Member Enumeration Documentation

enum MGD::DEVICE_MEM32::FORMAT

Memory format.

Enumerator:

FORMAT_Default
FORMAT_PadTo8	Pad rows to 8-byte boundary.
FORMAT_Invert	Invert rows in memory so first bottom row is first in buffer.

Member Function Documentation

ERRVALUE MGD::DEVICE_MEM32::CreateFrameBuffers

(

UINT16

NumFrameBuffers = 1

)

[protected]

Create frame buffers.

Parameters:

NumFrameBuffers

Number of frame buffers

void MGD::DEVICE_MEM32::EraseFrameBuffer

(

UINT16

FrameBuffer

)

Erase specified frame buffer, setting contents to 0's.

Parameters:

FrameBuffer

Frame buffer index

void MGD::DEVICE_MEM32::EraseFrameBuffers

(

)

Erase all frame buffers, setting contents to 0's.

void MGD::DEVICE_MEM32::FindMinimalRectangle	(	UINT16	FrameBuffer,
		LRECT2D &	rectangle
	)			const

Find minimal rectangle containing all pixels with non-zero alpha values in specified frame buffer.

Parameters:

rectangle

Frame buffer index Rectangle returned

void MGD::DEVICE_MEM32::FindMinimalRectangle

(

LRECT2D &

rectangle

)

const

Find minimal rectangle containing all pixels with non-zero alpha values in any frame buffer.

Parameters:

rectangle

Rectangle returned

FORMAT MGD::DEVICE_MEM32::GetFormat

(

)

const [inline, protected]

Get memory format.

UINT32 MGD::DEVICE_MEM32::GetNumBytesPerRow

(

)

const [inline, protected]

Get number of memory bytes per row.

ERRVALUE MGD::DEVICE_MEM32::ResizeFrameBuffers

(

)

[protected]

Resize all frame buffers to match current device dimensions.

void MGD::DEVICE_MEM32::SetFormat

(

FORMAT

format

)

[protected]

Set memory format.

Must be done before creating frame buffers, typically in derived class Create method.

virtual CAPABILITY MGD::DEVICE_MEM32::v_GetCapabilities

(

)

const [protected, virtual]

Return a list of the capabilities of this device.

Derived class should bitwise-OR with result of base method.

Reimplemented from MGD::DEVICE.
