Question

我需要在C＃中使用Visual Studio制作图形，但是当我设置这样的点时：

module DSD_Project(flag0, flag1, hit0, hit1,room_counter,someone_inRoom,someone_Spying,hit0_LED, hit1_LED,echo0_LED, echo1_LED, anti_theft_output,reset_Antitheft_output,echo0, echo1, CLOCK_50,anti_theft, reset_Antitheft);

    output reg hit0_LED = 1'b0;
    output reg hit1_LED = 1'b0;
    output reg echo0_LED = 1'b0;
    output reg echo1_LED = 1'b0;
    output reg flag0 = 1'b0;
    output reg flag1 = 1'b0;
    output reg hit0 = 1'b0;
    output reg hit1 = 1'b0;
    output reg room_counter = 1'b0;
    output reg someone_inRoom = 1'b0;
    output reg someone_Spying = 1'b0;
    output reg anti_theft_output = 1'b0;
    output reg reset_Antitheft_output = 1'b0;
    input echo0; // input_signal from the sensor 1
    input echo1;// input_signal from the sensor 2
    input CLOCK_50;
    input anti_theft ;   //= 1'b0; // switch button
    input reset_Antitheft; // = 1'b0; // push button

    sensor s1(hit0, echo0) ; // , CLOCK_50);
    sensor s2(hit1, echo1) ; // , CLOCK_50);

    always@(posedge CLOCK_50)
        begin           
            hit0_LED <= hit0;
            hit1_LED <= hit1;
             echo0_LED <= echo0;
             echo1_LED <= echo1;     
        end

    //anti_theft: seting and reseting the output 
    //always@(anti_theft)  //or reset_Antitheft)
        //begin
            //anti_theft_output <= anti_theft ;
            //reset_Antitheft_output <= reset_Antitheft ;
        //end

    always@(posedge hit0 or posedge hit1)
        begin     
            if (hit0 == 1 && hit1== 0)
                begin
                    flag0<= 1;
                    //flag1<= 0;
                    if(flag1==0)
                        begin
                            hit0=0;
                            room_counter <= room_counter +1 ;
                            someone_inRoom <=1 ;
                            if(anti_theft == 1)
                                someone_Spying <= 1;
                        end
                    else
                    flag1<=0;               
                end
         else
            begin
                if ((hit0 == 0) && (hit1 == 1))
            begin
                    //flag0<=0;
                    flag1<=1;
                    if(flag0 == 0)
                        begin
                            hit1=0;
                            room_counter <= room_counter -1 ;

                            if(room_counter==0)
                                begin

                                end

            end
     end 
     always@(reset_Antitheft)
     begin
     if( (anti_theft==1) && (someone_Spying == 1) )
        begin
            anti_theft_output <= 0 ;
            someone_Spying <= 0 ;
        end
     end 
endmodule


module sensor(hit, input_signal); //, CLOCK_50);

    input input_signal;   
    output reg hit = 1'b0; 
    //reg [25:0] clock_counter;

    always@(input_signal) // posedge CLOCK_50 ||
      begin
            //if (clock_counter == 8_000_000)   
                begin               
                    if (input_signal==1)
                        begin 
                            hit <= 1;                  
                        end
                    else
                        begin
                            hit <= 0;      
                        end

我的矩形显然从面板上飞过，因为在C＃中高度向下增加，有没有办法解决这个问题？我不能将起点设置得更高并让它向下移动，因为我写的程序需要接收数据。

P.S。我知道有一种更简单的方法可以在C＃中绘制图形，但这适用于学校作业，我只允许使用DrawRectangle或FillRectangle功能。

Answer 1

您可以移动Graphics对象并像这样镜像：

 g.TranslateTransform(0, Height);
 g.ScaleTransform(1, -1);

现在你可以向上画了：

 e.Graphics.DrawRectangle(pen, 10, 300, 30, 400);

请注意，此处Height是Form.Height。如果您绘制其他任何内容（包括Bitmap），则需要使用其高度！

如果你不想从最底层开始，只需使用较小的数字......！

我可以在C＃中反转DrawRectangle / FillRectangle的方向吗？
