jpeg should be used with the Image's Save() method.

When you call one of the rotate commands in order to rotate the image, the image goes blank.

The issue is not directly related to the implementation of the ImageEditor control, but to the Rotate method of RadBitmap which is used by the ImageEditor.

To work this around, use ImageFormat.Png instead of Jpeg when saving the image to a stream (from the System.Drawing.Image object).
       

The setting should be available in the settings UI, the DrawTextCommandContext and it should be respected in the DrawText command's Execute method.

Scheduled for: 
The feature will be available in R1 2019, scheduled for the mid of January 2019. 

In Shape and DrawText tools there are strings which are not changed if the current culture is changed during the lifetime of an application.

The feature will be available in our official release 2015 Q2 .

Add an option to zoom towards the mouse cursor.

Some formats that can be considered are JPEG 2000, CALS, GIF, IOCA, JBIG, JBIG2, TGA, TIFF, EXIF, ICO.

Add tool for creating selection, and integrate the other tools to work only in the selected region, if one is present.

If you have a large image inside RadImageEditor or have zoomed a relatively big image, it would be great to have the ability to set panning on, so that the user can move around more easily.


Available in R1 2017 Release
