在Android中,将ByteArray转换为Bitmap是一个常见的操作,通常用于处理图像数据。以下是详细的步骤说明,包括必要的代码片段: 准备ByteArray: 假设你已经有一个包含图像数据的ByteArray。 java byte[] byteArray = ...; // 你的字节数组 使用BitmapFactory解码ByteArray: BitmapFactory.decodeByteArray() 方法可以直接...
Bitmap -> byte[] 创建一个ByteBuffer用于接收数据。首先需要爲buffer开辟内存空间,内存空间的大小就是图片的大小。将bitmap的数据写入buffer,然后调用buffer的array()方法得到array. intbytes=bmp.getByteCount();ByteBufferbuf=ByteBuffer.allocate(bytes); bmp.copyPixelsToBuffer(buf);byte[] byteArray = buf.array()...

BitmapData 转换为 ByteArray获得BitmapData对应的字节数组, 所要做的只是调用getPixels()方法。 getPixels()方法需要指定捕捉区域;最便捷的方法就是使用即将序列化的BitmapData的rect属性。 // ActionScript. 3.0 // 假定“bitmapImage”是需要序列化的位图对象 var bytes:ByteArray = bitmapImage.bitmapData.getPi...
Android Bitmap 和 ByteArray的互相转换 移动平台图像处理,需要将图像传给native处理,如何传递?将bitmap转换成一个 byte[] 方便传递也方便cpp代码直接处理图像内容。 Bitmap -> byte[] 创建一个ByteBuffer用于接收数据。首先需要爲buffer开辟内存空间,内存空间的大小就是图片的大小。将bitmap的数据写入...

c om public class Main{ public static Bitmap CreateBitmap(byte[,] image) { int xsize = image.GetLength(0); int ysize = image.GetLength(1); Bitmap b = new Bitmap( xsize , ysize ); //b.PixelFormat = PixelFormat.Format8bppIndexed; for (int x = 0; x < xsize; x++) { for...
或者使用ToByteArray方法将图像转换为byte[]数组: 代码语言:csharp 复制 byte[] outputData = image.ToByteArray(); 推荐的腾讯云相关产品和产品介绍链接地址: 腾讯云对象存储(COS):提供高可靠、低成本的云端存储服务,适用于存储和管理各种类型的数据。产品介绍链接:https://cloud.tencent.com/product/cos 腾讯云云...
