IWICBitmap interface (wincodec.h)
Defines methods that add the concept of writeability and static in-memory representations of bitmaps to IWICBitmapSource.
Inheritance
The IWICBitmap interface inherits from IWICBitmapSource. IWICBitmap also has these types of members:
Methods
The IWICBitmap interface has these methods.
IWICBitmap::Lock Provides access to a rectangular area of the bitmap. |
IWICBitmap::SetPalette Provides access for palette modifications. |
IWICBitmap::SetResolution Changes the physical resolution of the image. |
Remarks
IWICBitmap inherits from IWICBitmapSource and therefore also inherits the CopyPixels method. When pixels need to be moved to a new memory location, CopyPixels is often the most efficient.
Because of the internal memory representation implied by the IWICBitmap, in-place modification and processing using the Lock is more efficient than CopyPixels, usually reducing to a simple pointer access directly into the memory owned by the bitmap rather than a copy. This is contrasted to procedural bitmaps which implement only CopyPixels because there is no internal memory representation and one would need to be created on demand to satisfy a call to Lock.
