示例1: GetTargetSize
private static Size GetTargetSize(this ImageResizeRequestModel request, Size originalSize)
{
var maxWidth = request.GetMaxWidth(originalSize);
var maxHeight = request.GetMaxHeight(originalSize);
var aspectRatio = originalSize.GetAspectRatio();
Size targetSize;
// if image is taller than it is wide, aspect ratio will be less than 1
// in these cases, adjust the width based on the height
// also take this approach when the image is perfectly square (aspect ratio == 1.0)
if (aspectRatio <= 1)
{
targetSize = originalSize.ReduceByHeight(maxHeight);
// width can still be greater than maxWidth
if (targetSize.Width > maxWidth)
// now we have to reduce the height based on the max width
targetSize = originalSize.ReduceByWidth(maxWidth);
}
// if image is wider than it is tall, aspect ratio will be greater than 1
// in these cases, adjust the height based on the width
else
{
targetSize = originalSize.ReduceByWidth(maxWidth);
// height can still be greater than maxHeight
if (targetSize.Height > maxHeight)
// now we have to reduce the width based on the max height
targetSize = originalSize.ReduceByHeight(maxHeight);
}
return targetSize;
