Export image in ImageEditor in code behind ?

[Olivier Constance]

Hi,

I use the WPF Q1 2012 SP1.

I just want to export/save the image contained in the ImageEditor with my own method.

What is the better way to do that ?

Thanks for your help.

Hi Olivier,

You can use the available format providers to encode the images in a specific format – e.g. BMP or PNG - in the same way as illustrated in the AddImageInEditor method in the documentation. Here is an example:

   private void ExportImageInEditor()

      {

          SaveFileDialog sfd = new SaveFileDialog();

          sfd.Filter = "PNG Images (*.png)|*.png|BMP Images (*.bmp)|*.bmp;*|All images|*.*";

          sfd.FilterIndex = 3;

          if (sfd.ShowDialog() == true)

          {

              string extension = System.IO.Path.GetExtension(sfd.SafeFileName).ToLower();

              Stream stream = sfd.OpenFile();

              IImageFormatProvider formatProvider = ImageFormatProviderManager.GetFormatProviderByExtension(extension);

              if (formatProvider == null)

              {

                  StringBuilder sb = new StringBuilder();

                  sb.Append("Unable to find format provider for extension: ")

                    .Append(extension).Append(" .");

                  return;

              }

              else

              {

                  using (stream)

                  {

                  formatProvider.Export(this.imageEditorUI.Image, stream);

                  }

              }

          }
     }

Note that if you have some uncommitted change in the image and you want it to be present in the exported file, you should commit it programmatically:

this.imageEditorUI.ImageEditor.CommitTool();
