[gdal-dev] Dxf output wrong in gdal 1.9 and correct in gdal 1.8

[Lorenzo Moretti]

Hi

There are some problems in gdal 1.9.1. There are errors in dxf output when I use ogr2ogr.

I have  a simple shape file with some polylines. I want to convert it in dxf file.

The same command
GDAL 1.8
ogr2ogr -f "DXF" -t_srs EPSG:3004 "/Volumes/myhd/ustgdal18.dxf" -s_srs EPSG:32633 "/Volumes/myhd/ust.shp"

GDAL 1.9.1
ogr2ogr -f "DXF" -t_srs EPSG:3004 "/Volumes/myhd/ustgdal19.dxf" -s_srs EPSG:32633 "/Volumes/myhd/ust.shp"


creates two different DXF files

The first one, in gdal 1.8, is correct. It create a perfect DXF file. The size is 59kB.
The second one, in gdal 1.9, is wrong: it lost many polylines and the size is 62kB.

I have analyzed the two dxf file.

The correct file in gdal 1.8 has the perfect attribute for polylines:

100
AcDbEntity
100
AcDbPolyline
 70
1
 90
5
 10
2420094.24101526

.............


The wrong DXF file in gdal 1.9 changes the attribute for polyline with hatch attribute:

100
AcDbEntity
100
AcDbHatch
  2
SOLID
 70
1
 71
0
 91
1
 92
2
 72
0
 73
1
 93
7
 10
2420032.16360568

.............


This is an error.


Is this a bug in gdal 1.9.1 ?
