Method Detail

yuvRotateToUpright

@Deprecated
public static YuvBuffer yuvRotateToUpright(@NonNull
                                                       YuvBuffer input)

Deprecated.

Rotate YUV image by its preset rotation value to restore upright image. Will return input if rotation is 0. Result rotation will always be 0.

yuvRotateToUpright

@Deprecated
public static boolean yuvRotateToUpright(@NonNull
                                                     YuvBuffer input,
                                                     @NonNull
                                                     YuvBuffer output)

Deprecated.

Rotate YUV image by its preset rotation value to restore upright image. Result will be written to output, which will always have rotation 0.

yuvRotate

@Deprecated
public static YuvBuffer yuvRotate(@NonNull
                                              YuvBuffer input,
                                              int degrees)

Deprecated.

Rotate YUV image to new buffer if required. If no rotation is required, the original buffer is returned.

yuvRotate

@Deprecated
public static boolean yuvRotate(@NonNull
                                            YuvBuffer input,
                                            @NonNull
                                            YuvBuffer output,
                                            int degrees)

Deprecated.

Rotate YUV image to preallocated buffer. Allows finer control of memory than yuvRotate(YuvBuffer, int), so applications can reuse buffers rather than allocating each time. If the provided buffer is not large enough, this will reallocate the data block, but otherwise no allocations will be made.

Returns:

True if the operation succeeded

yuvRotate

public static void yuvRotate(@NonNull
                             com.yoti.mobile.android.commons.image.ImageBuffer input,
                             @NonNull
                             byte[] output,
                             int degrees)
                      throws YuvException

Raw rotation method for buffer data. Suitable for use in fillData method, consumer must adjust width/ height correctly to ensure the image displays as expected. External consumers shouldn't use this directly, as the same functionality is provided by RotationBuffer.

Throws:

YuvException

yuvCrop

@Deprecated
public static YuvBuffer yuvCrop(YuvBuffer input,
                                            android.graphics.RectF cropRectangle)

Deprecated.

NB. Output size is not guaranteed to match rect size. Always use the outputted width and height.

yuvCrop

public static com.yoti.mobile.android.commons.image.DirectBuffer yuvCrop(com.yoti.mobile.android.commons.image.ImageBuffer inputBuffer,
                                                                         android.graphics.RectF cropRectangle)

convertYuvToRgb

@Deprecated
public static java.nio.ByteBuffer convertYuvToRgb(@NonNull
                                                              YuvBuffer input,
                                                              @Nullable
                                                              java.nio.ByteBuffer recycleBuffer)

Deprecated.

Convert YuvBuffer data to direct mapped RGB data. Output will be 24bpp packed RGB data, stride = width*3.

Parameters:

input - YUV data to convert

recycleBuffer - Previous return value to reuse, or null for the first call

Returns:

RGB data buffer, or null if conversion fails. This should be kept by the caller to reuse on future calls to avoid repeated big allocations.

convertYuvBufferToBitmap

@Deprecated
public static android.graphics.Bitmap convertYuvBufferToBitmap(YuvBuffer yuvImage)

Deprecated.

convertYuvBufferToBitmap

@Deprecated
public static android.graphics.Bitmap convertYuvBufferToBitmap(android.content.Context context,
                                                                           YuvBuffer yuvImage)

Deprecated.

generateYUVFormat

public static com.yoti.mobile.android.core.yuvtools.YuvModel generateYUVFormat(@NonNull
                                                                               byte[] bytes,
                                                                               int width,
                                                                               int height,

Read a YUV saved picture and create a YotiYUV object where Y is width * height and UV is 0.5 * width * height. Both Y and UV must be GZip compressed.

Parameters:

bytes - - the YUV bytes

width - - the picture width

height - - the picture height

noModify - true if the input bytes will be used after this call, so must not be modified. Will be faster if false

Returns:

a YotiYUV object

generateYUVFormat
