我是一个刚入行的程序员,老板给的活让我十分苦恼.我不知该如何做这个程序,问题是这样的:公司是一个做手机的公司,而我是公司IT部的程序员,做一些小程序在公司内部使用.现在老板要在仓库里贴物料条形码,这个条形码由条形码打印机打出来,这个条形码打印程序由我来做,我要发疯了,我从来就没做过这样的程序.下面是我没来公司前一个跳槽走了的程序员用DELPHI写的代码:
function GetGraphyData(Img : TImage; var Data : String;var r_width_byte, r_total_byte : Integer) : Integer;
var
l_i0, l_i1, l_j1, l_i, l_j, l_x, l_y, l_width, l_height, l_count : Integer;
l_string0, l_string : String;
begin
l_x := 0;
l_y := 0; with Img.Canvas do
begin l_width := img.Width;
l_height := img.Height; l_i0 := l_width div 4 + 1;
if l_width mod 4 = 0 then
begin
l_i0 := l_width div 4;
end;
if l_i0 mod 2 = 1 then
begin
l_i0 := l_i0 + 1;
end; l_string := '';
for l_j := 1 to l_height do
begin
for l_i := 1 to l_i0 do
begin
l_i1 := l_x + (l_i - 1) * 4;
l_j1 := l_y + l_j;
l_count := 0;
if Pixels[l_i1, l_j1] = clBlack then
begin
l_count := l_count + 8;
end;
if Pixels[l_i1+1, l_j1] = clBlack then
begin
l_count := l_count + 4;
end;
if Pixels[l_i1+2, l_j1] = clBlack then
begin
l_count := l_count + 2;
end;
if Pixels[l_i1+3, l_j1] = clBlack then
begin
l_count := l_count + 1;
end;
case l_count of
15 : l_string0 := 'F';
14 : l_string0 := 'E';
13 : l_string0 := 'D';
12 : l_string0 := 'C';
11 : l_string0 := 'B';
10 : l_string0 := 'A';
9,8,7,6,5,4,3,2,1,0 : l_string0 := IntToStr(l_count);
else l_string0 := '0';
end;
l_string := l_string + l_string0;
end;
end;
end; r_width_byte := l_i0 div 2;
r_total_byte := r_width_byte * l_height;
Data := l_string;
Result := r_total_byte;
