The SymbolEditor application was originally written to provide symbol libraries for the KXStitch application. If anyone else finds these symbol libraries useful, these are the file format used. Have a look at the code in the two applications for examples of their usage.
Versions of the format
There are currently two versions of the file format. Version 100 is deprecated and it is unlikely that any symbol libraries will exist in the wild. Version 101 is the current format.
Version 100
Format uses QDataStream::Qt_4_0
file {
char[15] containing 'KXStitchSymbols'
qint32 file_version = 100
qint16 next_symbol_id
QMap<qint16 index, QPainterPath path> pathsMap
}
Version 101
Format uses QDataStream::Qt_4_0
file {
char[15] containing 'KXStitchSymbols'
qint32 file_version = 101
qint16 next_symbol_id
QMap<qint16 index, symbol> symbolMap
}
The index can be used by applications to reference a symbol in a library.
Symbol Definition
The symbol definition only has one version at the moment, version 100, which is defined as
Symbol
{
qint32 version;
QPainterPath path;
bool filled;
qreal lineWidth;
qint32 Qt::PenCapStyle
qint32 Qt::PenJoinStyle
}
The coordinates of the QPainterPath will be in the range 0.0 .. 1.0 in both the x and y directions. The QPainterPath can be scaled to suit the destination. Both SymbolEditor and KXStitch use a transformation matrix on the QWidget to achieve this.
