◆ renderSceneToScreen()

void ZVision::RenderManager::renderSceneToScreen ( )

Renders the scene to the screen

◆ renderImageToBackground() [1/3]

void ZVision::RenderManager::renderImageToBackground	(	const Common::Path &	fileName,
		int16	destinationX,
		int16	destinationY
	)

Blits the image or a portion of the image to the background.

Parameters

fileName	Name of the image file
destinationX	X position where the image should be put. Coords are in working window space, not screen space!
destinationY	Y position where the image should be put. Coords are in working window space, not screen space!

◆ renderImageToBackground() [2/3]

void ZVision::RenderManager::renderImageToBackground	(	const Common::Path &	fileName,
		int16	destX,
		int16	destY,
		uint32	colorkey
	)

Blits the image or a portion of the image to the background.

Parameters

fileName	Name of the image file
destX	X position where the image should be put. Coords are in working window space, not screen space!
destY	Y position where the image should be put. Coords are in working window space, not screen space!
colorkey	Transparent color

◆ renderImageToBackground() [3/3]

void ZVision::RenderManager::renderImageToBackground	(	const Common::Path &	fileName,
		int16	destX,
		int16	destY,
		int16	keyX,
		int16	keyY
	)

Blits the image or a portion of the image to the background.

Parameters

fileName	Name of the image file
destX	X position where the image should be put. Coords are in working window space, not screen space!
destY	Y position where the image should be put. Coords are in working window space, not screen space!
keyX	X position of transparent color
keyY	Y position of transparent color

◆ setBackgroundImage()

void ZVision::RenderManager::setBackgroundImage ( const Common::Path & fileName )

Sets the current background image to be used by the RenderManager and immediately blits it to the screen. (It won't show up until the end of the frame)

Parameters

fileName The name of the image file

◆ setBackgroundPosition()

void ZVision::RenderManager::setBackgroundPosition ( int offset )

Set the background position (_backgroundOffset). If the current RenderState is PANORAMA, the offset will be in the horizontal direction. If the current RenderState is TILT, the offset will be in the vertical direction.

This method will not render anything on the screen. So if nothing else is called that renders the background, the change won't be seen until next frame.

Parameters

offset The amount to offset the background

◆ screenSpaceToImageSpace()

const Common::Point ZVision::RenderManager::screenSpaceToImageSpace ( const Common::Point & point )

Converts a point in screen coordinate space to image coordinate space

Parameters

point Point in screen coordinate space

Returns: Point in image coordinate space

◆ tranposeSurface()

static Graphics::Surface* ZVision::RenderManager::tranposeSurface ( const Graphics::Surface * surface )

static

Creates a copy of surface and transposes the data.

Note: The user is responsible for calling free() on the returned surface and then deleting it

Parameters

surface The data to be transposed

Returns: A copy of the surface with the data transposed

◆ readImageToSurface() [1/2]

void ZVision::RenderManager::readImageToSurface	(	const Common::Path &	fileName,
		Graphics::Surface &	destination
	)

Reads an image file pixel data into a Surface buffer. Also, if the image is transposed, it will un-transpose the pixel data. The function will call destination::create() if the dimensions of destination do not match up with the dimensions of the image.

Parameters

fileName	The name of a .tga file
destination	A reference to the Surface to store the pixel data in

◆ readImageToSurface() [2/2]

void ZVision::RenderManager::readImageToSurface	(	const Common::Path &	fileName,
		Graphics::Surface &	destination,
		bool	transposed
	)

Reads an image file pixel data into a Surface buffer. Also, if the image is transposed, it will un-transpose the pixel data. The function will call destination::create() if the dimensions of destination do not match up with the dimensions of the image.

Parameters

fileName	The name of a .tga file
destination	A reference to the Surface to store the pixel data in
transposed	Transpose flag
