[gdal-dev] Error writing/reading simple ENVI file

[Calogero Mauceri]

Hi all,

I am having some problems converting a very simple TIFF file to an ENVI
format one.
The file is one band file with just two values (longitudes around 145 deg).

>gdalinfo test.tiff -mm
Driver: GTiff/GeoTIFF
Files: test.tiff
Size is 2, 1
Coordinate System is `'
Image Structure Metadata:
  INTERLEAVE=BAND
Corner Coordinates:
Upper Left  (    0.0,    0.0)
Lower Left  (    0.0,    1.0)
Upper Right (    2.0,    0.0)
Lower Right (    2.0,    1.0)
Center      (    1.0,    0.5)
Band 1 Block=2x1 Type=Float64, ColorInterp=Gray
    Computed Min/Max=145.333,145.351


I convert the file to ENVI format using gdal_translate command:
>gdal_translate -of ENVI test.tiff test.IMG


The command does not give any errors. When I read back the ENVI file I get
the following error:

>gdalinfo test.IMG -mm
ERROR 1: A marker ID was expected (0xff--) instead of 000028fc

ERROR 1: opj_read_header() failed
gdalinfo failed - unable to open 'my_path\test.IMG'.

I'm not sure why it tries to open the ENVI file using the OpenJPEG reader.
Anyway I'm using GDAL 2.4.4 and OpenJPEG 2.3.0. I tried GDAL 3.1.2, but I
get the same error.
I also tried to gdalinfo the ENVI file with an older version of GDAL
(2.1.1) and it can properly read it. Here is the output

>gdalinfo test.IMG -mm
Driver: ENVI/ENVI .hdr Labelled
Files: test.IMG
      test.hdr
Size is 2, 1
Coordinate System is `'
Image Structure Metadata:
  INTERLEAVE=BAND
Corner Coordinates:
Upper Left  (    0.0,    0.0)
Lower Left  (    0.0,    1.0)
Upper Right (    2.0,    0.0)
Lower Right (    2.0,    1.0)
Center      (    1.0,    0.5)
Band 1 Block=2x1 Type=Float64, ColorInterp=Undefined
    Computed Min/Max=145.333,145.351

I wonder whether I'm doing something wrong in creating the file or whether
this is a problem in the ENVI driver.
Attached are both input TIFF and output ENVI file generated by
gdal_translate.

Thanks in advance for your help,
Calogero
