## createAWTBitmap()

virtual unsigned long DiColorPixel::createAWTBitmap | ( | void *& | data,
|  | const Uint16 | width,
|  | const Uint16 | height,
|  | const unsigned long | frame,
|  | const int | fromBits,
|  | const int | toBits ) const

pure virtual

create true color (32 bit) bitmap for Java (AWT default format).

Parameters

  data | resulting pointer to bitmap data (set to NULL if an error occurred)
  width | number of columns of the image
  height | number of rows of the image
  frame | index of frame to be converted (starting from 0)
  fromBits | number of bits per sample used for internal representation of the image
  toBits | number of bits per sample used for the output bitmap (<= 8)

Returns
  number of bytes allocated by the bitmap, or 0 if an error occurred

Implemented in DiColorPixelTemplate< T >, DiColorPixelTemplate< T2 >, and DiColorPixelTemplate< T3 >.

## createDIB()

virtual unsigned long DiColorPixel::createDIB | ( | void *& | data,
|  | const unsigned long | size,
|  | const Uint16 | width,
|  | const Uint16 | height,
|  | const unsigned long | frame,
|  | const int | fromBits,
|  | const int | toBits,
|  | const int | mode,
|  | const int | upsideDown,
|  | const int | padding ) const

pure virtual

create true color (24/32 bit) bitmap for MS Windows.

Parameters

  data | untyped pointer memory buffer (set to NULL if not allocated externally)
  size | size of the memory buffer in bytes (if 0 'data' is set to NULL)
  width | number of columns of the image
  height | number of rows of the image
  frame | index of frame to be converted (starting from 0)
  fromBits | number of bits per sample used for internal representation of the image
  toBits | number of bits per sample used for the output bitmap (<= 8)
  mode | color output mode (24 or 32 bits, see dcmimgle/dcmimage.h for details)
  upsideDown | specifies the order of lines in the images (0 = top-down, bottom-up otherwise)
  padding | align each line to a 32-bit address if true

Returns
  number of bytes allocated by the bitmap, or 0 if an error occurred

Implemented in DiColorPixelTemplate< T >, DiColorPixelTemplate< T2 >, and DiColorPixelTemplate< T3 >.

## getPixelData()

virtual OFBool DiColorPixel::getPixelData | ( | void * | data,
|  | const unsigned long | count,
|  | const unsigned long | fcount,
|  | const unsigned long | frames,
|  | const int | planar ) const

pure virtual

fill given memory block with pixel data (all three image planes, RGB)

Parameters

  data | pointer to memory block (array of 8 or 16 bit values, OB/OW)
  count | number of T-size entries allocated in the 'data' array
  fcount | number of pixels per frame
  frames | total number of frames present in intermediate representation
  planar | flag indicating whether data shall be stored color-by-pixel or color-by-plane

Returns
  OFTrue if successful, OFFalse otherwise

Implemented in DiColorPixelTemplate< T >, DiColorPixelTemplate< T2 >, and DiColorPixelTemplate< T3 >.

## getPlanarConfiguration()

int DiColorPixel::getPlanarConfiguration | ( |  | ) | const

inline

get planar configuration of the original pixel data

Returns
  planar configuration (0 = color-by-pixel, 1 = color-by-plane)

References PlanarConfiguration.

## getPlanes()

int DiColorPixel::getPlanes | ( |  | ) | const

inline virtual

get number of planes

Returns
  number of planes (here 3, color)

Implements DiPixel.
