Member Function Documentation

bool libmwaw_applepict1::OpCode::computeSize	(	MWAWInputStream &	input,
		int &	sz
	)		const `[inline]`

computes the size of the data

Referenced by libmwaw_applepict1::PictParser::convertToPict2().

static int libmwaw_applepict1::OpCode::getSize	(	MWAWInputStream &	input,
		DataType	type
	)		`[inline, static, protected]`

returns the size of the next argument of type type.

Note:: This function can update the next reading position in the input, if it uses the input to compute the size of this argument

static bool libmwaw_applepict1::OpCode::readCColor	(	MWAWInputStream &	input,
		DataType	type,
		MWAWColor &	col
	)		`[inline, static, protected]`

low level: reads a color argument (version 2)

Note:: check if this is not an indexed color

Referenced by readValue().

Referenced by readValue().

bool libmwaw_applepict1::OpCode::readData	(	MWAWInputStream &	input,

static bool libmwaw_applepict1::OpCode::readPattern	(	MWAWInputStream &	input,
		DataType	type,
		int(&)	pat[8]
	)		`[inline, static, protected]`

low level: reads a pattern argument

static bool libmwaw_applepict1::OpCode::readPoint	(	MWAWInputStream &	input,
		DataType	type,
		MWAWVec2i &	res
	)		`[inline, static, protected]`

low level: reads a point argument

Referenced by readPoly(), readRect(), and readValue().

static bool libmwaw_applepict1::OpCode::readPoly	(	MWAWInputStream &	input,
		DataType	type,
		MWAWBox2i &	box,
