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.
