Constructor Detail

AsyncDecodeFileForced

public AsyncDecodeFileForced(java.lang.String path,
                             int inSampleSize,
                             OnBitmapRendered onBitmapRendered,
                             OnBitmapRenderFailed onBitmapRenderFailed,
                             EpicBitmapCache epicBitmapCache)

All parameters constructor.

Parameters:

path - Physical path of File in the device storage.

inSampleSize - Determines how many times image resolution is divided to lower memory usage. Image aspect ratio is not affected by this parameter, just its resolution / quality is lowered.

onBitmapRendered - Overwrite this callback to retrieve Bitmap object rendered once it's ready and perform any other actions needed.

onBitmapRenderFailed - Overwrite this callback to perform actions when Bitmap object fails to render. Can be null.

epicBitmapCache - Cache to check if bitmap has already been rendered.
