Member Function Documentation

toBitmap()

static ScopedJObject Ocean::Platform::Android::Bitmap::toBitmap ( JNIEnv *  env, const Frame &  rgbaFrame  )

static

Converts a frame with pixel format FORMAT_RGBA32 to an Android bitmap.

Parameters

env	The JNI environment, must be valid
rgbaFrame	The frame to convert, with pixel format FORMAT_RGBA32, must be valid

Returns

The resulting Android bitmap, nullptr if the conversion failed

toFrame()

static Frame Ocean::Platform::Android::Bitmap::toFrame ( JNIEnv *  env, jobject  bitmap, const bool  copyData = true  )

static

Converts an Android bitmap to an Ocean frame.

The Android bitmap must have format ANDROID_BITMAP_FORMAT_RGBA_8888.

Parameters

env	The JNI environment, must be valid
bitmap	The Android bitmap to convert, must be valid
copyData	True, to copy the bitmap data; False, to use the bitmap data directly

Returns

The resulting Ocean frame, an invalid frame if the conversion failed

translateFormat() [1/2]

static FrameType::PixelFormat Ocean::Platform::Android::Bitmap::translateFormat ( const AndroidBitmapFormat  format )

static

Translates an Android bitmap format to an Ocean pixel format.

Parameters

format

The Android bitmap format to translate

Returns

The corresponding Ocean pixel format, FORMAT_UNDEFINED if unknown

translateFormat() [2/2]

static AndroidBitmapFormat Ocean::Platform::Android::Bitmap::translateFormat ( const FrameType::PixelFormat  pixelFormat )

static

Translates an Ocean pixel format to an Android bitmap format.

Parameters

pixelFormat

The Ocean pixel format to translate

Returns

The corresponding Android bitmap format, ANDROID_BITMAP_FORMAT_NONE if unknown
