Detailed Description

Selection represents a selection on Krita.

A selection is not necessarily associated with a particular Node or Image.

from krita import *
d = Application.activeDocument()
n = d.activeNode()
r = n.bounds()
s = Selection()
s.select(r.width() / 3, r.height() / 3, r.width() / 3, r.height() / 3, 255)
s.cut(n)

cut erases the area defined by the selection from the node and puts a copy on the clipboard.

Parameters
nodethe node from which the selection will be cut.

Definition at line 154 of file Selection.cpp.

◆ dilate

void Selection::dilate ( )
slot

Dilate the selection with a radius of 1 pixel.

Definition at line 191 of file Selection.cpp.

slot
Returns
a duplicate of the selection

Definition at line 56 of file Selection.cpp.

slot

Erode the selection with a radius of 1 pixel.

Definition at line 183 of file Selection.cpp.

◆ feather

void Selection::feather ( int radius)
slot

Feather the selection with the given radius.

Definition at line 207 of file Selection.cpp.

◆ grow

void Selection::grow ( int xradius,
int yradius )
slot

Grow the selection with the given radius.

Definition at line 215 of file Selection.cpp.

◆ height

int Selection::height ( ) const
slot
Returns
the height of the selection

Definition at line 68 of file Selection.cpp.

◆ intersect

void Selection::intersect ( Selection * selection)
slot

Intersect the given selection with this selection.

Definition at line 285 of file Selection.cpp.

◆ invert

void Selection::invert ( )
slot

Invert the selection.

Definition at line 241 of file Selection.cpp.

◆ move

void Selection::move ( int x,
int y )
slot

Definition at line 94 of file Selection.cpp.

◆ operator!=()

bool Selection::operator!= ( const Selection & other) const

Definition at line 51 of file Selection.cpp.

◆ operator==()

bool Selection::operator== ( const Selection & other) const

Definition at line 46 of file Selection.cpp.

◆ paste

void Selection::paste ( Node * destination,
int x,
int y )
slot

paste pastes the content of the clipboard to the given node, limited by the area of the current selection.

Parameters
destinationthe node where the pixels will be written
xthe x position at which the clip will be written
ythe y position at which the clip will be written

Definition at line 166 of file Selection.cpp.

◆ pixelData

QByteArray Selection::pixelData ( int x,
int y,
int w,
int h ) const
slot

pixelData reads the given rectangle from the Selection's mask and returns it as a byte array.

The pixel data starts top-left, and is ordered row-first.

The byte array will contain one byte for every pixel, representing the selectedness. 0 is totally unselected, 255 is fully selected.

You can read outside the Selection's boundaries; those pixels will be unselected.

The byte array is a copy of the original selection data.

Parameters
xx position from where to start reading
yy position from where to start reading
wrow length to read
hnumber of rows to read
Returns
a QByteArray with the pixel data. The byte array may be empty.

Definition at line 298 of file Selection.cpp.

void Selection::resize ( int w,
int h )
slot

Resize the selection to the given width and height.

The top-left position will not be moved.

Definition at line 249 of file Selection.cpp.

◆ select

void Selection::select ( int x,
int y,
int w,
int h,
int value )

Select the given area.

The value can be between 0 and 255; 0 is totally unselected, 255 is totally selected.

Definition at line 255 of file Selection.cpp.

◆ selectAll

void Selection::selectAll ( Node * node,
int value )
slot

Select all pixels in the given node.

The value can be between 0 and 255; 0 is totally unselected, 255 is totally selected.

◆ setPixelData

void Selection::setPixelData ( QByteArray value,
int x,
int y,
int w,
int h )
slot

setPixelData writes the given bytes, of which there must be enough, into the Selection.

Parameters
valuethe byte array representing the pixels. There must be enough bytes available. Krita will take the raw pointer from the QByteArray and start reading, not stopping before (w * h) bytes are read.

ythe y position to start writing from
wthe width of each row
hthe number of rows to write

Definition at line 310 of file Selection.cpp.
