是否可以在Delphi中平滑一个缩放的TBitmap？ [英] Is it possible to smooth a scaled TBitmap in Delphi?

问题描述

我在使用256x256位图的TImage上使用Stretched = True。这被缩小了1,2,4或8.如预期的那样，位图上的文字变得更加可怕，我离开'1'越多。
我注意到，虽然Windows 7资源管理器渲染了位图更软的缩小版本，更令人愉快。是否可以以这种方式模糊一个TBitmap？

I am using Stretched=True on a TImage with a 256x256 bitmap. This gets scaled down by 1,2,4 or 8. As expected, text on the bitmap gets more horrible the more I depart from '1'. I notice though that Windows 7 explorer renders a scaled down version of the bitmap 'softer' and more pleasing. Is it possible to 'blur' a TBitmap in this way?

推荐答案

我想你的意思是在TImage上Stretched = True在TBitmap上。

I suppose you mean Stretched = True on a TImage, not on A TBitmap.

不幸的是，TImage没有内置重新采样器，当涉及到调整其中的图像大小时。
我的建议是使用 Graphics32 ，因为它支持各种重新采样器（有些更适合增加大小其他减少大小）

Unfortunately TImage has no resamplers built in, when it comes to resizing images in it. My recommendation would be to use Graphics32 as it supports a variety of resamplers (some are better for increasing size others for reducing size)
