利用Java制作字符动画实例代码

BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file)));
		int width = bi.getWidth();//原图宽度
		int height = bi.getHeight();//原图高度
		int minx = bi.getMinX();//BufferedImage 原图 最小X坐标
		int miny = bi.getMinY(); //BufferedImage 原图 最小Y坐标
		for (int i = miny; i < height; i += 8) {//遍历图片中的像素点，用字符判断像素范围来替换
			for (int j = minx; j < width; j += 8) {
				int pixel = bi.getRGB(j, i); // 下面三行代码将一个数字转换为RGB数字
				int red = (pixel & 0xff0000) >> 16;
				int green = (pixel & 0xff00) >> 8;
				int blue = (pixel & 0xff);
				double gray = 0.299 * red + 0.578 * green + 0.114 * blue; //图片变灰计算公式
				char c = toChar((int) gray); //根据计算出来的gray值返回不同字符
				bufferedWriter.write(c);
			}
			bufferedWriter.newLine();
		}
		//输出图片

// initialize caches
AsciiImgCache smallFontCache = AsciiImgCache.create(new Font("Courier",Font.BOLD, 6));
// initialize ssimStrategy
BestCharacterFitStrategy ssimStrategy = new StructuralSimilarityFitStrategy();

String srcFilePath = "examples/xxx.gif";
String disFilePath = "examples/xxx.gif";
int delay = 100;//ms

GifToAsciiConvert asciiConvert = new GifToAsciiConvert(smallFontCache, ssimStrategy);

asciiConvert.convertGitToAscii(srcFilePath, disFilePath, delay,0);
