Image.getFormat介绍

[英]Get the format for this image. This format determines the number of ByteBuffers needed to represent the image, and the general layout of the pixel data in each in ByteBuffer.

The format is one of the values from android.graphics.ImageFormat. The mapping between the formats and the planes is as follows:

FormatPlane countLayout detailsandroid.graphics.ImageFormat#JPEG1Compressed data, so row and pixel strides are 0. To uncompress, use android.graphics.BitmapFactory#decodeByteArray. android.graphics.ImageFormat#YUV_420_8883A luminance plane followed by the Cb and Cr chroma planes. The chroma planes have half the width and height of the luminance plane (4:2:0 subsampling). Each pixel sample in each plane has 8 bits. Each plane has its own row stride and pixel stride.android.graphics.ImageFormat#YUV_422_8883A luminance plane followed by the Cb and Cr chroma planes. The chroma planes have half the width and the full height of the luminance plane (4:2:2 subsampling). Each pixel sample in each plane has 8 bits. Each plane has its own row stride and pixel stride.android.graphics.ImageFormat#YUV_444_8883A luminance plane followed by the Cb and Cr chroma planes. The chroma planes have the same width and height as that of the luminance plane (4:4:4 subsampling). Each pixel sample in each plane has 8 bits. Each plane has its own row stride and pixel stride.android.graphics.ImageFormat#FLEX_RGB_8883A R (red) plane followed by the G (green) and B (blue) planes. All planes have the same widths and heights. Each pixel sample in each plane has 8 bits. Each plane has its own row stride and pixel stride.android.graphics.ImageFormat#FLEX_RGBA_88884A R (red) plane followed by the G (green), B (blue), and A (alpha) planes. All planes have the same widths and heights. Each pixel sample in each plane has 8 bits. Each plane has its own row stride and pixel stride.android.graphics.ImageFormat#RAW_SENSOR1A single plane of raw sensor image data, with 16 bits per color sample. The details of the layout need to be queried from the source of the raw sensor data, such as android.hardware.camera2.CameraDevice. android.graphics.ImageFormat#RAW_PRIVATE1A single plane of raw sensor image data of private layout. The details of the layout is implementation specific. Row stride and pixel stride are undefined for this format. Calling Plane#getRowStride()or Plane#getPixelStride() on RAW_PRIVATE image will cause UnSupportedOperationException being thrown.
