Public Constructors

public AnimatedDrawableUtil()

Public Methods

public void fixFrameDurations(int[] frameDurationMs)

Adjusts the frame duration array to respect logic for minimum frame duration time.

Parameters

| frameDurationMs | the frame duration array |

public int getFrameForTimestampMs(int[] frameTimestampsMs, int timestampMs)

Gets the frame index for specified timestamp.

Parameters

| frameTimestampsMs | an array of timestamps generated by `` | | timestampMs | the timestamp |

Returns

• the frame index for the timestamp or the last frame number if the timestamp is outside the duration of the entire animation

public int[] getFrameTimeStampsFromDurations(int[] frameDurationsMs)

Given an array of frame durations, generate an array of timestamps corresponding to when each frame beings.

Parameters

| frameDurationsMs | an array of frame durations |

Returns

• an array of timestamps

public int getSizeOfBitmap(Bitmap bitmap)

public int getTotalDurationFromFrameDurations(int[] frameDurationMs)

Gets the total duration of an image by summing up the duration of the frames.

Parameters

| frameDurationMs | the frame duration array |

Returns

• the total duration in milliseconds

public static boolean isOutsideRange(int startFrame, int endFrame, int frameNumber)

Checks whether the specified frame number is outside the range inclusive of both start and end. If start <= end, start is within, end is within, and everything in between is within. If start > end, start is within, end is within, everything less than start is within and everything greater than end is within. This behavior is useful for handling the wrapping case.

Parameters

| startFrame | the start frame | | endFrame | the end frame | | frameNumber | the frame number |

Returns

• whether the frame is outside the range of [start, end]
