NAME

       PSBrush, PSColor, PSFont, PSPattern - graphics state objects with added PostScript information

SYNOPSIS

       #include <Unidraw/Graphic/pspaint.h>

DESCRIPTION

       PSBrush,  PSColor, PSFont, and PSPattern are subclasses of Brush, Color, Font, and Pattern, respectively,
       that store added information  needed  to  generate  idraw-compatible  PostScript.   Unidraw's  structured
       graphics objects use these subclasses exclusively.

PSBRUSH PUBLIC OPERATIONS

       PSBrush()
       PSBrush(int pattern, int width)
              Create  an  undefined  PSBrush  (the  parameterless  constructor) or one having the specified line
              pattern and width.  Structured graphics having an undefined brush will not  render  their  stroked
              portions.

       int GetLinePattern()
       int Width()
              Return constructor-specified brush parameters.

       boolean None()
              Return true if this is an undefined brush.

       const int* GetDashPattern()
       int GetDashPatternSize()
       int GetDashOffset()
              Return  values  required  to characterize the brush in PostScript.  The equivalent PostScript dash
              pattern is computed from the brush's line pattern.

PSBRUSH PROTECTED OPERATIONS

       void CalcDashPat(int)
              Compute the equivalent PostScript dash pattern from the line pattern specified in the constructor.

PSCOLOR PUBLIC OPERATIONS

       PSColor(
           Color_Intensity, Color_Intensity, Color_Intensity,
           const char* name
       )
              Create a PSColor, supplying  color  intensity  information  and  a  name  to  associate  with  the
              intensities.  The name is used solely to generate idraw-compatible PostScript.

PSFONT PUBLIC OPERATIONS

       PSFont(
           const char* name, const char* PS_name, const char* PS_size
       )
              Construct  a  PSFont,  supplying  the  window-system-specified  font  name  and  the corresponding
              PostScript font name and its size.

       const char* GetName()
       const char* GetPrintFont()
       const char* GetPrintSize()
       const char* GetPrintFontAndSize()
              Return constructor-supplied parameters.  GetPrintFontAndSize  returns  the  concatenation  of  the
              PostScript font name and its size, with a space interposed for legibility.

       int GetLineHt()
              Return an integer version of the PostScript font's size (as supplied to the constructor).

PSPATTERN PUBLIC OPERATIONS

       PSPattern()
       PSPattern(int dither, float graylevel)
       PSPattern(const int* pattern, int)
              Create  an  undefined PSPattern (the parameterless constructor), or one having specific dither and
              graylevel values, or one that replicates  a  pattern  defined  by  the  given  array.   Structured
              graphics having an undefined pattern will not render their filled portions.

       boolean None()
              Return true if this is an undefined pattern.

       float GetGrayLevel()
              Return the graylevel that the pattern approximates, if one was specified in the constructor.

       const int* GetData()
       int GetSize()
              Return  the array that defines the replicated pattern and its size, if the pattern was constructed
              with one.
