Detailed Description

Base Class for all kinds of images

Member Typedef Documentation

◆ vCtor

typedef coImageImpl * covise::coImage::vCtor(const char *filename)

type for virtual constructor creating from a file name

Constructor & Destructor Documentation

◆ coImage() [1/3]

coImage::coImage ( const char * filename )

Constructor: build from filename.

◆ coImage() [2/3]

coImage::coImage ( coBinImage * binImage )

◆ coImage() [3/3]

covise::coImage::coImage ( )

inline

Default c'tor: does nothing.

◆ ~coImage()

coImage::~coImage ( )

Destructor: build from filename.

Member Function Documentation

◆ errorMessage()

const char * coImage::errorMessage ( )

Error message if problems occurred: empty if ok.

◆ getBitmap()

const unsigned char * coImage::getBitmap ( int frameno = 0 )

get pointer to internal data

◆ getHeight()

int coImage::getHeight ( )

height of image;

◆ getNumChannels()

int coImage::getNumChannels ( )

get number of Color Channels

◆ getNumFrames()

int coImage::getNumFrames ( )

get number of frames

◆ getWidth()

int coImage::getWidth ( )

width of image

◆ isBad()

bool coImage::isBad ( )

Did we have errors on reading.

◆ registerImageType()

bool coImage::registerImageType	(	const char *	suffixes[],
		coImage::vCtor *	cTor
	)

static

register a derived class for usage with the Factory

◆ scale()

void COIMAGEEXPORT coImage::scale	(	int	newWidth,
		int	newHeight
	)

create a scaled image: implemented, can be overridden by subclasses @@@ currently only shrink

To scale an image, we create a new coBinImage instead of the current image and attach it to our image_ variable

Line-by-line calculations of result image

◆ scaleExp2()

void coImage::scaleExp2 ( )

scale to next lower 2^x in both dimensions

Member Data Documentation

◆ image_

coImageImpl* covise::coImage::image_

private

the real internal image

◆ vCtorList_

map< string, coImage::vCtor * > * coImage::vCtorList_ = NULL

staticprivate

virtual c'tors for given file endings
