Adds a free form given by it's corner coordinates.

static int GLImagePainter::calcTextureSize	(	int	width,
		int	height
	)		[static, private]

calculates the next larger power of two that width and height fit into

void GLImagePainter::clearForms

(

)

Clear the list of painted boxes.

		unsigned	imageWidth,
		unsigned	imageHeight,
		ImageGrabber::ColorFormat	textureFormat
	)		[protected]

void GLImagePainter::paintImage

(

float

alpha = 1.0

)

generate & display texture

void GLImagePainter::paintVectorObjects

(

)

paint all registered boxes / lines / circles

void GLImagePainter::saveImage

(

std::string

filename

)

void GLImagePainter::setAnaglyphImage	(	const puma2::GrayLevelImage8 *	leftYImage,
		const puma2::GrayLevelImage8 *	rightYImage,
		float	aspect = 1.0
	)

void GLImagePainter::setColorImage	(	const puma2::ColorImageRGB8 *	image,
		float	aspect = 1.0
	)

Update the contents of the OpenGL Texture, clear the box list and render the image.

void GLImagePainter::setColorImage	(	const puma2::GrayLevelImage8 *	yImage,
		const puma2::ColorImageUV8 *	uvImage,
		float	aspect = 1.0
	)

void GLImagePainter::setGrayLevelImage	(	const puma2::GrayLevelImage8 *	image,
		float	aspect = 1.0
	)

void GLImagePainter::setPixelAspectRatio

(

float

ratio

)

[inline]

Set the pixel aspect ratio (width/height)

Note:

Default value is 1.0 (quadratic pixels)

Values above 1 will display pixels horizontally stretched
