Detailed Description

Filter: represents a filter and its configuration.

A filter is identified by an internal name. The configuration for each filter is defined as an InfoObject: a map of name and value pairs.

Currently available filters are:

'autocontrast', 'blur', 'bottom edge detections', 'brightnesscontrast', 'burn', 'colorbalance', 'colortoalpha', 'colortransfer', 'desaturate', 'dodge', 'emboss', 'emboss all directions', 'emboss horizontal and vertical', 'emboss horizontal only', 'emboss laplascian', 'emboss vertical only', 'gaussian blur', 'gaussiannoisereducer', 'gradientmap', 'halftone', 'hsvadjustment', 'indexcolors', 'invert', 'left edge detections', 'lens blur', 'levels', 'maximize', 'mean removal', 'minimize', 'motion blur', 'noise', 'normalize', 'oilpaint', 'perchannel', 'phongbumpmap', 'pixelize', 'posterize', 'raindrops', 'randompick', 'right edge detections', 'roundcorners', 'sharpen', 'smalltiles', 'sobel', 'threshold', 'top edge detections', 'unsharp', 'wave', 'waveletnoisereducer']

Constructor & Destructor Documentation

◆ Filter()

Filter::Filter ( )
explicit

Filter: create an empty filter object.

Until a name is set, the filter cannot be applied.

Definition at line 37 of file Filter.cpp.

Member Function Documentation

◆ apply

bool Filter::apply ( Node node,
int  x,
int  y,
int  w,
int  h 
)
slot

Apply the filter to the given node.

Parameters
nodethe node to apply the filter to
x
y
w
hdescribe the rectangle the filter should be apply. This is always in image pixel coordinates and not relative to the x, y of the node.
Returns
true if the filter was applied successfully, or false if the filter could not be applied because the node is locked or does not have an editable paint device.

Definition at line 85 of file Filter.cpp.

◆ configuration

InfoObject * Filter::configuration ( ) const
slot
Returns
the configuration object for the filter

Definition at line 75 of file Filter.cpp.

◆ name

QString Filter::name ( ) const
slot

name the internal name of this filter.

Returns
the name.

Definition at line 61 of file Filter.cpp.

◆ setConfiguration

void Filter::setConfiguration ( InfoObject value)
slot

setConfiguration set the configuration object for the filter

Definition at line 80 of file Filter.cpp.

◆ setName

void Filter::setName ( const QString name)
slot

setName set the filter's name to the given name.

Definition at line 66 of file Filter.cpp.

◆ startFilter

bool Filter::startFilter ( Node node,
int  x,
int  y,
int  w,
int  h 
)
slot

startFilter starts the given filter on the given node.

Parameters
nodethe node to apply the filter to
x
y
w
hdescribe the rectangle the filter should be apply. This is always in image pixel coordinates and not relative to the x, y of the node.
