Constructor & Destructor Documentation

RE_RasterObject::RE_RasterObject	(	RE_RenderCallback	callback,
		int	w,
		int	h,
		int	tw,
		int	th,
		void *	data
	)

Provide this class with a callback, the width and height you want to render into, the height and width you want the texture to be (this should be a power of two), and some data to be passed to the callback.

RE_RasterObject::~RE_RasterObject

(

)

Be very careful before calling this - do you have an OpenGL context pushed?

Member Function Documentation

bool RE_RasterObject::build

(

RE_Render *

r

)

Render offscreen, calling the render callback.

int RE_RasterObject::getHeight

(

)

const

The height of what you actually want to render.

TIL_Raster* RE_RasterObject::getRaster

(

)

[inline]

int RE_RasterObject::getTexHeight

(

)

const

The texture's height. Should be a power of two.

RE_Texture* RE_RasterObject::getTexture

(

RE_Render *

r

)

Generate and get the OpenGL ID of a texture that contains the contents of what was render when build() was called.

int RE_RasterObject::getTexWidth

(

)

const

The texture's width. Should be a power of two.

int RE_RasterObject::getWidth

(

)

const

The width of what you actually want to render.

bool RE_RasterObject::isBuilt

(

)

const

Whether build() has successfully been called.

void RE_RasterObject::rebuild

(

RE_Render *

r

)

If the color scheme changes, we need to re-render everything.

void RE_RasterObject::renderDirect	(	RE_Render *	r,
		int	x,
		int	y,
		int	w,
		int	h
	)

Renders this object directly using the callback.

void RE_RasterObject::resetBuffer

(

)

Frees the offscreen buffer associated with this object without clearing the other data (texture, raster).

void RE_RasterObject::setForceRaster

(

bool

on

)

[inline]

Force PXL_Raster creation.
