Class ConvertBitmap

java.lang.Object

boofcv.android.ConvertBitmap

public class ConvertBitmap
extends java.lang.Object

Functions for converting Android Bitmap images into BoofCV formats. In earlier versions of Android there is no way to directly access the internal array used by Bitmap. You have to provide an array for it to be copied into. This is why the storage array is provided.

Method Detail

declareStorage

public static byte[] declareStorage(android.graphics.Bitmap input,
                                    byte[] storage)

Declares a storage array for the provided Bitmap image. The array will be of size = width*height*byteCount where byteCount is the number of bytes per pixel.

Parameters:

input - Bitmap image.

storage - If not null then the array size will be checked, if too small a new array will be returned.

Returns:

An array of appropriate size.

bitmapToBoof

public static <T extends boofcv.struct.image.ImageBase<T>> void bitmapToBoof(android.graphics.Bitmap input,
                                                                             T output,

Converts a Bitmap into a BoofCV image. Type is determined at runtime.

Parameters:

input - Bitmap image.

output - Output image. Automatically resized to match input shape.

storage - Byte array used for internal storage. If null it will be declared internally.

Converts Bitmap image into a single band image of arbitrary type.

Parameters:

input - Input Bitmap image.

output - Output single band image. If null a new one will be declared.

imageType - Type of single band image.

storage - Byte array used for internal storage. If null it will be declared internally.
