Detailed Description

These helper classes are used to support two-level operator [].

Provides an accessor for reading or writing the contents of one row of the image in-place.

◆ __setitem__()

__setitem__ ( int  x,
const LColorf  v 
)

Set the pixel at the given column in the row. If the image has no alpha channel, the alpha component is ignored.

◆ getAlphaVal()

Xelval getAlphaVal ( int  x)

Fetch the alpha value at the given column in the row.

◆ getXelVal()

Xel getXelVal ( int  x)

Fetch the pixel at the given column in the row.

◆ operator[]() [1/9]

operator[] ( int  i,
float  assign_val 
)

◆ operator[]() [2/9]

float operator[] ( int  i)

◆ operator[]() [3/9]

operator[] ( int  i,

setXelVal ( int  x,
const Xel  v 
)

Set the pixel at the given column in the row.

◆ size() [1/5]

static int size ( )
static

Returns 3: the number of columns of a LMatrix3.

◆ size() [2/5]
