Reporting - Picture Box Enhancements (v18.2)

For v18.2 we are delivering some great features to support freehand drawing and image uploads in the Print Preview - for signatures and other purposes - as well as the SVG image format. All platforms supported by our Reporting system benefit from these updates.

All new functionality is supported by the XRPictureBox report control. Its EditOptions property is populated with an instance of the new type ImageEditOptions, and this is where you find the property EditorName that is explained in more detail below.

Freehand Drawing in the Print Preview

To allow users to draw directly into a report in the Print Preview, set the property ImageEditOptions.EditorName to Signature. When the editor is activated, the user can choose colors and brush sizes in the flyout panel:

Image Upload in the Print Preview

Image uploads are allowed when ImageEditOptions.EditorName is set to Image. You can then choose sizing mode and image alignment in the flyout panel at runtime (these correspond to the design-time properties Sizing and ImageAlignment).

The Picture Box allows image uploads and freehand drawing simultaneously when ImageEditOptions.EditorName is set to ImageAndSignature.

All image editors include a Remove button. This button resets the editor value to the image provided in the InitialImage property.

Predefined Image Lists

The final new editor type is the image list. Helper methods are available to register image editors with collections of predefined images. For instance, this code registers an editor for national flags in a WinForms application:

var images = new List<Image>();

foreach (var file in Directory.GetFiles("../../Flags/", "*.png")) {
  var img = Image.FromFile(file);
  if (img != null)
    images.Add(img);
}

EditingFieldExtensionsWin.Instance.RegisterImageCollectionEditorInfo(
  "Nationality", "Nationality", images);

With the registration in place, set ImageEditOptions.EditorName to the name of the editor (Nationality in this example). When an end user clicks the Picture Box in the Print Preview, they can choose a predefined image from the list:

SVG Image Support

Using the new property XRPictureBox.ImageSource, the control now supports SVG format images. The implementation currently doesn’t support images with gradients or text elements. We hope to extend the feature set in future versions. Please let us know your priorities.

SVG images are preserved when a report is exported to a PDF file. Other export formats include a metafile or a bitmap.
