本例效果图:
;
Page_edge := StrToIntDef(LabeledEdit2.Text, 0);
Word_h := bit.Canvas.TextHeight('a');
Line_h := StrToIntDef(LabeledEdit3.Text, 0);
{设置页面高度}
bit.Height := (Word_h + Line_h) * Memo1.Lines.Count - Line_h + Page_edge * 2;
w := 0;
x := Page_edge;
y := Page_edge;
for i := 0 to Memo1.Lines.Count - 1 do
begin
{设置页面宽度}
if bit.Canvas.TextWidth(Memo1.Lines[i]) > w then
begin
w := bit.Canvas.TextWidth(Memo1.Lines[i]);
bit.Width := w + Page_edge * 2;
end;
{画文本}
bit.Canvas.TextOut(x, y, Memo1.Lines[i]);
{下一行}
Inc(y, Word_h + Line_h);
end;
{保存为图片}
bit.SaveToFile(FilePath);
bit.Free;
end;
end.
