GSSetCustomLineMask()

#define GSSetCustomLineMask(m1,m2,m3,m4,m5,m6,m7,m8) \
        GR_SET_CUSTOM_LINE_MASK, (m1), (m2), (m3), (m4), (m5), (m6), (m7), \
(m8)

This GString creation macro specifies a new bitmap to use as the mask when drawing lines. It takes eight arguments, each a byte representing the pixels one one row.

Include: gstring.h

GSSetCustomLineStyle()

#define GSSetCustomLineStyle(index,count) \
        GR_SET_CUSTOM_LINE_STYLE,(index),(count)

This GString creation macro sets a custom style, or "dottedness," to use when drawing lines. It takes two arguments: the first is the index into the pattern to use, the second is the number of dash pairs in the line style. Following this macro should appear a DashPairArray containing the line style's data.

Include: gstring.h

GSSetCustomTextMask()

#define GSSetCustomTextMask(m1,m2,m3,m4,m5,m6,m7,m8) \
        GR_SET_CUSTOM_TEXT_MASK, (m1), (m2), (m3), (m4), (m5), (m6), (m7),
(m8)

This GString creation macro specifies a custom bitmask to use when rendering text. It takes eight arguments, each a byte representing one row of pixel data.

Include: gstring.h

GSSetCustomTextPattern()

#define GSSetCustomTextPattern(pattern,size) \
        GR_SET_CUSTOM_TEXT_PATTERN,GOC_PATTERN(pattern), GOC_WORD(size)

This GString creation macro sets a custom pattern to use when rendering text. It takes two arguments: a GraphicPattern value and the size of the pattern's data. Following this macro should appear the pattern's data.

Include: gstring.h

GSSetDefaultTransformation()

#define GSSetDefaultTransform() \
        GR_SET_DEFAULT_TRANSFORM

This GString creation macro replaces the current coordinate transformation with the default coordinate transformation.

Include: gstring.h

GSSetFont()

#define GSSetFont(id,size_wbf) \
                GR_SET_FONT,GOC_WBF(size_wbf),GOC_WORD(id)

This GString creation macro sets the font to use when rendering text. It takes two arguments: a FontID and a pointsize, expressed as a WBFixed number.

Include: gstring.h

GSSetFontWeight()

#define GSSetFontWeight(weight) GR_SET_FONT_WEIGHT,GOC_WORD(weight)

This GString creation macro sets the FontWeight to use when rendering text.

Include: gstring.h

GSSetFontWidth()

#define GSSetFontWidth(width) GR_SET_FONT_WIDTH,GOC_WORD(width)

This GString creation macro sets the FontWidth to use when rendering text.

Include: gstring.h

GSSetGStringBounds()

#define GSSetGStringBounds(x1_w,y1_w,x2_w,y2_w) \
        GR_SET_GSTRING_BOUNDS,GOC_SW(x1_w),GOC_SW(y1_w), \
GOC_SW(x2_w),GOC_SW(y2_w)

This GString creation macro is useful for optimizations. When drawing your GString , the graphics system will take time to traverse your GString and determine its drawing bounds. If you compute those bounds ahead of time, you may pass them as arguments to this macro--if the graphics system encounters this GString element, it won't bother to traverse the rest of the GString , but will use the pre-computed values. Thus, if you use this GString element, you should place it at the beginning of your GString . The macro takes four word-length arguments, the coordinates of the bounds of the GString .

Include: gstring.h

GSSetLineAttr()

#define GSSetLineAttr(r,g,b,mode,mask,width,end,join,style) \
        GR_SET_LINE_ATTR,(CF_RGB),(r),(g),(b),(mask),(mode),(end),(join), \
(style) ,GOC_WWF(width)

This GString creation macro sets the LineAttr to use when drawing lines. It takes several arguments: the red, green, and blue components of the color to use; the ColorMapMode to use when trying to draw in an unavailable color, the drawing mask to use, the width, the LineEnd , the LineJoin , and the LineStyle .

Include: gstring.h

GSSetLineColor()

#define GSSetLineColor(r,g,b) GR_SET_LINE_COLOR,(r),(g),(b)

This GString creation macro sets the line-drawing color in terms of its red, green, and blue components.

Include: gstring.h

GSSetLineColorIndex()

#define GSSetLineColorIndex(color) GR_SET_LINE_COLOR_INDEX, (color)

This GString creation macro sets the line-drawing color by specifying which entry in the palette to use.

Include: gstring.h

GSSetLineColorMap()

#define GSSetLineColorMap(mode) GR_SET_LINE_COLOR_MAP,(mode)

This GString creation macro sets the ColorMapMode to use when trying to draw lines with an unavailable color.

Include: gstring.h
