Member Function Documentation

fillGrayscale()

virtual void pcl::io::Image::fillGrayscale	(	unsigned	width,
		unsigned	height,
		unsigned char *	gray_buffer,
		unsigned	gray_line_step = `0`
	)		const

pure virtual

fills a user given buffer with the gray values, with an optional nearest-neighbor down sampling and an optional subregion

Parameters

[in]	width	desired width of output image.
[in]	height	desired height of output image.
[in,out]	gray_buffer	the output gray buffer.
[in]	gray_line_step	optional line step in bytes to allow the output in a rectangular subregion of the output buffer.

Implemented in pcl::io::ImageRGB24, and pcl::io::ImageYUV422.

fillRaw()

virtual void pcl::io::Image::fillRaw ( unsigned char * rgb_buffer ) const

inlinevirtual

fills a user given buffer with the raw values.

Parameters

[in,out] rgb_buffer

Definition at line 121 of file image.h.

fillRGB()

virtual void pcl::io::Image::fillRGB	(	unsigned	width,
		unsigned	height,
		unsigned char *	rgb_buffer,
		unsigned	rgb_line_step = `0`
	)		const

pure virtual

fills a user given buffer with the RGB values, with an optional nearest-neighbor down sampling and an optional subregion

Parameters

[in]	width	desired width of output image.
[in]	height	desired height of output image.
[in,out]	rgb_buffer	the output RGB buffer.
[in]	rgb_line_step	optional line step in bytes to allow the output in a rectangular subregion of the output buffer.

Implemented in pcl::io::ImageRGB24, and pcl::io::ImageYUV422.

getData()

const void* pcl::io::Image::getData ( )

inline

Definition at line 188 of file image.h.

getDataSize()

int pcl::io::Image::getDataSize ( ) const

inline

Definition at line 195 of file image.h.

getEncoding()

virtual Encoding pcl::io::Image::getEncoding ( ) const

pure virtual

returns the encoding of the native data.

Returns: encoding

Implemented in pcl::io::ImageRGB24, and pcl::io::ImageYUV422.

getFrameID()

unsigned pcl::io::Image::getFrameID ( ) const

inline

Returns: frame id of the image.

Note: frame ids are ascending, but not necessarily synchronized with other streams

Definition at line 160 of file image.h.

getHeight()

unsigned pcl::io::Image::getHeight ( ) const

inline

Returns: height of the image

Definition at line 150 of file image.h.

getStep()

unsigned pcl::io::Image::getStep ( ) const

inline

Definition at line 202 of file image.h.

getSystemTimestamp()

Timestamp pcl::io::Image::getSystemTimestamp ( ) const

inline

Returns: the timestamp of the image

Note: the time value is synchronized with the system time.

Definition at line 181 of file image.h.

getTimestamp()

std::uint64_t pcl::io::Image::getTimestamp ( ) const

inline

Returns: the timestamp of the image

Note: the time value is not synchronized with the system time

Definition at line 170 of file image.h.

getWidth()

unsigned pcl::io::Image::getWidth ( ) const

inline

Returns: width of the image

Definition at line 141 of file image.h.

isResizingSupported()

virtual bool pcl::io::Image::isResizingSupported	(	unsigned	input_width,
		unsigned	input_height,
		unsigned	output_width,
		unsigned	output_height
	)		const

pure virtual

Parameters

[in]	input_width	width of input image
[in]	input_height	height of input image
[in]	output_width	width of desired output image
[in]	output_height	height of desired output image

Returns: whether the resizing is supported or not.

Implemented in pcl::io::ImageRGB24, and pcl::io::ImageYUV422.
