jpg图片添加文字？？？

[jinzihan_005]

我的程序在image中已经加载了一幅jpg图片，现在我想在它的上面添加文字，并且保存下来，形成一张jpg图片（就是图片上必须有添加的文字），应该怎么做？？？

把JPG文件转成bmp格式的加载到image中，添加完文字后保存为jpg的文件，这样可以不？

转换到BMP,然后Canvas的TextOut输出,最后再保存为JPG的

bmp.Canvas.Font.Name:='宋体';
bmp.Canvas.Font.Size:=9;
bmp.Canvas.TextOut((bmp.Width div 2 - 30),(bmp.Height - 60),'测试写字');
image2.Picture.Bitmap.Assign(bmp);
jpg.Assign(bmp);
jpg.SaveToFile('e:\aa.jpg');
jpg.Free;
bmp.Free;
end;

end.
