/** TextSimplePortionPrimitive2D class
|
|
|
|
This is the basic primitive for representing a text portion. It contains
|
|
all needed information. If it is not handled by a renderer, its decomposition
|
|
will provide the text PolyPolygon outlines as filled polygons, correctly
|
|
transformed.
|
|
|
|
To get better text quality, it is suggested to handle tis primitive directly
|
|
in a renderer. In that case, e.g. hintings on the system can be supported.
|
|
|
|
@param maTextTransform
|
|
The text transformation contains the text start position (always baselined)
|
|
as translation, the FontSize as scale (where width relative to height defines
|
|
font scaling and width == height means no font scaling) and the font rotation
|
|
and shear.
|
|
When shear is used and a renderer does not support it, it may be better to use
|
|
the decomposition which will do everything correctly. Same is true for mirroring
|
|
which would be expressed as negative scalings.
|
|
|
|
@param rText
|
|
The text to be used. Only a part may be used, but a bigger part of the string
|
|
may be necessary for correct layouting (e.g. international)
|
|
|
|
@param aTextPosition
|
|
The index to the first character to use from rText
|
|
|
|
@param aTextLength
|
|
The number of characters to use from rText
|
|
|
|
@param rDXArray
|
|
The distances between the characters. This parameter may be empty, in that case
|
|
the renderer is responsible to do something useful. If it is given, it has to be of
|
|
the size aTextLength. Its values are in logical coordinates and describe the
|
|
distance for each character to use. This is independent from the font width which
|
|
is given with maTextTransform. The first value is the offset to use from the start
|
|
point in FontCoordinateSystem X-Direction (given by maTextTransform) to the start
|
|
point of the second character
|
|
|
|
@param rFontAttribute
|
|
The font definition
|
|
|
|
@param rLocale
|
|
The locale to use
|
|
|
|
@param rFontColor
|
|
The font color to use
|
|
|
|
@param bFilled
|
|
|
|
@param nWidthToFill
|
|
|
|
@param rFillColor
|
|
Text background color (has nothing to do with bFilled and nWidthToFill)
