Member Function Documentation

drawBorder()

virtual void openmsx::V9990Rasterizer::drawBorder ( int  fromX, int  fromY, int  limitX, int  limitY  )

pure virtual

Render a rectangle of border pixels on the host screen.

The units are absolute lines (Y) and V9990 UC ticks (X).

Parameters

fromX	X coordinate of render start (inclusive).
fromY	Y coordinate of render start (inclusive).
limitX	X coordinate of render end (exclusive).
limitY	Y coordinate of render end (exclusive).

Implemented in openmsx::V9990SDLRasterizer.

drawDisplay()

virtual void openmsx::V9990Rasterizer::drawDisplay ( int  fromX, int  fromY, int  toX, int  toY, int  displayX, int  displayY, int  displayYA, int  displayYB  )

pure virtual

Render a rectangle of display pixels on the host screen.

Parameters

fromX	X coordinate of render start in V9990 UC ticks.
fromY	Y coordinate of render start in absolute lines.
toX	X coordinate of render stop in V9990 UC ticks (exclusive).
toY	Y coordinate of render stop in absolute lines (exclusive).
displayX	display coordinate of render start: [0..640).
displayY	display coordinate of render start: [0..480).
displayYA	similar to displayY but specific for plane A
displayYB	similar to displayY but specific for plane B Note: Usually displayY, displayYA and displayYB will all be the same. Only in case the vertical scroll register is updated in the middle of a frame they can differ, see V9990PixelRenderer::updateScrollAYLow()

Implemented in openmsx::V9990SDLRasterizer.

frameEnd()

virtual void openmsx::V9990Rasterizer::frameEnd ( EmuTime::param  time )

pure virtual

Indicates the end of the current frame.

Implemented in openmsx::V9990SDLRasterizer.

frameStart()

virtual void openmsx::V9990Rasterizer::frameStart ( )

pure virtual

Indicates the start of a new frame.

Implemented in openmsx::V9990SDLRasterizer.

getPostProcessor()

virtual PostProcessor * openmsx::V9990Rasterizer::getPostProcessor ( ) const

pure virtual

See V9990::getPostProcessor().

Implemented in openmsx::V9990SDLRasterizer.

isActive()

virtual bool openmsx::V9990Rasterizer::isActive ( )

pure virtual

Will the output of this Rasterizer be displayed? There is no point in producing a frame that will not be displayed.

TODO: Is querying the next pipeline step the best way to solve this, or is it better to explicitly disable the first step in the pipeline?

Implemented in openmsx::V9990SDLRasterizer.

isRecording()

virtual bool openmsx::V9990Rasterizer::isRecording ( ) const

pure virtual

Is video recording active?

Implemented in openmsx::V9990SDLRasterizer.

reset()

virtual void openmsx::V9990Rasterizer::reset ( )

pure virtual

Resynchronize with VDP - flush caches etc.

Implemented in openmsx::V9990SDLRasterizer.

setColorMode()

virtual void openmsx::V9990Rasterizer::setColorMode ( enum V9990ColorMode  colorMode )

pure virtual

The color mode determines how the V9990 VRAM data gets converted to pixel colors.

Parameters

colorMode

The new color mode.

Implemented in openmsx::V9990SDLRasterizer.

setDisplayMode()

virtual void openmsx::V9990Rasterizer::setDisplayMode ( enum V9990DisplayMode  displayMode )

pure virtual

The display mode determines the screens geometry and how V9990 pixels are mapped to pixels on screen.

Parameters

displayMode

The new display mode.

Implemented in openmsx::V9990SDLRasterizer.

setPalette()

virtual void openmsx::V9990Rasterizer::setPalette ( int  index, byte  r, byte  g, byte  b, bool  ys  )

pure virtual

Set RGB values for a palette entry.

Parameters

index	Index in palette
r	Red component intensity (5 bits)
g	Green component intensity (5 bits)
b	Blue component intensity (5 bits)
ys	Is this entry transparent

Implemented in openmsx::V9990SDLRasterizer.

setSuperimpose()

virtual void openmsx::V9990Rasterizer::setSuperimpose ( bool  enabled )

pure virtual

Is superimpose enabled?

Implemented in openmsx::V9990SDLRasterizer.
