Question

net生成缩略图代码，是整张图片缩小，不是裁剪多大多大的图片

Answer 1

见代码strOldPic是旧图片路径，strNewPic是输出小图路径，后面俩参数应该不用解释了。。

private void SmallPic(string strOldPic, string strNewPic, int intWidth, int intHeight)
{
System.Drawing.Bitmap objPic, objNewPic;
try
{
objPic = new System.Drawing.Bitmap(strOldPic);
objNewPic = new System.Drawing.Bitmap(objPic, intWidth, intHeight);
objNewPic.Save(strNewPic);
}
catch (Exception exp)
{ throw exp; }
finally
{
objPic = null;
objNewPic = null;
}
}
