java中如何画位图?

[qq_pride]

有一个2维数组，里面存放的是像素信息，不知道java中有没有类可以根据2维数组创建位图？

[qq_pride]

java好像不支持bmp吧

javax.imageio 中有圖片io操作類
嘗試下是否能把你的數據作爲數據流傳進某個操作類中

ImageIcon

public ImageIcon(byte[] imageData)

Creates an ImageIcon from an array of bytes which were read from an image file containing a supported image format, such as GIF or JPEG. Normally this array is created by reading an image using Class.getResourceAsStream(), but the byte array may also be statically stored in a class. If the resulting image has a "comment" property that is a string, then the string is used as the description of this icon.

可以的 我正在弄这方面的问题 你可以通过文件读取 把数据读入内存图形源中 MemoryImageSource 然后把设置 rgb值 就上你数组中的像素值。然后
Memoryimagesource = new MemoryImageSource(width，height，model，pix，0，width);
image=createImage(memoryimagesource);
把图象显示出来
最后把参考如何保存为位图文件的方式
即 你要了解位图文件的头文件格式和信息
BMPFileHeader和BMPInfoHeader
最后
BMPCodec.createBMPEncoder(new FileOutputStream("C:\\house\\test.bmp")).encode(image);
就可以了
