JAVA调用GDAL实现影像格式转换,以tif to jpg为例




前言

本文简单实现java调用GDAL实现影像格式转换。

package Marcus.com;

import org.gdal.gdal.Dataset;
import org.gdal.gdal.Driver;
import org.gdal.gdal.gdal;
import org.gdal.gdalconst.gdalconstConstants;

public class tif2jpg {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        String INPUT_PATH="D:/airplane20.tif";
        String OUTPUT_PATH="D:/airplane20.jpg";

        //注册GDAL
        gdal.AllRegister();

        //设置中文
        gdal.SetConfigOption("gdal_FILENAME_IS_UTF8", "YES");

        //只读方式读取数据
        Dataset ds=gdal.Open(INPUT_PATH,gdalconstConstants.GA_ReadOnly);

        //判断数据源是否非空
        if (ds==null)
        {
            System.err.println("GDALOpen failed-"+gdal.GetLastErrorNo());
            System.err.println(gdal.GetLastErrorMsg());         
            System.exit(1);
        }

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

        hDriver.CreateCopy(OUTPUT_PATH, ds);


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

}
