Detailed Description
This is the abstract basis class for an image writer.
Image Writers are implemented by the front end, i.e. the application which uses the engine. If a pixel is rendered this interface is called to deliver pixels to the output.

void ImageWriter::finishWriter (

|
void ImageWriter::initWriter (
|
Area area,
|
|
int nChannels ) [pure virtual]

|
This method has to be called before any pixel is given to the implementation with writePixels.
It defines the maximum range of pixels the engine intends to write. Implementation can allocate space for caching data. -
Parameters:
-
|
|
void ImageWriter::writePixels (
|
Area area,
|
|
unsigned short * pData,
|
|
bool bAreaFinal ) [pure virtual]
|
|
|
|
The engine delivers a bulk of pixels to the front end with this method.
The area defines how many pixels are delivered an where they are located within the picture. -
Parameters:
-
