References data.

cImage::cImage ( const cImage Image)

References data, Data(), cSize::Height(), MALLOC, size, Size(), and cSize::Width().

cImage::cImage ( const cSize Size,
const tColor Data = NULL 
)

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.
