Detailed Description

The Q3Picture class is a paint device that records and replays Q3Painter commands.

Q3Picture can also read and write SVG (Scalable Vector Graphics) files; these files are in an XML format specified by http://www.w3.org/Graphics/SVG/ W3C. Note that when using the load() and save() functions to read and write SVG files, the format must be specified.

Q3Picture::Q3Picture ()

Constructs a Q3Picture.

Q3Picture::Q3Picture ( const QPicture & other )

Constructs a copy of other.

bool Q3Picture::load ( QIODevice * device, const char * format = 0 )

Loads the picture in the specified format from the given device. Returns true if the file is loaded successfully; otherwise returns false.

Note that when using the load() function to read SVG files, the format must be specified. For example:

 picture.load("drawing.svg", SVG);

See also save().

bool Q3Picture::load ( const QString & fileName, const char * format = 0 )

This is an overloaded member function, provided for convenience.

Loads the picture in the specified format from a file with the given fileName. Returns true if the file is loaded successfully; otherwise returns false.

bool Q3Picture::save ( QIODevice * device, const char * format = 0 )

Saves the picture in the specified format to the given device.

Note that when using the save() function to save SVG files, the format must be specified. For example:

 Q3Picture picture;
 QPainter painter;
 painter.begin(&picture);           // paint in picture
 ...
 painter.end();                     // painting done
 picture.save("drawing.svg", SVG);  // save picture

See also load().

bool Q3Picture::save ( const QString & fileName, const char * format = 0 )

This is an overloaded member function, provided for convenience.

Saves the picture in the specified format to the file with the given fileName.
