方法详细资料

getBackgroundColor

public final int getBackgroundColor(int index)

Returns the background color of the first frame in this GIF image. If the frame has a local color table, the returned color will be from that table. If not, the color will be from the global color table. Returns 0 if there is neither a local nor a global color table.

参数:

index - Index of the current frame, 0 to N-1

返回:

32 bit ARGB color in the form 0xAARRGGBB

getDelay

public final int getDelay(int index)

If not 0, the delay specifies how many hundredths (1/100) of a second to wait before displaying the frame after the current frame.

参数:

index - Index of the current frame, 0 to N-1

返回:

Delay as number of hundredths (1/100) of a second

getFrame

public final BufferedImage getFrame(int index)

参数:

index - Index of the frame to return as image, starting from 0. For incremental calls such as [0, 1, 2, ...] the method's run time is O(1) as only one frame is drawn per call. For random access calls such as [7, 12, ...] the run time is O(N+1) with N being the number of previous frames that need to be drawn before N+1 can be drawn on top. Once a frame has been drawn it is being cached and the run time is more or less O(0) to retrieve it from the list.

返回:

A BufferedImage for the specified frame.

getFrameCount

public final int getFrameCount()

返回:

The number of frames contained in this GIF image

getHeight

public final int getHeight()

返回:

The height of the GIF image

getWidth

public final int getWidth()

返回:

The width of the GIF image
