不知道明白没有?下面给你一个‘相片.为jpg格式’的TAB文件的例子:
!table
!version 300
!charset WindowsSimpChinese
Definition Table
File "AA.jpg"
Type "RASTER"
(104.019585,30.372237) (1405,3196) Label "Pt 1",
(104.018017,30.427076) (1356,529) Label "Pt 2",
(104.067306,30.407744) (3495,1458) Label "Pt 3"
CoordSys Earth Projection 1, 0
Units "degree"
其中AA.jpg是你的文件名,上面的内容在AA.TAB文件中。
(104.019585,30.372237)是经纬度 (1405,3196) 是对应的像素值
明白了吗?
