1、 摘要摘要 图片的合成和缩放我们实现了其基本的算法，本文通过 bmp 位图数据源，通过 采用双线形插值，后处理操作和合成算法实现了对图片的基本操作，并以此为基础实现 了对 bmp 位图的读写。试验结果表明，我们所实现的算法适用于对 BMP 位图文件的基本 操作。 在实现数字图象处理的过程中，主要是通过对图像中的每一个像素点运用各种图像 处理算法来达到预期的效果，所以进行图像处理的第一步，也是我们最关心的问题，是 如何得到图像中每一个像素点的亮度值；为了观察和验证处理的图像效果，另一个需要 解决的问题是如何将处理前后的图像正确的显示出来。我们就是解决这些问题。 关键词关键词：图片的合成和缩放；双

We solve these problems. Key words: Pictur
