[Gdal-dev] read RLE BIL with GDAL?

[Thom DeCarlo]

Yep, I knew that. I should have said RLE compression and not RLE format.
Sorry for the confusion. I didn't realize that Brent was asking about
something specific to ArcGIS, so I can't answer whether or not the schemes
are the same.

Sorry again,
Thom

Thom,

RLE stands for "Run length encoded".  There are a variety of approches to
run length encoding including stuff like the packbits compression in
TIFF.  Do you know if the SGI RLE format used the same exact format as
the RLE supported by ArcGIS?  If so, I might be able to dig up info on it.
Although, it still wouldn't be too high on my priority list.

Best regards,
