Member Function Documentation

◆ getVideoSource()

int openmsx::VideoLayer::getVideoSource ( ) const

Returns the ID for this VideoLayer.

These IDs are globally unique. The 'videosource' setting uses these IDs as possible values.

◆ takeRawScreenShot()

virtual void openmsx::VideoLayer::takeRawScreenShot	(	unsigned	height,
		const std::string &	filename
	)

pure virtual

Create a raw (=non-post-processed) screenshot.

The 'height' parameter should be either '240' or '480'. The current image will be scaled to '320x240' or '640x480' and written to a png file.

Implemented in openmsx::PostProcessor.

◆ update()

void openmsx::VideoLayer::update ( const Setting & setting )

overrideprotectedvirtualnoexcept

Implements openmsx::Observer< Setting >.
