Bitmap (const Bitmap &bitmap) |
Class providing bitmap manipulation (drawing, etc) functions. Creates a new internal bitmap data array and uses it to draw onto.

Constructor.
width | The width of the bitmap. | |
height | The height of the bitmap. |
virtual WoopsiUI::Bitmap::~Bitmap | ( | ) | [inline, virtual] |
Destructor.
WoopsiUI::Bitmap::Bitmap | ( | const Bitmap & | bitmap | ) | [inline, protected] |
Copy constructor is protected to prevent usage.

y | The y co-ordinate of the pixel. |
Implements WoopsiUI::BitmapBase.
Graphics* WoopsiUI::Bitmap::newGraphics | ( | ) |
Get a new graphics object that can draw to this bitmap. Object must be deleted when it is no longer needed.
void WoopsiUI::Bitmap::setPixel | ( | const s16 | x, | |
const s16 | y, | |||
const u16 | colour | |||
) | [virtual] |
