Member Function Documentation

◆ getLineInfo()

const void * openmsx::RawFrame::getLineInfo	(	unsigned	line,
		unsigned &	lineWidth,
		void *	buf,
		unsigned	bufWidth
	)		const

overrideprotectedvirtual

Abstract implementation of getLinePtr().

Pixel type is unspecified (implementations that care about the exact type should get it via some other mechanism).

Parameters

line	The line number for the requested line.
lineWidth	Output parameter, the width of the returned line in pixel units.
buf	Buffer space that can optionally be used by the implementation.
bufWidth	The size of the above buffer, in pixel units.

Returns: Pointer to the first pixel of the requested line. This might be the same as the given 'buf' parameter or it might be some internal buffer.

Implements openmsx::FrameSource.

Definition at line 40 of file RawFrame.cc.

◆ getLinePtrDirect()

template<typename Pixel >

Pixel* openmsx::RawFrame::getLinePtrDirect ( unsigned y )

inline

Definition at line 19 of file RawFrame.hh.

References openmsx::MemBuffer< T, ALIGNMENT >::data().

◆ getLineWidth()

unsigned openmsx::RawFrame::getLineWidth ( unsigned line ) const

overrideprotectedvirtual

Gets the number of display pixels on the given line.

Returns: line width (=1 for a vertical border line)

Implements openmsx::FrameSource.

Definition at line 34 of file RawFrame.cc.

References openmsx::FrameSource::getHeight().

◆ getLineWidthDirect()

unsigned openmsx::RawFrame::getLineWidthDirect ( unsigned y ) const

inline

Definition at line 23 of file RawFrame.hh.

◆ getRowLength()

unsigned openmsx::RawFrame::getRowLength ( ) const

overridevirtual

Returns the distance (in pixels) between two consecutive lines.

Is meant to be used in combination with getMultiLinePtr(). The result is only meaningful when hasContiguousStorage() returns true (also only in that case does getMultiLinePtr() return more than 1 line).

Reimplemented from openmsx::FrameSource.

Definition at line 49 of file RawFrame.cc.

◆ hasContiguousStorage()

bool openmsx::RawFrame::hasContiguousStorage ( ) const

overrideprotectedvirtual

Returns true when two consecutive rows are also consecutive in memory.

Reimplemented from openmsx::FrameSource.

Definition at line 54 of file RawFrame.cc.

◆ setBlank()

template<typename Pixel >

void openmsx::RawFrame::setBlank	(	unsigned	line,
		Pixel	color
	)

inline

Definition at line 34 of file RawFrame.hh.
