Answer 1

private void jpgToolStripMenuItem_Click(object sender, EventArgs e)
{
Gdal.AllRegister();
Gdal.SetConfigOption("GDAL_FILENAME_IS_UTF8", "YES");

string filePathName = "";

OpenFileDialog dlg = new OpenFileDialog();

if (dlg.ShowDialog() == DialogResult.OK)
{
\\filename保存了路径加文件名
filePathName = dlg.FileName;
}

if (filePathName == "")
{
MessageBox.Show("影像路径不能为空");
return;
}

Dataset ds = Gdal.Open(filePathName, Access.GA_ReadOnly);

Driver drv = ds.GetDriver();
if (drv == null)
{
MessageBox.Show("Can't get driver!");
System.Environment.Exit(-1);
}
string strSavePathName = @"E:\TEMP\TifToJpg\myJpg1.jpg";
drv.CreateCopy(strSavePathName,ds,0,null,null,null); \\tif转换成jpg
drv.CreateCopy(@"E:\TEMP\TifToJpg\myBmp1.bmp", ds, 0, null, null, null);\\tif转换成bmp
drv.CreateCopy(@"E:\TEMP\TifToJpg\myPng1.png", ds, 0, null, null, null);\\tif转换成png
drv.CreateCopy(@"E:\TEMP\TifToJpg\myGif1.gif", ds, 0, null, null, null);\\tif转换成gif
MessageBox.Show("另存成功！");
}
