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
