Detailed Description

Function Documentation

Pixel() [1/2]

RGBA pcl::Bitmap::Pixel ( const pcl::Point &  p ) const

inline

Returns the value of a bitmap pixel.

Parameters

p	A Point object whose coordinates identify the pixel to read. Pixel coordinates can vary in the range from (0,0) to (Width()-1, Height()-1).

Definition at line 581 of file Bitmap.h.

Pixel() [2/2]

RGBA pcl::Bitmap::Pixel	(	int	x,
		int	y
	)		const

Returns the value of a bitmap pixel.

Parameters

x,y	Bitmap coordinates of the pixel to read. Pixel coordinates can vary in the range from (0,0) to (Width()-1, Height()-1).

ScanLine() [1/2]

RGBA* pcl::Bitmap::ScanLine

(

int

y

)

Returns the starting address of a row of pixels in this bitmap.

Parameters

y	Vertical coordinate of the row of pixels. Vertical coordinates can vary in the range from 0 to Height()-1.

The returned address can be used to modify pixel values.

ScanLine() [2/2]

const RGBA* pcl::Bitmap::ScanLine

(

int

y

)

const

Returns the (constant) starting address of a row of pixels in this bitmap.

Parameters

y	Vertical coordinate of the row of pixels. Vertical coordinates can vary in the range from 0 to Height()-1.

SetPixel() [1/2]

void pcl::Bitmap::SetPixel ( const pcl::Point &  p, RGBA  v  )

inline

Sets the value of a bitmap pixel.

Parameters

p	A Point object whose coordinates identify the pixel to write. Pixel coordinates can vary in the range from (0,0) to (Width()-1, Height()-1).
v	32-bit pixel value encoded in the AARRGGBB format: AA is the alpha (transparency) value, RR is the red component, GG is green and BB is blue. Each element is an 8-bit value.

Definition at line 613 of file Bitmap.h.

SetPixel() [2/2]

void pcl::Bitmap::SetPixel	(	int	x,
		int	y,
		RGBA	v
	)

Sets the value of a bitmap pixel.

Parameters

x,y	Bitmap coordinates of the pixel to write. Pixel coordinates can vary in the range from (0,0) to (Width()-1, Height()-1).
v	32-bit pixel value encoded in the AARRGGBB format: AA is the alpha (transparency) value, RR is the red component, GG is green and BB is blue. Each element is an 8-bit value.
