包路径：java.awt.image.BufferedImage
类名称：BufferedImage
方法名：setRGB

BufferedImage.setRGB介绍

[英]Sets a pixel in this BufferedImage to the specified RGB value. The pixel is assumed to be in the default RGB color model, TYPE_INT_ARGB, and default sRGB color space. For images with an IndexColorModel, the index with the nearest color is chosen.
[中]将此BufferedImage中的像素设置为指定的RGB值。假定该像素位于默认RGB颜色模型、类型_INT_ARGB和默认sRGB颜色空间中。对于具有IndexColorModel的图像，将选择具有最接近颜色的索引。
