Detailed Description

Base Class for all kinds of images

Member Typedef Documentation

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

type for virtual constructor creating from a file name

Constructor & Destructor Documentation

coImage::coImage

(

const char *

filename

)

Constructor: build from filename.

coImage::coImage

(

coBinImage *

binImage

)

covise::coImage::coImage ( )

inline

Default c'tor: does nothing.

coImage::~coImage

(

)

Destructor: build from filename.

Member Function Documentation

const char * coImage::errorMessage

(

)

Error message if problems occurred: empty if ok.

const unsigned char * coImage::getBitmap

(

int

frameno = 0

)

get pointer to internal data

int coImage::getHeight

(

)

height of image;

int coImage::getNumChannels

(

)

get number of Color Channels

int coImage::getNumFrames

(

)

get number of frames

int coImage::getWidth

(

)

width of image

bool coImage::isBad

(

)

Did we have errors on reading.

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

static

register a derived class for usage with the Factory

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

void coImage::scaleExp2

(

)

scale to next lower 2^x in both dimensions

Member Data Documentation
