[gdal-dev] help:About Getting StyleString

[Randyqiu]

Hi,

  I have been in trouble with getting S_57 format(.000) files¡¯
¡°styleString¡±. 

 According to the article named ¡°OGR - Feature Style
<http://www.gdal.org/ogr/ogr_feature_style.html>  Specification¡±, I wanted
to get some information about ¡°drawing tools¡± such as color¡¢pen width by
using some functions as follows:

 OGRLayer::GetStyleTable ()¡¢OGRFeature::GetStyleString()¡¢OGRDataSource::
GetStyleTable()

But they all returned nothing(0x000000) which means these functions were
useless and didn¡¯t get what I want .

Now, can you tell me the reason? Is it because I used the wrong function or
anything else? Can you give me an instance about getting the ¡°StyleString¡±
or ¡°drawing tools¡± information?

 Thanks, any suggestion or help will be appreciated!!!
