Question

我试图通过将ENVI图像转换为PNG图像（即RGB文件）来显示4GB的ENVI图像。根据.hdr头文件，执行此操作的默认波段为：{55,41,12}

我正在使用gdal_translate;我得到了一个黑色图像，但有一些空白的风险。

我使用以下命令行：

gdal_translate -of PNG D:\files\hdr\image D:\file\hdr\test.png -b 55 -b 41 -b 12

我做错了什么？我试图改变乐队的顺序，把选项-ot Byte，-ot Uint16，但没有成功......

我还尝试使用java语言转换此图像，但是也没有成功。如有必要，我也可以在这里提供源代码。
