Detailed Description

template<bool DIR = true, class R = WindowCore>
class drain::image::GaussianStripe< DIR, R >

Template Parameters

DIR	- direction: true=horzizontal, false=vertical
R	- Core for window input & output images

Member Function Documentation

initialize()

template<bool DIR = true, class R = WindowCore>

void initialize ( )

inlinevirtual

This function \i must

1. set image limits (limits of the total scanning area)
2. set (initial) loop limits (limits of the window scanning area. Typically window origin is in the center.
3. set starting location (typically 0,0)

Reimplemented from Window< C, R >.

setImageLimits()

template<bool DIR = true, class R = WindowCore>

virtual void setImageLimits ( ) const

inlinevirtual

Sets internal limits corresponding to image geometries. Typically using coordHandler.

Studies source image(s) and sets srcWidth, srcHeight and coordHandler. Consider already implemented methods like WindowCore::adjustCoordHandler()

Implements Window< C, R >.

setSize()

template<bool DIR = true, class R = WindowCore>

virtual void setSize ( size_t  width, size_t  height  )

inlineprotectedvirtual

Sets the window size.

Reimplemented from Window< C, R >.

update() [1/5]

void update ( )

protectedvirtual

At each location, this is called to calculate and store something in members.

Reimplemented from Window< C, R >.

Reimplemented in GaussianStripeVertPolarWeighted.

update() [2/5]

void update ( )

protectedvirtual

At each location, this is called to calculate and store something in members.

Reimplemented from Window< C, R >.
