Detailed Description

Draw a number of pixels at random positions.

Paint a specific number of pixels at random positions in a given colour.

Example:

Procedural::TextureBuffer bufferSolid(256);
Procedural::Solid(&bufferSolid).setColour(Ogre::ColourValue(0.0f, 0.5f, 1.0f, 1.0f)).process();
Procedural::RandomPixels(&bufferSolid).setColour(Ogre::ColourValue::Red).setCount(200).process();

Constructor & Destructor Documentation

RandomPixels()

Procedural::RandomPixels::RandomPixels

(

TextureBufferPtr

pBuffer

)

Default constructor.

Parameters

pBuffer

Image buffer where to modify the image.

References Ogre::Math::Sqrt().

Member Function Documentation

getName()

Ogre::String Procedural::TextureProcessing::getName ( )

inherited

Get name of the filter as string.

logMsg()

void Procedural::TextureProcessing::logMsg ( Ogre::String  msg )

protectedinherited

process()

TextureBufferPtr Procedural::RandomPixels::process ( )

virtual

Run image manipulation.

Returns

Pointer to image buffer which has been set in the constructor.

Implements Procedural::TextureProcessing.

setColour() [1/2]

RandomPixels& Procedural::RandomPixels::setColour

(

Ogre::ColourValue

colour

)

Set the colour of the pixel to paint.

Parameters

colour

New colour for painting pixels (default Ogre::ColourValue::White)

setColour() [2/2]

RandomPixels& Procedural::RandomPixels::setColour	(	Ogre::Real	red,
		Ogre::Real	green,
		Ogre::Real	blue,
		Ogre::Real	alpha = 1.0f
	)

Set the colour of the pixel to paint.

Parameters

red	Red value of the pixel colour [0.0, 1.0] (default 1.0)
green	Green value of the pixel colour [0.0, 1.0] (default 1.0)
blue	Blue value of the pixel colour [0.0, 1.0] (default 1.0)
alpha	Alpha value of the pixel colour [0.0, 1.0] (default 1.0)

setCount()

RandomPixels& Procedural::RandomPixels::setCount

(

Ogre::uint

count

)

Set the number of random painted pixels.

Parameters

count

Number of pixels to paint (maximum: image height * image weight, default: (Sqrt(image width) + Sqrt(image height)) * 10)

setLog()

void Procedural::TextureProcessing::setLog ( bool  enable = true )

inherited

Enable/Disable logging.

Parameters

enable

true enables logging of filter actions

setSeed()

RandomPixels& Procedural::RandomPixels::setSeed

(

Ogre::uint

seed

)

Set the seed for "random" number generator.

Parameters

seed	Seed value where to set the random number generator (default 5120)
