Member Function Documentation

std::string JpegParser::getComments (  )  const [virtual]

Get the comments from the image without fully reading it.

Implements RasterParser.

Definition at line 271 of file JpegParser.C.

GenericFrame JpegParser::getFrame (  )  [virtual]

Get a GenericFrame representation from the raster file.

This can subsequently be converted to rgb, grayscale, floating-point, or video-yuv.

Implements RasterParser.

GenericFrameSpec JpegParser::getFrameSpec (  )  const [virtual]

Get the specifications of the image without fully reading it.

Implements RasterParser.

Definition at line 245 of file JpegParser.C.

References ASSERT, Image< T >::getDims(), GenericFrame::GRAY_U8, Image< T >::initialized(), and GenericFrame::RGB_U8.

bool JpegParser::getTag ( uint  tag,
std::string name,
std::string value 
) const [virtual]

Get image tags if the image supports them.

Implements RasterParser.

Definition at line 285 of file JpegParser.C.

uint JpegParser::getTagCount (  )  const [virtual]

Get image tags if the image supports them.

Implements RasterParser.
