IWICBitmapFlipRotator interface

Exposes methods that produce a flipped (horizontal or vertical) and/or rotated (by 90 degree increments) bitmap source. Rotations are done before the flip.

Members

The IWICBitmapFlipRotator interface inherits from IWICBitmapSource. IWICBitmapFlipRotator also has these types of members:

Methods

The IWICBitmapFlipRotator interface has these methods.

MethodDescription
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 occures 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.
