Member Function Documentation

fillGrayscale()

void pcl::io::ImageRGB24::fillGrayscale ( unsigned width,
unsigned height,
unsigned char * gray_buffer,
unsigned gray_line_step = 0
) const
overridevirtual

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.

Implements pcl::io::Image.

fillRGB()

void pcl::io::ImageRGB24::fillRGB ( unsigned width,
unsigned height,
unsigned char * rgb_buffer,
unsigned rgb_line_step = 0
) const
overridevirtual

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.

Implements pcl::io::Image.

getEncoding()

Encoding pcl::io::ImageRGB24::getEncoding ( ) const
inlineoverridevirtual

returns the encoding of the native data.

Returns
encoding

Implements pcl::io::Image.

isResizingSupported()

bool pcl::io::ImageRGB24::isResizingSupported ( unsigned input_width,
unsigned input_height,
unsigned output_width,
unsigned output_height
) const
overridevirtual
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.

Implements pcl::io::Image.
