DrawStippleLineInt

Draws a stippled, single pixel wide line with integer coordinates.

Declaration

void NAPI GA_2DRenderFuncs::DrawStippleLineInt(
    N_int32 x1,
    N_int32 y1,
    N_int32 x2,
    N_int32 y2,
    N_int32 drawLast,
    N_int32 transparent)

Prototype In

snap/graphics.h

Parameters

x1

X1 coordinate

y1

Y1 coordinate

x2

X2 coordinate

y2

Y2 coordinate

drawLast

1 to draw last pixel, 0 to skip it

transparent

1 if the line is transparent, 0 if opaque

 

Description

This function renders a stippled line at the specified location and the currently active colors, mix and stipple pattern. This routine will render a line from (x1,y1) to (x2,y2) inclusive. If the drawLast parameter is set, the last pixel in the line (x2,y2) will be drawn, otherwise it will be skipped. This feature allows multiple lines to be linked together as a polyline for CAD style operations while drawing in XOR mode (and is also required for compatibility with Microsoft Windows).

If the transparent parameter is set to 1, where a bit is 0 in the stipple pattern the destination pixel remains untouched. If the transparent parameter is set to 0, where a bit is 0 in the stipple pattern the destination pixel is drawn in the background color. In all cases where a bit in the stipple pattern is 1, the pixel is drawn in the foreground color.
