## Detailed Description

This class encapsulates the concept of a platform-dependent animation.

An animation is a sequence of frames of the same size. Sound is not supported by wxAnimation.

Note that on wxGTK wxAnimation is capable of loading the formats supported by the internally-used `gdk-pixbuf` library (typically this means only `wxANIMATION_TYPE_GIF`). On other platforms wxAnimation is always capable of loading both GIF and ANI formats (i.e. both `wxANIMATION_TYPE_GIF` and `wxANIMATION_TYPE_ANI`).

## Constructor & Destructor Documentation

wxAnimation::wxAnimation | ( |  | ) |

Default ctor.

wxAnimation::wxAnimation | ( | const wxAnimation & | anim | ) |

Copy ctor.

wxAnimation::wxAnimation | ( | const wxString & | name,
|  | wxAnimationType | type = `wxANIMATION_TYPE_ANY`
| ) |  |

Loads an animation from a file.

Parameters

  name | The name of the file to load.
  type | See LoadFile() for more info.

| virtual

Destructor.

See Object Destruction for more info.

## Member Function Documentation

virtual int wxAnimation::GetDelay | ( | unsigned int | i | ) | const
| virtual

Returns the delay for the i-th frame in milliseconds.

If `-1` is returned the frame is to be displayed forever.

virtual wxImage wxAnimation::GetFrame | ( | unsigned int | i | ) | const
| virtual

Returns the i-th frame as a wxImage.

This method is not implemented in the native wxGTK implementation of this class and always returns an invalid image there.

virtual unsigned int wxAnimation::GetFrameCount | ( |  | ) | const
| virtual

Returns the number of frames for this animation.

This method is not implemented in the native wxGTK implementation of this class and always returns 0 there.

virtual wxSize wxAnimation::GetSize | ( |  | ) | const
| virtual

Returns the size of the animation.

virtual bool wxAnimation::IsOk | ( |  | ) | const
| virtual

Returns true if animation data is present.

virtual bool wxAnimation::Load | ( | wxInputStream & | stream,
|  | wxAnimationType | type = `wxANIMATION_TYPE_ANY`
| ) |  |
| virtual

Loads an animation from the given stream.

Parameters

  stream | The stream to use to load the animation. Under wxGTK may be any kind of stream; under other platforms this must be a seekable stream.
  type | One of the wxAnimationType enumeration values.

Returns
  true if the operation succeeded, false otherwise.

virtual bool wxAnimation::LoadFile | ( | const wxString & | name,
|  | wxAnimationType | type = `wxANIMATION_TYPE_ANY`
| ) |  |
| virtual

Loads an animation from a file.

Parameters

  name | A filename.
  type | One of the wxAnimationType values; wxANIMATION_TYPE_ANY means that the function should try to autodetect the filetype.

Returns
  true if the operation succeeded, false otherwise.

wxAnimation& wxAnimation::operator= | ( | const wxAnimation & | brush | ) |

Assignment operator, using reference counting.
