IWICBitmapFlipRotator interface (wincodec.h)
Exposes methods that produce a flipped (horizontal or vertical) and/or rotated (by 90 degree increments) bitmap source. The flip is done before the rotation.
Inheritance
The IWICBitmapFlipRotator interface inherits from IWICBitmapSource. IWICBitmapFlipRotator also has these types of members:
Methods
The IWICBitmapFlipRotator interface has these methods.
| IWICBitmapFlipRotator::Initialize Initializes the bitmap flip rotator with the provided parameters. |
Remarks
IWICBitmapFipRotator requests data on a per-pixel basis, while WIC codecs provide data on a per-scanline basis. This causes the fliprotator object to exhibit n² behavior if there is no buffering. This occurs because each pixel in the transformed image requires an entire scanline to be decoded in the file. It is recommended that you buffer the image using IWICBitmap, or flip/rotate the image using Direct2D.
