[Gdal-dev] gdal_translate image grow

[Norman Barker]

Hi,

 

I am using gdal_translate as the 'engine' behind mod_python as a very
simple WMS (so that I can prototype a few ideas before putting them into
MapServer), everything works fine until I specify a BBOX such that the
extents are outside that of the requested image.  This corresponds to
the -projwin option of gdal_translate, executing this I then get an
error "-srcwin falls outside of raster size".

 

Is there a way to grow the output image and fill in the missing data?

 

So for example

 

gdal_translate -not_strict -OF PNG -a_nodata 0 -projwin -180 90 180 -90
-outsize 836 654 inputimage outputimage

 

would give an output image with world extents, and somewhere in this
image would be the inputimage

 

Alternatively is there a way to do this with the python bindings or any
other utility.  I like gdal_translate since it does the conversion and
sampling in one go!

 

thanks 

 

Norman

Subject: [Gdal-dev] GDAL and Intergraph .cmp files

 

Dear List,

 

We are using Integraph software (Geomedia, Orthopro...) in our
organization.

Intergraph uses by default a compressed raster file format for it's
raster data (extension .cmp).

 

Does anyone knows if there's have been done some work to support this
format in de GDAL 

environment?

 

Thank you all in advance for any tips or help,

 

Luc
