shxpatch's Introduction

shxpatch

识别shx字体，返回路径，可以供二次开发代码使用，如：绘制路径，按shx字体显示文字等。

路径与数值定义

pendown

落笔

penup

起笔

moveto:12.0000,22.0000

移动到:x坐标,y坐标

lineto:42.0000,62.0000

直线画到:x坐标,y坐标

anglearc:12.0000,12.0000,25.0000,45.0000,45.0000

画圆弧:圆心x坐标,圆心y坐标,圆的半径,弧的起点角度,扇形的角度

返回路径字符串例子

pendown|penup|moveto:12.0000,22.0000|lineto:42.0000,62.0000|anglearc:12.0000,12.0000,25.0000,45.0000,45.0000

c++ 代码

int _tmain(int argc, _TCHAR* argv[])
{
	ShapeFont* m_font = new ShapeFont();
	if(m_font->Load("HT.SHX")){
		printf("已打开");
		printf("%i",m_font->Count());//字库包含多少字符
		//开始获得路径 例 '好' 字
		CString str("好");
		//获得 '好' 字编码
		char* kk=str.GetBuffer(0);
		wchar_t buf1[100];
		char key[8];
		MultiByteToWideChar(CP_OEMCP,0,str.GetBuffer(0),6,buf1,100);
		WideCharToMultiByte(932,0,buf1,3,key,6,NULL,NULL);
		unsigned short k1;
		memcpy(&k1,&kk[0],2);
		//获得shx字体路径
		string patch = m_font->Patch(k1,20,20,1,1);
		printf("%s",patch.c_str());
	}
	else{
		printf("字库打开错误");
	}

	return 0;
}

代码打包后制作了一个dll

c# 调用 dll 代码

//引用
[DllImport("ShxPatch.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)]
static extern IntPtr GetPatch(String file, UInt16 code, Single orgX, Single orgY, Single scX, Single scY);

//获得 '好' 字编码
byte[] big5 = System.Text.Encoding.GetEncoding("GBK").GetBytes("好");
ushort code = big5[0];
if (big5.Length > 1)
{
	code = (ushort)System.BitConverter.ToInt32(new byte[] { big5[0], big5[1], 0x00, 0x00 }, 0);
}
//获得shx字体路径
IntPtr ipt = GetPatch("HT.SHX", code, 0, 0, 1, 1);
