  • decodeFile

    public static Bitmap decodeFile(String pathName,
                    BitmapFactory.Options opts)

    Decode a file path into a bitmap. If the specified file name is null, or cannot be decoded into a bitmap, the function returns null.

    Parameters:

    pathName - complete path name for the file to be decoded.

    opts - null-ok; Options that control downsampling and whether the image should be completely decoded, or just is size returned.

    Returns:

    The decoded bitmap, or null if the image data could not be decoded, or, if opts is non-null, if opts requested only the size be returned (in opts.outWidth and opts.outHeight)

  • decodeFile

    public static Bitmap decodeFile(String pathName)

    Decode a file path into a bitmap. If the specified file name is null, or cannot be decoded into a bitmap, the function returns null.

    Parameters:

    pathName - complete path name for the file to be decoded.

    Returns:

    the resulting decoded bitmap, or null if it could not be decoded.

  • decodeResourceStream

    public static Bitmap decodeResourceStream(Resources res,
                              TypedValue value,
                              InputStream is,
                              Rect pad,
                              BitmapFactory.Options opts)

    Decode a new Bitmap from an InputStream. This InputStream was obtained from resources, which we pass to be able to scale the bitmap accordingly.

  • decodeResource

    public static Bitmap decodeResource(Resources res,
                        int id,
                        BitmapFactory.Options opts)

    Synonym for opening the given resource and calling decodeResourceStream(android.content.res.Resources, android.util.TypedValue, java.io.InputStream, android.graphics.Rect, android.graphics.BitmapFactory.Options).

    Parameters:

    res - The resources object containing the image data

    id - The resource id of the image data

    opts - null-ok; Options that control downsampling and whether the image should be completely decoded, or just is size returned.

    Returns:

    The decoded bitmap, or null if the image data could not be decoded, or, if opts is non-null, if opts requested only the size be returned (in opts.outWidth and opts.outHeight)

  • decodeResource

    public static Bitmap decodeResource(Resources res,
                        int id)

    Synonym for decodeResource(Resources, int, android.graphics.BitmapFactory.Options) will null Options.

    Parameters:

    res - The resources object containing the image data

    id - The resource id of the image data

    Returns:

    The decoded bitmap, or null if the image could not be decode.

  • decodeByteArray

    public static Bitmap decodeByteArray(byte[] data,
                         int offset,
                         int length,
                         BitmapFactory.Options opts)

    Decode an immutable bitmap from the specified byte array.

    Parameters:

    data - byte array of compressed image data

    offset - offset into imageData for where the decoder should begin parsing.

    length - the number of bytes, beginning at offset, to parse

    opts - null-ok; Options that control downsampling and whether the image should be completely decoded, or just is size returned.

    Returns:

    The decoded bitmap, or null if the image data could not be decoded, or, if opts is non-null, if opts requested only the size be returned (in opts.outWidth and opts.outHeight)

  • decodeByteArray

    public static Bitmap decodeByteArray(byte[] data,
                         int offset,
                         int length)

    Decode an immutable bitmap from the specified byte array.

    Parameters:

    data - byte array of compressed image data

    offset - offset into imageData for where the decoder should begin parsing.

    length - the number of bytes, beginning at offset, to parse

    Returns:

    The decoded bitmap, or null if the image could not be decode.

  • decodeStream

    public static Bitmap decodeStream(InputStream is,
                      Rect outPadding,
                      BitmapFactory.Options opts)

    Decode an input stream into a bitmap. If the input stream is null, or cannot be used to decode a bitmap, the function returns null. The stream's position will be where ever it was after the encoded data was read.

    Parameters:

    is - The input stream that holds the raw data to be decoded into a bitmap.

    outPadding - If not null, return the padding rect for the bitmap if it exists, otherwise set padding to [-1,-1,-1,-1]. If no bitmap is returned (null) then padding is unchanged.

    opts - null-ok; Options that control downsampling and whether the image should be completely decoded, or just is size returned.

    Returns:

    The decoded bitmap, or null if the image data could not be decoded, or, if opts is non-null, if opts requested only the size be returned (in opts.outWidth and opts.outHeight)

  • decodeStream

    public static Bitmap decodeStream(InputStream is)

    Decode an input stream into a bitmap. If the input stream is null, or cannot be used to decode a bitmap, the function returns null. The stream's position will be where ever it was after the encoded data was read.

    Parameters:

    is - The input stream that holds the raw data to be decoded into a bitmap.

    Returns:

    The decoded bitmap, or null if the image data could not be decoded.

  • decodeFileDescriptor

    public static Bitmap decodeFileDescriptor(FileDescriptor fd,
                              Rect outPadding,
                              BitmapFactory.Options opts)

    Decode a bitmap from the file descriptor. If the bitmap cannot be decoded return null. The position within the descriptor will not be changed when this returns, so the descriptor can be used again as-is.

    Parameters:

    fd - The file descriptor containing the bitmap data to decode

    outPadding - If not null, return the padding rect for the bitmap if it exists, otherwise set padding to [-1,-1,-1,-1]. If no bitmap is returned (null) then padding is unchanged.

    opts - null-ok; Options that control downsampling and whether the image should be completely decoded, or just is size returned.

    Returns:

    the decoded bitmap, or null

  • decodeFileDescriptor

    public static Bitmap decodeFileDescriptor(FileDescriptor fd)

    Decode a bitmap from the file descriptor. If the bitmap cannot be decoded return null. The position within the descriptor will not be changed when this returns, so the descriptor can be used again as is.

    Parameters:

    fd - The file descriptor containing the bitmap data to decode

    Returns:

    the decoded bitmap, or null
