PocketBuilder 2.5.1 supports the Portable Networks Graphics (PNG) file format for the images that you use in menus, toolbars, treeview controls, and DataWindow objects. PNG images display at design time as they do at runtime.
PNG images are supported on handheld devices running Windows Mobile 2003 Second Edition or later. PNG images in DataWindow objects are not supported and cannot be selected in DataWindow objects with the RichText or OLE presentation style.
PNG images are drawn with GDI+ functions rather than with bitmap functions. Therefore the Map3DColors property for Picture and PictureButton controls is ignored when you select a PNG file for the picture image. PNG images are also kept locked while the image is active, in contrast to bitmap images which are released once the image is loaded.
