Member Function Documentation

colorspace_t Reader::colorspace (  )  [pure virtual]

Get colorspace from the just read image.

Returns:
colorspace

Implemented in FvRawReader, JpegReader, PNGReader, and PNMReader.

unsigned int Reader::pixel_height (  )  [pure virtual]

Get height of read image in pixels.

Returns:
height of image

Implemented in FvRawReader, JpegReader, PNGReader, and PNMReader.

unsigned int Reader::pixel_width (  )  [pure virtual]

Get width of read image in pixels.

Returns:
width of image

Implemented in FvRawReader, JpegReader, PNGReader, and PNMReader.

void Reader::read (  )  [pure virtual]

Read data from file.

Implemented in FvRawReader, JpegReader, PNGReader, and PNMReader.

void Reader::set_buffer ( unsigned char *  yuv422planar_buffer  )  [pure virtual]

Set buffer that the read image should be written to.

Parameters:
yuv422planar_buffer buffer to write image to. The reader must ensure that it does the proper conversion (if needed) to YUV 422 planar format.
