GSSetLineEnd()

#define GSSetLineEnd(end) \
        GR_SET_LINE_END,(end)

This GString creation macro sets the LineEnd value to use when drawing endpoints of lines.

Include: gstring.h

GSSetLineJoin()

#define GSSetLineJoin(join) \
                GR_SET_LINE_JOIN,(join)

This GString creation macro sets the LineJoin value to use when drawing corners in polylines, polygons, and rectangles.

Include: gstring.h

GSSetLineMask()

#define GSSetLineMask(index) GR_SET_LINE_MASK, (index)

This GString creation macro sets the mask to use when drawing lines.

Include: gstring.h

GSSetLineStyle()

#define GSSetLineStyle(style,index) \
                GR_SET_LINE_STYLE,(style),(index)

This GString creation macro sets the style, or "dottedness," to use when drawing lines.

Include: gstring.h

GSSetLineWidth()

#define GSSetLineWidth(width_wwf) \
                GR_SET_LINE_WIDTH, GOC_WWF(width_wwf)

This GString creation macro sets the width to use when drawing lines. It takes a single argument, the width expressed as a WWFixed number.

Include: gstring.h

GSSetMiterLimit()

#define GSSetMiterLimit(limit_wwf) \
        GR_SET_MITER_LIMIT, GOC_WWF(limit_wwf)

This GString creation macro sets the miter limit to use when drawing mitered corners of rectangles, polylines, and polygons. This miter limit is expressed as a WWFixed value.

Include: gstring.h

GSSetMixMode()

#define GSSetMixMode(mode) GR_SET_MIX_MODE, (mode)

This GString creation macro sets the mix mode to use when drawing on top of existing drawings.

Include: gstring.h

GSSetNullPath()

#define GSSetNullPath() GR_SET_NULL_PATH

This GString creation macro clears the current path.

Include: gstring.h

GSSetNullTransform()

#define GSSetNullTransform() \
        GR_SET_NULL_TRANSFORM

This GString creation macro nullifies the coordinate transformation.

Include: gstring.h

GSSetPalette()

#define GSSetPalette(entry_count) GR_SET_PALETTE,(entry),(count)

This GString creation macro allows you to change several palette colors at once. It takes two arguments: the index of the first color entry to change, and the number of entries to change. Follow this macro with trios of bytes, each triplet specifying the red, green, and blue components of the colors.

GSSetPaletteEntry()

#define GSSetPaletteEntry(entry,r,g,b) \
        GR_SET_PALETTE_ENTRY GOC_WORD(entry),(r), (g),(b)

This GString creation macro changes a single entry in a custom palette. It takes four arguments: the index number of the entry and the red, green, and blue components of the new color for this entry.

Include: gstring.h

GSSetStrokePath()

#define GSSetStrokePath() GR_SET_STROKE_PATH

This GString creation macro replaces the current path with the path which results from stroking the current path with the current line attributes. This new path may be drawn, but may not be used for clipping.

Include: gstring.h
