## Constructor & Destructor Documentation

wxTGAHandler::wxTGAHandler | ( |  | ) |

Default constructor for wxTGAHandler.

## Member Function Documentation

virtual bool wxTGAHandler::DoCanRead | ( | wxInputStream & | stream | ) |

protectedvirtual

Called to test if this handler can read an image from the given stream.

NOTE: this function is allowed to change the current stream position since CallDoCanRead() will take care of restoring it later

Implements wxImageHandler.

virtual bool wxTGAHandler::LoadFile | ( | wxImage * | image,
|  | wxInputStream & | stream,
|  | bool | verbose = `true`,
|  | int | index = `-1`
| ) |  |

virtual

Loads a image from a stream, putting the resulting data into image.

If the image file contains more than one image and the image handler is capable of retrieving these individually, index indicates which image to read from the stream.

Parameters

  image | The image object which is to be affected by this operation.
  stream | Opened input stream for reading image data.
  verbose | If set to true, errors reported by the image handler will produce wxLogMessages.
  index | The index of the image in the file (starting from zero).

Returns
  true if the operation succeeded, false otherwise.

Reimplemented from wxImageHandler.

virtual bool wxTGAHandler::SaveFile | ( | wxImage * | image,
|  | wxOutputStream & | stream,
|  | bool | verbose = `true`
| ) |  |

virtual

Saves a image in the output stream.

Parameters

  image | The image object which is to be affected by this operation.
  stream | Opened output stream for writing the data.
  verbose | If set to true, errors reported by the image handler will produce wxLogMessages.

Returns
  true if the operation succeeded, false otherwise.
