最好有API，通过对API编程来控制数据保存到数据库中

用Stream对象;保存到Blob型字段里就行了

对！就是将图象文件以流的方式进行读写

谢谢各位的答复．我要问的主要目的是怎样抓到扫描的图片，打个比方．点击扫描并保存按扭．然后开始扫描．完了直接把扫描的图片放到库里．最好给段代码．只要中间怎样得到扫描图片到保存开始那个过度段．至于控制扫描仪和转化成流不用劳驾各位大侠了．在线等待．完了给分

呵呵，楼主可真够懒的阿。都没看我给你的地址

procedure Tscanf.N1Click(Sender: TObject);
begin
ImgScan1.ShowSelectScanner;
//选择系统中已安装的扫描仪
end;

procedure Tscanf.N2Click(Sender: TObject);
begin
imgedit1.zoom:=100; //设置图象的放缩因子
if not imgscan1.ScannerAvailable then
//如果选择的扫描仪不可用
imgscan1.OpenScanner;//打开扫描仪
imgscan1.StartScan; //开始扫描图象
imgscan1.CloseScanner; //关闭扫描仪
end;


procedure Tscanf.N8Click(Sender: TObject);
begin
if (imgedit1.IsClipboardDataAvailable
and imgedit1.ImageDisplayed ) then
imgedit1.ClipboardPaste(selleft,seltop);
//从剪贴板粘贴图象，其参数为Imgedit的显示区域的起始坐标
end;

procedure Tscanf.N1801Click(Sender: TObject);
begin
if imgedit1.ImageDisplayed then
imgedit1.Flip; //镜象图象
end;

procedure Tscanf.N901Click(Sender: TObject);
begin
if imgedit1.ImageDisplayed then
imgedit1.RotateRight //向右旋转图象
end;
procedure Tscanf.N6Click(Sender: TObject);
begin
imgedit1.DrawSelectionRect(selleft,
seltop,selwidth,selheight);//进行图象局部选择
imgedit1.ClipboardCut(selleft,seltop,
selwidth,selheight);//剪切所选区域
end;

接受答案了.
