References data, Data(), cSize::Height(), MALLOC, size, Size(), and cSize::Width().
Creates an image with the given Size and allocates the necessary memory to copy the pixels pointed to by Data, which is a sequence of (Size.Width() * Size.Height()) tColor values.
If Data is NULL, the allocated memory is not initialized. The alpha value of the Image's pixels is taken into account, so it has to be greater than 0 for the image to be visible.

void cImage::Fill | ( | tColor | Color | ) |
Returns the pixel value at the given Point.
For performance reasons there is no range check here, so the caller must make sure that the Point is within the images size.

Sets the pixel at the given Point to Color.
For performance reasons there is no range check here, so the caller must make sure that the Point is within the images size.
