Constructor & Destructor Documentation
| gnash::GifImageInput::GifImageInput | ( | boost::shared_ptr< IOChannel > | in | ) |
Construct a GifImageInput object to read from an IOChannel.
- Parameters:
-
in The stream to read GIF data from. Ownership is shared between caller and GifImageInput, so it is freed automatically when the last owner is destroyed.
Referenced by create().

Member Function Documentation
| static DSOEXPORT std::auto_ptr<ImageInput> gnash::GifImageInput::create | ( | boost::shared_ptr< IOChannel > | in | ) | [inline, static] |
Create a GifImageInput and transfer ownership to the caller.
- Parameters:
-
in The IOChannel to read GIF data from.
References GifImageInput().
| size_t gnash::GifImageInput::getComponents | ( | ) | const [inline, virtual] |
Get number of components (channels).
- Returns:
- The number of components, e.g. 3 for RGB
Implements gnash::ImageInput.
| size_t gnash::GifImageInput::getHeight | ( | ) | const [virtual] |
Get the image's height in pixels.
- Returns:
- The height of the image in pixels.
Implements gnash::ImageInput.
| size_t gnash::GifImageInput::getWidth | ( | ) | const [virtual] |
Get the image's width in pixels.
- Returns:
- The width of the image in pixels.
Implements gnash::ImageInput.
| void gnash::GifImageInput::read | ( | ) | [virtual] |
Begin processing the image data.
Implements gnash::ImageInput.
| void gnash::GifImageInput::readScanline | ( | unsigned char * | rgb_data | ) | [virtual] |
Read a scanline's worth of image data into the given buffer.
The amount of data read is getWidth() * getComponents().
- Parameters:
-
rgbData The buffer for writing raw RGB data to.
Implements gnash::ImageInput.
