PNG (Portable Network Graphics) is a replacement for the GIF format. It is a full-featured (non-LZW) compressed format intended for widespread use without legal restraints.
LEADTOOLS supports reading (but not writing) interlaced PNG files. To implement the paint-while-load feature, set the Passes property to paint the image in more than one pass.
The file constants associated with this file format are:
| Constant | Read Support | Write Support | Description |
| Png | 1, 4, 8, 16, 24, 32 BPP | 1, 4, 8, 24, 32 BPP | Portable Network Graphics (PNG). |
Required DLL: Leadtools.Codecs.Png.Dll. For a listing of the exact DLLs needed, based on the toolkit version, refer to Files To Be Included With Your Application.
