This unit contains a improved bitmap, which may load data from different picture sources and gives the possibility of easy pixel access.
| Name | Description |
|---|---|
Class ENoValidCompressor |
This exception is raised when no proper compressor is found to load the bitmap data from a stream or a file |
Class ENoValidFormat |
This exception is raised when no format loader is found to load the bitmap data from the specified data source. |
Class TAdGraphicCompressor |
TAdGraphicCompressor is an abstract class, which allows to save bitmap data using different encoding and compressing technologies. |
Class TAdGraphicFormat |
The abstract TAdGraphicFormat class should be used to load various graphic classes into a TAdBitmap. |
Class TAdBitmap |
