Methods Summary¶

`__init__`
`Clone`	Create a copy of this decoder.
`ConvertToImage`	Convert given frame to wx.Image.
`DoCanRead`	Checks the signature of the data in the given stream and returns `True` if it appears to be a valid animation format recognized by the animation decoder; this function should modify the stream current position without taking care of restoring it since `CanRead` will do it.
`GetDelay`	Return the number of milliseconds this frame should be displayed.
`GetDisposalMethod`	What should be done after displaying this frame.
`GetFramePosition`
`GetFrameSize`
`GetTransparentColour`	The transparent colour for this frame, if any, or `NullColour` .
`GetType`	Return the animation type this decoder implements.
`Load`	Load the animation image frames from the given stream.

Possible constructors:

GIFDecoder()

An animation decoder supporting animated GIF files.

Methods¶

__init__(self)¶

Clone(self)¶

Create a copy of this decoder.

Return type:: wx.adv.AnimationDecoder

ConvertToImage(self, frame, image)¶

Convert given frame to wx.Image.

Parameters:

frame (int) –
image (wx.Image) –

Return type:

bool

DoCanRead(self, stream)¶

Checks the signature of the data in the given stream and returns True if it appears to be a valid animation format recognized by the animation decoder; this function should modify the stream current position without taking care of restoring it since CanRead will do it.

Parameters:: stream (wx.InputStream) –
Return type:: bool

GetDelay(self, frame)¶

Return the number of milliseconds this frame should be displayed.

If -1 is returned then the frame must be displayed forever.

Parameters:: frame (int) –
Return type:: long

GetDisposalMethod(self, frame)¶

What should be done after displaying this frame.

Parameters:: frame (int) –
Return type:: wx.adv.AnimationDisposal

GetFramePosition(self, frame)¶

Parameters:: frame (int) –
Return type:: Point

GetFrameSize(self, frame)¶

Parameters:: frame (int) –
Return type:: Size

GetTransparentColour(self, frame)¶

The transparent colour for this frame, if any, or NullColour .

Parameters:: frame (int) –
Return type:: Colour

GetType(self)¶

Return the animation type this decoder implements.

Return type:: wx.adv.AnimationType

Load(self, stream)¶

Load the animation image frames from the given stream.

Parameters:: stream (wx.InputStream) –
Return type:: bool
