DrawPattScanList

Draws a list of monochrome patterned scanlines.

Declaration

void NAPI GA_2DRenderFuncs::DrawPattScanList(
N_int32 y,
N_int32 length,
N_int16 *scans)

Prototype In

snap/graphics.h

Parameters

y | Y coordinate for scanline
length | Number of scanlines in the list
scans | Pointer to an array of scanline data

Description

This function renders a list of monochrome patterned scanlines starting at the specified location in the currently active colors, mix and monochrome pattern. The scanline coordinates are passed as an array of 16-bit integer coordinates, packed with the X1 coordinate followed by the X2 coordinate and so on. For each scanline in the list, this routine will render a scanline from X1 to X2 (exclusive) at increasing Y coordinates. For scanlines where X2 < X1, the X1 and X2 coordinates will be swapped, and for scanlines where X1 = X2, the scanline will be skipped and nothing will be drawn.
