getType

@NonNull
public static ImageHeaderParser.ImageType getType(@NonNull
 List<ImageHeaderParser> parsers,
 @Nullable
 InputStream is,
 @NonNull
 ArrayPool byteArrayPool)
                                           throws IOException

Returns the ImageType for the given InputStream.

Throws:

IOException

getType

@NonNull
public static ImageHeaderParser.ImageType getType(@NonNull
 List<ImageHeaderParser> parsers,
 @Nullable
 ByteBuffer buffer)
                                           throws IOException

Returns the ImageType for the given ByteBuffer.

Throws:

IOException

getType

@NonNull
@RequiresApi(21)
public static ImageHeaderParser.ImageType getType(@NonNull
 List<ImageHeaderParser> parsers,
 @NonNull
 ParcelFileDescriptorRewinder parcelFileDescriptorRewinder,
 @NonNull
 ArrayPool byteArrayPool)
                                           throws IOException

Throws:

IOException

getOrientation

public static int getOrientation(@NonNull
 List<ImageHeaderParser> parsers,
 @Nullable
 ByteBuffer buffer,
 @NonNull
 ArrayPool arrayPool)
                          throws IOException

Returns the result from the first of parsers that returns something other than ImageHeaderParser.UNKNOWN_ORIENTATION.

If buffer is null, the parers list is empty, or none of the parsers returns a valid value, ImageHeaderParser.UNKNOWN_ORIENTATION is returned.

Throws:

IOException

getOrientation

 List<ImageHeaderParser> parsers,
 @Nullable
 InputStream is,
 @NonNull
 ArrayPool byteArrayPool)
                          throws IOException

Returns the orientation for the given InputStream.

Throws:

IOException
