Member Function Documentation

getCount()

unsigned long DiMonoOutputPixel::getCount ( ) const

inline

get number of pixel per frame

Returns

number of pixel per frame

Referenced by DiMonoOutputPixelTemplate< T1, T2, T3 >::overlay().

getData()

virtual const void* DiMonoOutputPixel::getData ( ) const

pure virtual

get pointer to output pixel data (abstract)

Returns

pointer to pixel data

Implemented in DiMonoOutputPixelTemplate< T1, T2, T3 >.

Referenced by DiMonoOutputPixelTemplate< T1, T2, T3 >::getData().

getDataPtr()

virtual void* DiMonoOutputPixel::getDataPtr ( )

pure virtual

get pointer to output pixel data (abstract)

Returns

pointer to pixel data

Implemented in DiMonoOutputPixelTemplate< T1, T2, T3 >.

Referenced by DiMonoOutputPixelTemplate< T1, T2, T3 >::getDataPtr().

getItemSize()

virtual size_t DiMonoOutputPixel::getItemSize ( ) const

pure virtual

get size of one pixel / item in the pixel array (abstract)

Returns

item size

Implemented in DiMonoOutputPixelTemplate< T1, T2, T3 >.

Referenced by DiMonoOutputPixelTemplate< T1, T2, T3 >::getItemSize().

getRepresentation()

virtual EP_Representation DiMonoOutputPixel::getRepresentation ( ) const

pure virtual

get integer representation (abstract)

Returns

integer representation

Implemented in DiMonoOutputPixelTemplate< T1, T2, T3 >.

isUnused()

int DiMonoOutputPixel::isUnused

(

const unsigned long

value

)

check whether specified pixel value is used in the image.

Pixel array is examined when this method is called for the first time (just-in-time creation / create on demand of the supporting table).

Parameters

value

pixel value to be checked

Returns

true if value is used, false otherwise

writePPM() [1/2]

virtual int DiMonoOutputPixel::writePPM ( STD_NAMESPACE ostream &  stream ) const

pure virtual

write pixel data of selected frame to PPM/ASCII file (abstract)

Parameters

stream

open C++ output stream

Returns

status, true if successful, false otherwise

Implemented in DiMonoOutputPixelTemplate< T1, T2, T3 >.

writePPM() [2/2]

virtual int DiMonoOutputPixel::writePPM ( FILE *  stream ) const

pure virtual

write pixel data of selected frame to PPM/ASCII file (abstract)

Parameters

stream

open C file stream

Returns

status, true if successful, false otherwise

Implemented in DiMonoOutputPixelTemplate< T1, T2, T3 >.
