Description

How to save an image without cropping it while the CropTool is active.

Solution

1. Create a custom SaveImage command and override its ExecuteOverride method. If the executing tool is CropTool avoid commiting the tool, thus cropping the picture.

   C#

   	public class CustomSaveImageCommand : SaveImageCommand
   	{
   		public CustomSaveImageCommand(RadImageEditor owner) : base(owner)
   		{
   		}
   
   		protected override void ExecuteOverride(object parameter)
   		{
   			SaveFileDialog dialog = new SaveFileDialog();
   
   			string stringParameter = parameter as string;
   			if (stringParameter != null && stringParameter.Contains("|"))
   			{
   				dialog.Filter = stringParameter;
   			}
   			else
   			{
   				dialog.Filter = FormatProviderToFilterConverter.GetFilter(ImageFormatProviderManager.RegisteredFormatProviders, false, false, stringParameter);
   			}
   
   			bool? dialogResult = dialog.ShowDialog();
   			if (dialogResult == true)
   			{
   				if (!(this.Owner.ExecutingTool is CropTool))
   				{
   					this.Owner.CommitTool();
   				}                
   
   				string extension = System.IO.Path.GetExtension(dialog.SafeFileName);
   				IImageFormatProvider formatProvider = ImageFormatProviderManager.GetFormatProviderByExtension(extension);
   				using (Stream output = dialog.OpenFile())
   				{
   					formatProvider.Export(this.Owner.Image, output);
   				}
   			}
   		}
   	}
   	
   	public static class FormatProviderToFilterConverter
   	{
   		public static string GetFilter(IEnumerable<IImageFormatProvider> formatProviders, bool isImport, bool addAllFiles, string filter)
   		{
   			if (!string.IsNullOrEmpty(filter))
   			{
   				string[] extensions = filter.Split(',', ';').Select(e => e.Trim('.').ToLower()).ToArray();
   				formatProviders = formatProviders.Where(fp => fp.SupportedExtensions.Any(ext => extensions.Contains(ext.Trim('.').ToLower())));
   			}
   
   			if (isImport)
   			{
   				formatProviders = formatProviders.Where(fp => fp.CanImport);
   			}
   			else
   			{
   				formatProviders = formatProviders.Where(fp => fp.CanExport);
   			}
   
   			return
   				string.Join("|", formatProviders.Select(fp => GetFilter(fp)).ToArray()) +
   				(addAllFiles ? "|All Files|*.*" : "");
   		}
   
   		public static string GetFilter(IImageFormatProvider formatProvider)
   		{
   			return
   				formatProvider.FilesDescription +
   				" (" +
   				string.Join(", ", formatProvider.SupportedExtensions.Select(ext => "*" + ext).ToArray()) +
   				")|" +
   				string.Join(";", formatProvider.SupportedExtensions.Select(ext => "*" + ext).ToArray());
   		}
   	}

2. Set the custom command to the RadImageEditorUI via its SaveCommand property.

   C#

   	this.radImageEditorUI.SaveCommand = new CustomSaveImageCommand(this.ImageEditorUI.ImageEditor);
