Detailed Description

class to store small data which are potentially a picture

Constructor & Destructor Documentation

MWAWPictDUnknown::MWAWPictDUnknown ( )
inlineprotected

protected constructor: uses check to construct a picture

Member Function Documentation

MWAWPictDUnknown::ReadResult MWAWPictDUnknown::checkOrGet ( MWAWInputStreamPtr  input,
int  size,
MWAWPictData **  result = 0L 
)
staticprotected

checks if the data pointed by input and of given size is a pict

  • if not returns MWAW_R_BAD
  • if true
    • set empty to true if the picture contains no data
    • creates a picture if result is given and if the picture is not empty
