Frees all resources owned by the object prior to its destruction.

This method is called when you are about to start direct drawing to the bitmap memory. Calls to DrawingBegin() must be paired with a subsequent call to DrawingEnd() . Also, code must not leave between a DrawingBegin() - DrawingEnd() pair. CFbsBitmapDevice::DrawingEnd()

This method is called when you have finished direct drawing to the bitmap memory. Calls to DrawingEnd() must correspond to a prior call to DrawingBegin() . CFbsBitmapDevice::DrawingBegin()

Gets the device's current palette.

This function is only supported if the device has a modifiable palette, which can be determined by calling PaletteAttributes() .

The function provides a concrete implementation of the pure virtual function CGraphicsDevice::GetPalette() .

Gets the RGB colour of an individual pixel on a bitmapped graphics device.

The function provides a concrete implementation of the pure virtual function CBitmapDevice::GetPixel() .

Copies a scanline into a buffer.

The function provides a concrete implementation of the pure virtual function CBitmapDevice::GetScanLine() .

Converts a horizontal dimension of a device in pixels to a horizontal dimension in twips.

The function provides a concrete implementation of the pure virtual function MGraphicsDeviceMap::HorizontalPixelsToTwips() .

Converts a horizontal dimension of a device in twips to a horizontal dimension in pixels.

The function provides a concrete implementation of the pure virtual function MGraphicsDeviceMap::HorizontalTwipsToPixels() .

Allocates and constructs the device with the bitmap. Also creates a 2D graphics accelerator which is owned and used by the device.

Constructs the object from the specified Font and Bitmap server managed bitmap.

Gets the palette attributes of the device.

The function provides a concrete implementation of the pure virtual function CGraphicsDevice::PaletteAttributes() .

Resizes the device.

Sets the bit level.

Sets the device's palette to the specified palette.

Setting the palette is only possible if the device has a modifiable palette, which can be determined by calling PaletteAttributes() .

The function provides a concrete implementation of the pure virtual function CGraphicsDevice::SetPalette() .

Gets the size of the device, in twips.

The method swaps bitmap device's width and height. For example: if the size is (40, 20), the swapped size will be (20, 40). The device's content is not preserved. The method leaves CFbsBitmapDevice object in a consistent state - scaling settings will be set with their default values (the scaling is switched off), the device's dither origin will be set to (0,0), scaling origin to (0,0).

Note: If the device was scaled or its dither origin was set with a non-default value, it has to be rescaled again, respectivelly the dither origin has to be set again.

Note: All graphics contexts, already created by the device, should be re-activated calling CFbsBitGc::Activate() .

Note: Do not call SwapWidthAndHeight() between DrawingBegin() and DrawingEnd() calls!

Converts a vertical dimension of a device in pixels to a vertical dimension in twips.

The function provides a concrete implementation of the pure virtual function MGraphicsDeviceMap::VerticalPixelsToTwips() .

Converts a vertical dimension of a device in twips to a vertical dimension in pixels.

The function provides a concrete implementation of the pure virtual function MGraphicsDeviceMap::VerticalTwipsToPixels() .
