MWAWPictDUnknown::~MWAWPictDUnknown | ( |  | ) |
| final

destructor

## ◆ MWAWPictDUnknown()

MWAWPictDUnknown::MWAWPictDUnknown | ( |  | ) |

protected constructor: uses check to construct a picture

## Member Function Documentation

## ◆ checkOrGet()

MWAWPictDUnknown::ReadResult MWAWPictDUnknown::checkOrGet | ( | MWAWInputStreamPtr | input,
|  | int | size,
|  | MWAWPictData ** | result = `nullptr`
| ) |  |
| 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

Referenced by MWAWPictData::checkOrGet().

## ◆ cmp()

int MWAWPictDUnknown::cmp | ( | MWAWPict const & | a | ) | const
| inlinefinalvirtual

a virtual function used to obtain a strict order, must be redefined in the subs class

Reimplemented from MWAWPictData.

## ◆ getSubType()

SubType MWAWPictDUnknown::getSubType | ( |  | ) | const
| inlinefinalvirtual

returns the picture subtype

Implements MWAWPictData.

## ◆ valid()

bool MWAWPictDUnknown::valid | ( |  | ) | const
| inlinefinalvirtual

returns true if the picture is valid

Reimplemented from MWAWPictData.
