Turn your photos into a Pivot collection

image

Microsoft Pivot (a cool new technology that lets you easily view, search, and filter data using deep zoom) seemed like a natural and obvious fit for the task.

Therefore, using Microsoft Pivot and the Pauthor open source libraries, I created  a tool that helps users create a pivot collection from the photos on their hard drive and supports filtering by all the nifty meta data embedded in those files such as shutter speed, aperture, film speed, and focal length. Plus, users end up with a great look set of deep zoom images from their photo collection!

PAuthor: The Pivot Collection Tool (a.k.a. Pauthor) is a command line tool for converting Pivot collections between a variety of formats (CSV, Excel, CXML with raw images, and CXML with DeepZoom images) and for creating imagery for those collections. This tool is ideal for a wide variety of cases from quickly converting any spreadsheet into a Pivot collection to serious collection authors creating collections as part of an automated workflow. With a built-in image creation system based upon HTML and CSS, you’ll find it very easy to augment your existing images, or generate entirely new images from scratch.

Adding Drag and Drop Support using DragDropTarget in Silverlight Toolkit

A DragDropTarget is a Content Control that adds default drag and drop actions to the control nested inside of it.  DragDropTarget’s provide the following functionality:

1.  Initiates a drag operation when an item container is dragged.

2.  Displays a snapshot of the the item container by the mouse while it is being dragged.

3.  Handles drag target events and specifies which drag operations are possible by examining the item source bound to the nested control.

4.  If an item is dropped onto the drag drop target, it is added to the nested control if the nested control is bound to an ObservableCollection (or any collection that implements INotifyCollectionChanged and contains the same type of items as the item that was dropped).

5.  Where possible, scrolls vertically and horizontally when an item is dragged near the edge of the control.

This release of the toolkit introduces the following implementations:

  • ListBoxDragDropTarget
  • TreeViewDragDropTarget
  • DataGridDragDropTarget
  • DataPointSeriesDragDropTarget
