## Protected Member Functions

virtual bool | DoCanRead (wxInputStream &stream) const
| 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. More...

## Member Function Documentation

## ◆ Clone()

virtual wxAnimationDecoder* wxANIDecoder::Clone | ( |  | ) | const

virtual

Create a copy of this decoder.

Implements wxAnimationDecoder.

## ◆ ConvertToImage()

virtual bool wxANIDecoder::ConvertToImage | ( | unsigned int | frame,
|  | wxImage * | image
| ) |  | const

virtual

Convert given frame to `wxImage`.

Implements wxAnimationDecoder.

## ◆ DoCanRead()

virtual bool wxANIDecoder::DoCanRead | ( | wxInputStream & | stream | ) | const

protectedvirtual

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.

Implements wxAnimationDecoder.

## ◆ GetDelay()

virtual long wxANIDecoder::GetDelay | ( | unsigned int | frame | ) | const

virtual

Return the number of milliseconds this frame should be displayed.

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

Implements wxAnimationDecoder.

## ◆ GetDisposalMethod()

virtual wxAnimationDisposal wxANIDecoder::GetDisposalMethod | ( | unsigned int | frame | ) | const

virtual

What should be done after displaying this frame.

Implements wxAnimationDecoder.

## ◆ GetFramePosition()

virtual wxPoint wxANIDecoder::GetFramePosition | ( | unsigned int | frame | ) | const

virtual

Implements wxAnimationDecoder.

## ◆ GetFrameSize()

virtual wxSize wxANIDecoder::GetFrameSize | ( | unsigned int | frame | ) | const

virtual

Implements wxAnimationDecoder.

## ◆ GetTransparentColour()

virtual wxColour wxANIDecoder::GetTransparentColour | ( | unsigned int | frame | ) | const

virtual

The transparent colour for this frame, if any, or `wxNullColour`.

Implements wxAnimationDecoder.

## ◆ GetType()

virtual wxAnimationType wxANIDecoder::GetType | ( |  | ) | const

virtual

Return the animation type this decoder implements.

Implements wxAnimationDecoder.

## ◆ Load()

virtual bool wxANIDecoder::Load | ( | wxInputStream & | stream | ) |

virtual

Load the animation image frames from the given stream.

Implements wxAnimationDecoder.
