A concrete renderer based on Qt4 for conversion of Symbology Enconding Mark elements to an image pattern. It is a extension that considers marks with well-known name in the format: "ttf://font#code". Here, "font" is the name of a TrueType font and "code" is the character code. The character code can be enconded in hexadecimal, octonal or decimal. e.g.: "ttf://Arial#0x12", "ttf://Times#042", "ttf://Verdana#10". More...

Member Function Documentation

static void te::qt::widgets::GlyphMarkRenderer::decode	(	QString &	name,
		QString &	font,
		QChar &	charCode
	)

static

Decodes the given name extracting the parameters known by this renderer.

Parameters

name	The name dealt by this renderer. e.g. "ttf://Times#0x12".
font	The font name that will be extracted from name.
charCoder	The char code that will be extracted from name.

void te::qt::widgets::GlyphMarkRenderer::draw	(	QImage *	img,
		QPainterPath &	path
	)

protected

Draw the given path on the the given image using the internal pen and brush.

Parameters

img	The image where the path will be drawn.
path	The path that will be drawn.

static QString te::qt::widgets::GlyphMarkRenderer::encode	(	const QString &	font,
		const int &	charCode
	)

static

Encodes the given parameters to a format known by this renderer.

Parameters

font	The font name. e.g. "Times".
charCoder	The decimal char code.

Returns: A string that represents the format known by this renderer. e.g. "ttf://Times#0x12".

Note: The given char code will be enconded in hexadecimal.

void te::qt::widgets::GlyphMarkRenderer::end ( )

protected

Finalizes the internal QPainter resources.

bool te::qt::widgets::GlyphMarkRenderer::getChar	(	QString &	charCode,
		QChar &	ch
	)

protected

Converts the character code to a char.

Parameters

charCode	The character code. It can be enconded in hexadecimal, octonal or decimal.
ch	The result char from character code conversion.

Returns: It returns true if the character code was converted. Otherwise, it returns false.

void te::qt::widgets::GlyphMarkRenderer::getSupportedMarks ( std::vector< std::string > & marks ) const

virtual

Method that informs the set of supported marks by a specific concrete mark renderer.

Parameters

marks A pre-created vector of string that will be filled with the supported marks names.

Implements te::map::AbstractMarkRenderer.

te::color::RGBAColor** te::qt::widgets::GlyphMarkRenderer::render	(	const te::se::Mark *	mark,
		std::size_t	size
	)

virtual

It generates the image pattern from the given Symbology Enconding Mark element.

Parameters

mark	The Symbology Enconding Mark element that will be used to build the image pattern.
size	The size of image pattern that will be generated.

Returns: The RGBA image that represents the mark.

Note: The caller will take the ownership of the returned pointer.

Implements te::map::AbstractMarkRenderer.

void te::qt::widgets::GlyphMarkRenderer::setup ( QImage * img )

protected

Setups the internal QPainter and associates it with the given paint device (QImage).
