Commits the changes made to the current bitmap by flushing the buffer.

This is a virtual function that each derived class must implement.

Initialises internal data structures prior to conversion.

This is a virtual function that each derived class must implement.

Initialises internal data structures prior to the manipulation of the specified pixel block.

This overloaded version allows specification of a block size for those formats which support blocked pixel data eg. JPEG

This is a virtual function that each derived class must implement.

Sets the number times the current line should be repeated. The lines are repeated in the same direction as set by SetYPosIncrement(). This is used to fill blank lines when rendering interlaced images. eg GIF.

Sets the pixel at the current position to aGray256.

This is a virtual function that each derived class must implement.

Sets a specified number of pixels to the specified greyscale value.

For image types which support blocking of pixels eg JPEG, the current pixel block is set using the data supplied in aGray256Buffer.

This is a virtual function that each derived class must implement.

Sets the number of pixels specified by aCount to the value given by aGray256, starting at the current position.

This is a virtual function that each derived class must implement.

Updates the bitmap with greyscale information from the array of greyscale values.

The array of values supplied by aGray256Buffer, whose length is specified in aBufferLength, is used to update successive pixels with the greyscales values.

This is a virtual function that each derived class must implement.

Sets the pixel at the current position to aColor.

This is a virtual function that each derived class must implement.

Sets the current pixel block using the data supplied in aColorBuffer.

Note: For use with image types that support blocking of pixels eg JPEG.

This is a virtual function that each derived class must implement.

Sets the pixel padding to the value specified by aNumberOfPixels.

This is a virtual function that each derived class must implement.

Sets aCount number of pixels to the value given by aColor, starting at the current position.

This is a virtual function that each derived class must implement.

Updates the bitmap with colour information from the array of colour values.

Uses the array of colour values supplied by aColorBuffer, whose length is specified by aBufferLength, to update successive pixels with values in the buffer, starting at the current position.

This is a virtual function that each derived class must implement.

Sets the current position in the bitmap to aPosition.

This is a virtual function that each derived class must implement.

Sets the number of pixels by which to increment the current position in the Y-axis. This is used when rendering images supporting interlacing. eg GIF

This is a virtual function that each derived class must implement.
