WPF ImageScalingMode最近邻居
[英]WPF ImageScalingMode NearestNeighbor
问题描述
We are porting C++ image scaling algorithm, which scales the image in the following way. 
我们正在移植C ++图像缩放算法，该算法以以下方式缩放图像。 We have used NearestNeighbor ImageScalingMode to replicate the behavior in WPF. 我们使用NearestNeighbor ImageScalingMode复制WPF中的行为。 The image scaling works fine in WPF with scaling up. 图像缩放在WPF中可以按比例放大。 But it does not work with scaling down. 但这不适用于缩小规模。 Did I select the wrong scaling mode in WPF? 我在WPF中选择了错误的缩放模式吗？ or should I do anything else to obtain the desired behavior? 还是我应该做其他事情以获得所需的行为？
