前言

本文簡單實現java呼叫GDAL實現影像格式轉換。

        gdal.AllRegister();

        //設定中文
        gdal.SetConfigOption("gdal_FILENAME_IS_UTF8", "YES");

        //只讀方式讀取資料
        Dataset ds=gdal.Open(INPUT_PATH,gdalconstConstants.GA_ReadOnly);

        //判斷資料來源是否非空
        if (ds==null)
        {
            System.err

        Driver hDriver=ds.GetDriver();
        System.out.println("Driver: "+hDriver.getShortName()+"/"+hDriver.getLongName());

        hDriver.CreateCopy

        ds.delete();
        hDriver.delete();
        System.out.println("Suscess!");
    }
