Method Detail

add

public static android.graphics.PointF add(android.graphics.PointF lhs,
                                          android.graphics.PointF rhs)

sub

public static android.graphics.PointF sub(android.graphics.PointF lhs,
                                          android.graphics.PointF rhs)

sink

public static android.graphics.RectF sink(android.graphics.RectF in)

Converts a sub-pixel accurate RectF to a single pixel accurate rect. This is helpful for clipping operations which dont do a good job with subpixel vals.

Parameters:

in -

Returns:

nearestPixRect

public static android.graphics.RectF nearestPixRect(float left,
                                                    float top,
                                                    float right,
                                                    float bottom)

dpToPix

public static float dpToPix(android.content.Context context,
                            float dp)

Converts a dp value to pixels.

Parameters:

context -

dp -

Returns:

fractionToPixH

public static float fractionToPixH(android.content.Context context,
                                   float fraction)

Parameters:

context -

fraction - A float value between 0 and 1.

Returns:

Number of pixels fraction represents on the current device's display.

fractionToPixW

public static float fractionToPixW(android.content.Context context,
                                   float fraction)

Parameters:

context -

fraction - A float value between 0 and 1.

Returns:

Number of pixels fraction represents on the current device's display.
