[Gdal-dev] Computing histograms for output files

[Michael Lefsky]

I have been using GDAL to create erdas Imagine .img files (i.e. HFA 
format). The HFA format includes a histogram of each band as part of its 
data structure. When I open these files in Imagine, I can compute a 
histogram, and work with the files that way. However, I would like to open 
these files directly in ArcGis, and when I open these files in Arcgis 
(without previously calculating the histograms in Imagine) ArcGis crashes.

Is there a way of adding these histograms within GDAL? As an added 
complication, I am creating Float32 files (from python), not standard Int8 
files.
