shape.c

Nxlib,一个模拟xlib的程序。使用microwindows的库来运行需要xlib支持的程序。

#include "nxlib.h"

	Pixmap src, int op)

	if (destKind != ShapeBounding || op != ShapeSet)
	//if (destKind != ShapeClip || op != ShapeSet)

	if (src == None) {
		GrSetWindowRegion(dest, 0, 0);
		return;
	}

	GrGetWindowInfo(src, &info);
	mask = GrNewRegionFromPixmap(src, 0, 0, info.width, info.height);
	GrSetWindowRegion(dest, mask, mask);
	GrDestroyRegion(mask);
