示例1: drawPolygon

void Design::drawPolygon(Graphics::ManagedSurface *surface, Common::ReadStream &in,
	Patterns &patterns, byte fillType, byte borderThickness, byte borderFillType) {

	byte ignored = in.readSint16BE(); // ignored

	if (ignored)
		warning("Ignored: %d", ignored);

	int numBytes = in.readSint16BE(); // #bytes used by polygon data, including the numBytes
	int16 by1 = in.readSint16BE();
	int16 bx1 = in.readSint16BE();
	int16 by2 = in.readSint16BE();
	int16 bx2 = in.readSint16BE();
	Common::Rect bbox(bx1, by1, bx2, by2);

	numBytes -= 8;

	int y1 = in.readSint16BE();
	int x1 = in.readSint16BE();

	Common::Array<int> xcoords;
	Common::Array<int> ycoords;

	numBytes -= 6;

	while (numBytes > 0) {
		int y2 = y1;
		int x2 = x1;
		int b = in.readSByte();
		if (b == -128) {
			y2 = in.readSint16BE();
			numBytes -= 3;
		} else {
			y2 += b;
			numBytes -= 1;
		}
		b = in.readSByte();

			x2 = in.readSint16BE();
			numBytes -= 3;
		} else {
			x2 += b;
			numBytes -= 1;
		}
		xcoords.push_back(x1);
		ycoords.push_back(y1);
		x1 = x2;
		y1 = y2;
	}
	xcoords.push_back(x1);
	ycoords.push_back(y1);

	int npoints = xcoords.size();
	int *xpoints = (int *)calloc(npoints, sizeof(int));
	int *ypoints = (int *)calloc(npoints, sizeof(int));
	for (int i = 0; i < npoints; i++) {
		xpoints[i] = xcoords[i];
		ypoints[i] = ycoords[i];
	}

	PlotData pd(surface, &patterns, fillType, 1, this);

	if (fillType <= patterns.size()) {
		Graphics::drawPolygonScan(xpoints, ypoints, npoints, bbox, kColorBlack, drawPixel, &pd);
	}

	pd.fillType = borderFillType;
	pd.thickness = borderThickness;
	if (borderThickness > 0 && borderFillType <= patterns.size()) {
		for (int i = 1; i < npoints; i++)
			Graphics::drawLine(xpoints[i-1], ypoints[i-1], xpoints[i], ypoints[i], kColorBlack, drawPixel, &pd);
	}

	free(xpoints);
	free(ypoints);
