Detailed Description

Class implementing a dump device in SVG.

Library: svgcore

The class IlvSVGDevice inherits from IlvPort and provides exporting services using the SVG format. It allows to export any region of a view into a text file. All the drawing member functions are implemented to generate the corresponding SVG code instead of drawing to a window or bitmap.

Member Enumeration Documentation

◆ StyleMode

enum IlvSVGDevice::StyleMode

Values to specify the style exporting mode.

Enumerator
Inline	Export to the 'style' attribute to specify the style rules directly on a given element.
Class	Export all styles to <style> SVG element. Use the 'class' attribute to specify the style class for a given element

Constructor & Destructor Documentation

◆ IlvSVGDevice()

IlvSVGDevice::IlvSVGDevice ( IlvDisplay * display )

Constructor.

Initializes a new instance of IlvSVGDevice.

Parameters

display The display instance.

Member Function Documentation

◆ clip() [1/2]

void IlvSVGDevice::clip ( const IlvRect * rect ) const

overridevirtual

Limits the drawing to the given rectangular area.

Limits the drawing to the rect area. This area maps out a temporary clipping area. These settings will be erased when a new clip function is called.

Parameters

rect	The drawing rectangle.

Implements IlvPort.

◆ clip() [2/2]

void IlvSVGDevice::clip ( const IlvRegion * region ) const

overridevirtual

Limits the drawing to the given region.

Limits the drawing to the region region. This area maps out a temporary clipping area. These settings will be erased when a new clip function is called.

Parameters

region The drawing region.

Implements IlvPort.

◆ drawArc()

void IlvSVGDevice::drawArc	(	const IlvPalette *	palette,
		const IlvRect &	rect,
		IlFloat	start,
		IlFloat	range
	)		const

overridevirtual

Draws an arc.

Draws an arc that is part of an ellipse whose bounding box is the rectangle specified by rect. The arc extends from the angle start to the angle formed by the sum of start and range. These angles are given in degrees and the arc is drawn counterclockwise for positive angles and clockwise for negative angles. Palette's border position doesn't affect the draw. Palette's line width is drawn centered on bounds. LIMITATION: In corner cases, Arc beginning and end might not be precise.

Parameters

palette	The palette to use for the color of the arc.
rect	The bounding box of the ellipse for the arc.
start	The start angle in degrees.
range	The range in degrees.

Implements IlvPort.

◆ drawBezier()

void IlvSVGDevice::drawBezier	(	const IlvPalette *	palette,
		IlUInt	count,
		const IlvPoint *	points
	)		const

overridevirtual

Draws a set of Bézier curves.

Draws a set of Bézier curves. The points parameter is a pointer to count points defining the curve. Each fragment of a Bézier curve is represented by four points. The first point indicates where the curve starts, and the fourth point indicates where it ends. The second and third points determine the orientation of the curve. Here is a simple example, with a single fragment:

Principle of the Bézier curves

The first point in the points array starts the curve. The next two points are control points, which determine the shape of the curve. The fourth point is both the last point of the first curve fragment and the starting point - if it exists - of the next fragment.

Parameters

palette	The palette used for drawing.
count	The number of points defining the curve.
points	The array of count points defining the curve.

Reimplemented from IlvPort.

◆ drawBitmap() [1/2]

		IlBoolean	transparent = `IlFalse`
	)		const

overridevirtual

Draws an image.

Draws the image stored in src in the rectangle from, using the alignment position specified in the alignment parameter in relation to from. Copies part of the image maintained by a source port called src to this destination port.

		IlvPosition	align = `IlvLeft`
	)		const

overridevirtual

Draws a string at the given position.

Draws a string at the position referred to as position. The text to be drawn is given in the string parameter and its length is set in the length integer parameter. For this length parameter you can provide a negative number -1 instead of giving the real length. Text length is then computed internally since string is handled as a zero-terminated character array. The align parameter indicates how the string is to be aligned with respect to the position point. For this alignment, the y-coordinate of the position point represents the baseline, and the options are IlvLeft, IlvRight, and IlvCenter.

Parameters

palette	The palette used for drawing the string.
position	The location where to draw the string. This indicates the y location of the base line, and the x coordinates depends on align.
string	The text to draw.

	)

overridevirtual

Draws a transformed string.

Similar to drawString except that the string is drawn using the transformer t. Note that with the X window system, you should use normal fonts and transform the fonts through bitmaps. With Windows and OS/2, you should use true system vectorial fonts such as truetype fonts.

Parameters

palette	The palette used to draw the string.
string	The text to draw.
length	The length of the string.
t	The transformer to apply to the string.
clip	The destination clip area.

		const IlvRect &	rect,
		IlFloat	start,
		IlFloat	range
	)		const

overridevirtual

Fills the arc.

Fills the closed arc that is part of an ellipse whose bounding box is the rectangle specified by rect. The arc extends from the angle start to the angle formed by the sum of start and range. These angles are given in degrees. The actual filled shape depends on how the arc has been closed, either in IlvArcPie mode or in IlvArcChord mode. Palette's line width doesn't affect the drawing.

Parameters

palette	The palette to use for the fill color of the arc.
rect	The bounding box of the ellipse for the arc.
start	The start angle in degrees.
range	The range in degrees.

Implements IlvPort.

◆ fillBezier()

void IlvSVGDevice::fillBezier	(	const IlvPalette *	palette,
		IlUInt	count,
		const IlvPoint *	points
	)		const

overridevirtual

Fills an area specified by a set of Bézier curves.

Parameters

palette	The palette used for drawing.
count	The number of points defining the curve.
points	The array of count points defining the curve.

Reimplemented from IlvPort.

◆ fillPaths()

void IlvSVGDevice::fillPaths	(	const IlvPalette *	palette,
		IlUInt	count,
		const IlvPointArray *	pathArray
	)		const

overridevirtual

Fills the shape defined by the given paths.

Fills the shape defined by all the paths described in the IlvPointArray array pathArray, with the IlvPalette palette. If count is 1, fillPaths may be seen as the drawing of a polygon. If none of the paths provided intersect, each polygon is drawn with the palette. The drawing becomes more complex when the paths intersect. A simple way to see this drawing is that when filled areas overlap, the intersection is empty. When a third area intersects with the first two areas, the intersection is filled.

The two objects have no filled intersection.

The small gray area in the middle represents the filled intersection of these three objects, while the white spaces are the overlapping areas between two objects. (For the purpose of this diagram, rectangles have been outlined).

Parameters

palette	The palette to use for the fill color of the paths.
count	The number of paths provided in the `IlvPointArray` array.
pathArray	The array of paths.

Reimplemented from IlvPort.

	)		const

overridevirtual

Fills a polygon.

Fills a polygon that is drawn as a series of connected lines between the set of count points referred to as points.
If the optional flag convex is set to IlTrue, drawing convex polygons on certain systems may be accelerated. This feature should only be used when you are sure that the points provided form a convex contour. If this is not the case the result may be unpredictable.

Parameters

palette	The palette to use for the fill color of the polygon.
count	The number of points.
points	The points in the polyline.
convex	Flag for convex polygons.

void IlvSVGDevice::stretchBitmap	(	const IlvPalette *	palette,
		const IlvPoint &	to,
		const IlvBitmap *	src,
		const IlvTransformer &	t,
		const IlvRect *	clip = `0`
	)		const

overridevirtual

Stretches a bitmap.

Draws the bitmap src in the point to, applying the transformation t. (In a Windows environment, you can only zoom in on the object, you cannot rotate.) The result is displayed in the current object.

Parameters

palette	The palette used for drawing.
to	The point to stretch the bitmap to.
src	The bitmap to stretch.
t	The transformation to apply to the bitmap.
clip	The destination clip area.

Implements IlvPort.

◆ stretchBitmap() [2/2]

void IlvSVGDevice::stretchBitmap	(	const IlvPalette *	palette,
		const IlvRect &	from,
		const IlvBitmap *	src,
		const IlvRect *	clip = `0`
	)		const

overridevirtual

Stretches a bitmap.

Stretches the dimensions from in the bitmap src to correspond with the size of this IlvPort object. The result is displayed in the current port with the palette palette, and clipped by the parameter clip.

Parameters

palette	The palette used for drawing.
from	The location of the source area.
src	The bitmap to stretch.
clip	The destination clip rectangle.

Implements IlvPort.

◆ stretchBitmapData()

void IlvSVGDevice::stretchBitmapData	(	const IlvPalette *	palette,
		const IlvBitmapData *	src,
		const IlvRect &	from,
		const IlvRect &	to,
		IlBoolean	opaque = `IlFalse`
	)		const

overridevirtual

Draws a bitmap data.

This method allows bitmap datas to be drawn. If the bitmap data has per pixel alpha, then it is composed with the underlying graphics.

Parameters

palette	The palette used for drawing.
src	The bitmap data to draw.
from	The source rectangle in the bitmap data.
to	The destination rectangle.
opaque	A Boolean value indicating whether per pixel alpha should be taken into account (`IlTrue` indicates that no per pixel alpha is used).

Implements IlvPort.

◆ stretchTransparentBitmap() [1/2]

void IlvSVGDevice::stretchTransparentBitmap	(	const IlvPalette *	palette,
		const IlvPoint &	to,
		const IlvBitmap *	src,
		const IlvTransformer &	t,
		const IlvRect *	clip = `0`
	)		const

overridevirtual

Stretches a transparent bitmap.

Stretches the transparent bitmap src to the point to, applying the transformation t. The result is displayed in the current object.

Parameters

palette	The palette used for drawing.
to	The point to stretch the bitmap to.
src	The transparent bitmap to stretch.
t	The transformation to apply to the bitmap.
clip	The destination clip area.

Implements IlvPort.

◆ stretchTransparentBitmap() [2/2]

void IlvSVGDevice::stretchTransparentBitmap	(	const IlvPalette *	palette,
		const IlvRect &	from,
		const IlvBitmap *	src,
		const IlvRect *	clip = `0`
	)		const

overridevirtual

Stretches a transparent bitmap.

Stretches the source bitmap src in the rectangle from. The result is displayed in the bitmap src with the palette palette and clipped by parameter clip.

Parameters

palette	The palette used for drawing.
from	The location of the source area.
src	The transparent bitmap to stretch.
clip	The destination clip rectangle.
