Introduction and Overview
The Pinboard has been updated to provide additional backdrop types and to allow applications to control the entire background window if necessary. The application now uses the ImageFileRender interfaces to render image files on the backdrop. This means that in addition to the Sprite and JPEG files which Pinboard has been able to render, it can also render any format which is supported by the ImageFileRender stack. In particular, this means that DrawFiles and PNGs may be used. The rendering of these images may be subject to delays in conversion for some image formats.
