BitmapScalingMode Enumeration
Specifies which algorithm is used to scale bitmap images.
Assembly: PresentationCore (in PresentationCore.dll)
| Member name | Description | |
|---|---|---|
| Unspecified | Use the default bitmap scaling mode, which is Linear. | |
| LowQuality | Use bilinear bitmap scaling, which is faster than HighQuality mode, but produces lower quality output. The LowQuality mode is the same as the Linear mode. | |
| HighQuality | Use high quality bitmap scaling, which is slower than LowQuality mode, but produces higher quality output. The HighQuality mode is the same as the Fant mode. | |
| Linear | Use linear bitmap scaling, which is faster than HighQuality mode, but produces lower quality output. | |
| Fant | Use very high quality Fant bitmap scaling, which is slower than all other bitmap scaling modes, but produces higher quality output. | |
| NearestNeighbor | Use nearest-neighbor bitmap scaling, which provides performance benefits over LowQuality mode when the software rasterizer is used. This mode is often used to magnify a bitmap. |
When animating the scale of any bitmap, the default high-quality image re-sampling algorithm can sometimes consume sufficient system resources to cause frame rate degradation. This frame rate degradation can cause animations to skip frames or stutter. By setting the BitmapScalingMode property of the RenderOptions object to LowQuality you can create a smoother animation when scaling a bitmap.
