Method Detail

reset

public void reset()

ready

public boolean ready()

setIntrinsicVideoSize

public void setIntrinsicVideoSize(int width,
                                  int height)

getCurrentRotation

public int getCurrentRotation()

getCurrentScaleType

@NonNull
public ScaleType getCurrentScaleType()

rotate

public void rotate(@NonNull
                   android.view.View view,
                   int rotation)

scale

public boolean scale(@NonNull
                     android.view.View view,
                     @NonNull
                     ScaleType scaleType)

Performs the requested scaling on the view's matrix

Parameters:

view - The View to alter the matrix to achieve the requested scale type

scaleType - The type of scaling to use for the specified view

Returns:

True if the scale was applied

applyCenter

protected void applyCenter(@NonNull
                           android.view.View view)

Applies the ScaleType.CENTER to the specified matrix. This will perform no scaling as this just indicates that the video should be centered in the View

Parameters:

view - The view to apply the transformation to

applyCenterCrop

protected void applyCenterCrop(@NonNull
                               android.view.View view)

Applies the ScaleType.CENTER_CROP to the specified matrix. This will make sure the smallest side fits the parent container, cropping the other

Parameters:

view - The view to apply the transformation to

applyCenterInside

protected void applyCenterInside(@NonNull
                                 android.view.View view)

Applies the ScaleType.CENTER_INSIDE to the specified matrix. This will only perform scaling if the video is too large to fit completely in the view in which case it will be scaled to fit

Parameters:

view - The view to apply the transformation to

applyFitCenter

protected void applyFitCenter(@NonNull
                              android.view.View view)

Applies the ScaleType.FIT_CENTER to the specified matrix. This will scale the video so that the largest side will always match the view

Parameters:

view - The view to apply the transformation to

setScale

protected void setScale(@NonNull
                        android.view.View view,
                        float xScale,
                        float yScale)

Applies the specified scale modification to the view

Parameters:

view - The view to scale

xScale - The scale to apply to the x axis

yScale - The scale to apply to the y axis

applyRequestedModifications

protected void applyRequestedModifications()

Applies any scale or rotation that was requested before the MatrixManager was ready to apply those modifications.
