[gdal-dev] gdalwarper --formats inconsistent with -of flag?

[Chaitanya kumar CH]

Sam,

I too noticed this problem. I'm not sure of the reason other than the error
message.
You can get this done in two steps.
First use gdalwarp to change the image size to 256x256 using bilinear
resampling into a GTiff format image.
Then use gdal_translate it from GTiff to PNG.
